CharArrayReader Class in Java

CharArrayReader Class in Java

CharArrayReader class is a character input stream that uses a character array as the source of the characters it returns. we create a CharArrayReader by specifying the character array, or portion of an array, that it is to read from.

The character array we pass to the CharArrayReader is not copied by this class. This means that changes we make to the elements of the array after we create the input stream do affect the values read from the array.

CharArrayReader defines the normal Reader methods, and supports the mark () and reset () methods.

The class CharArrayReader is defined as

public class java.io.CharArrayReader extends java.io.Reader{
// Public Constructors
public CharArrayReader (char [ ] buf);
public CharArrayReader (char [ ] buf, int offset, int length);
// Protected Instance Variables

// Public Instance Methods
