These social and emotional skills are just as important for school success, she says. But experts say that preschoolers (ages 3-5) also benefit a great deal from the informal learning experiences that parents can build into everyday interactions and routines. Heres how you can foster your childs interest in reading, writing, counting, and more. Building reading and Writing skills, you can prepare your child for reading and writing when you: read aloud to your child and discuss the characters, pictures, and events in the book. Ask your child questions, such as: What do you see in this picture? Or What do you think the bears will do next?

) to create a file with pre-set permissions. You can also create a new file by using the newOutputStream methods, as described in Creating and Writing a file using Stream I/O. If you open a new output stream and close it immediately, an empty file is created. Creating Temporary files you can create a temporary file using one of the following createTempFile methods: The first method allows the code to specify a directory for the temporary file and the second method creates a new file in the default temporary-file directory. Both methods allow you to specify a suffix for the filename and the first method allows you to also specify a prefix. The following code snippet gives an example of the second method: try path tempFile eateTempFile(null, ".myapp rmat The temporary file" " has been created: sn tempFile) ; catch (IOException x) rmat ioexception: sn x the result of running this file would be something like the. When it comes to helping your preschool-aged child work on language and math skills, its best to find games and activities you both enjoy. This can lay the foundation for a positive attitude toward learning. My perspective is that whatever parents summary do to teach children this age, they need to make it playful and fun, says Pamela high, md, professor of pediatrics at The warren Alpert Medical School of Brown University and director of the division of developmental-behavioral pediatrics. You dont want children to turn off to it because its too difficult for them. High tells WebMD that a good preschool or other early education program can help your child learn basic language and math concepts, as well as skills like being able to share and get along with other children.

Write(bb catch (IOException x) intln Exception thrown: " x creating Files you can create an empty file with an initial set of attributes by using the resume createFile(Path, fileAttribute? For example, if, at the time of creation, you want a file to have a particular set of file permissions, use the createFile method to. If you do not specify any attributes, the file is created with default attributes. If the file already exists, createFile throws an exception. In a single atomic operation, the createFile method checks for the existence of the file and creates that file with the specified attributes, which makes the process more secure against malicious code. The following code snippet creates a file with default attributes: Path file.; try / Create the empty file with default permissions, etc. EateFile(file catch (FileAlreadyExistsException x) rmat file named s" " already existsn file catch (IOException x) / Some other sort of failure, such as permissions.

Length catch (IOException x) intln(x reading and Writing Files by Using Channel I/O While stream I/O reads a character at a time, channel I/O reads a buffer at a time. The byteChannel interface provides basic read and write functionality. A seekableByteChannel is a byteChannel that has the capability to maintain a position in the channel and to change that position. A seekableByteChannel also supports truncating the file associated with the channel and querying the file for its size. The capability to move to different points in the file and then read from or write to that location makes random access of a file possible.

See random Access Files for more paper information. There are two methods for reading and writing channel I/O. Note: The newByteChannel methods return an instance of a seekableByteChannel. With a default file system, you can cast this seekable byte channel to a fileChannel providing access to more advanced features such mapping a region of the file directly into memory for faster access, locking a region of the file so other processes cannot access. Both newByteChannel methods enable you to specify a list of OpenOption options. The same open options used by the newOutputStream methods are supported, in addition to one more option: read is required because the seekableByteChannel supports both reading and writing. Specifying read opens the channel for reading.

The following code snippet shows how to create a file encoded in "us-ascii" using this method: Charset charset rName us-ascii string.; try (BufferedWriter writer wBufferedWriter(file, charset) writer. Length catch (IOException x) rmat ioexception: sn x reading a file by Using Stream I/o to open a file for reading, you can use the newInputStream(Path, OpenOption.) method. This method returns an unbuffered input stream for reading bytes from the file. Path file.; try (InputStream in wInputStream(file bufferedReader reader new BufferedReader(new InputStreamReader(in) String line null; while (line adLine! Null) intln(line catch (IOException x) intln(x creating and Writing a file by Using Stream I/o you can create a file, append to a file, or write to a file by using the newOutputStream(Path, OpenOption.) method. This method opens or creates a file for writing bytes and returns an unbuffered output stream.


The method takes an optional OpenOption parameter. If no open options are specified, and the file does not exist, a new file is created. If the file exists, it is truncated. This option is equivalent to invoking the method with the create and truncate_existing options. The following example opens a log file. If the file does not exist, it is created. If the file exists, it is opened for appending. public class LogFileTest public static void main(String args) / Convert the string to a / byte array. String s "Hello world!

Write(file, buf The le package supports channel I/O, which moves data in reviews buffers, bypassing some of the layers that can bottleneck stream I/O. Reading a file by Using Buffered Stream I/O. The newBufferedReader(Path, Charset) method opens a file for reading, returning a bufferedReader that can be used to read text from a file in an efficient manner. The following code snippet shows how to use the newBufferedReader method to read from a file. The file is encoded in "us-ascii.".

Dsync keeps the file content synchronized with the underlying storage device. Reading All Bytes or Lines from a file. If you have a small-ish file and you would like to read its entire contents in one pass, you can use the readAllBytes(Path) or readAllLines(Path, Charset) method. These methods take care of most of the work for you, warming such as opening and closing the stream, but are not intended for handling large files. The following code shows how to use the readAllBytes method: Path file.; byte fileArray; fileArray adAllBytes(file writing All Bytes or Lines to a file. You can use one of the write methods to write bytes, or lines, to a file. The following code snippet shows how to use a write method. Path file.; byte buf.; Files.

opens the file if it exists or creates a new file if it does not. Delete_ON_close deletes the file when the stream is closed. This option is useful for temporary files. Sparse hints that a newly created file will be sparse. This advanced option is honored on some file systems, such as ntfs, where large files with data "gaps" can be stored in a more efficient manner where those empty gaps do not consume disk space. Sync keeps the file (both content and metadata) synchronized with the underlying storage device.

To the right of those are the methods for dealing with ByteChannels, seekableByteChannels, and ByteBuffers, such as the newByteChannel method. Finally, on the far right are the methods that use fileChannel for advanced applications needing file locking or memory-mapped I/O. Note: The methods for creating a new file enable you to specify an optional set of initial attributes for the file. For example, on a file system that supports the posix set of standards (such as unix you can specify a file owner, group owner, or file permissions at pelleas the time the file is created. Managing Metadata page explains file attributes, and how to access and set them. This page has the following topics: several of the methods in this section take an optional OpenOptions parameter. This parameter is optional and the api tells you what the default behavior is for the method when none is specified. The following StandardOpenOptions enums are supported: write opens the file for write access. Append appends the new data to the end of the file.

This page discusses the details of reading, writing, creating, and opening files. There are a wide array of file I/O methods to choose from. To help make sense of the api, the following diagram arranges the file I/O methods by complexity. File I/o methods Arranged from Less Complex to more complex. On the far left of the diagram are the utility methods readAllBytes, readAllLines, and the write methods, designed for simple, common cases. To the right of those are the methods used to iterate over a stream or lines of text, such as newBufferedReader, restaurant newBufferedWriter, then newInputStream and newOutputStream. These methods are interoperable with the package.
