Examples of java.nio.CharBuffer

java.nio.CharBuffer
A buffer of chars.
A char buffer can be created in either of the following ways:
- {@link #allocate(int) Allocate} a new char array and create a bufferbased on it;
- {@link #wrap(char[]) Wrap} an existing char array to create a newbuffer;
- {@link #wrap(CharSequence) Wrap} an existing char sequence to create anew buffer;
- Use {@link java.nio.ByteBuffer#asCharBuffer() ByteBuffer.asCharBuffer}to create a char buffer based on a byte buffer.
