Prototype

public IntBuffer put(IntBuffer src)

Source Link

Document

Writes all the remaining ints of the src int buffer to this buffer's current position, and increases both buffers' position by the number of ints copied.

Usage

From source file:MainClass.java

public static void main(String[] args) throws IOException {
    FileChannel fc = new RandomAccessFile(new File("temp.tmp"), "rw").getChannel();
    IntBuffer ib = fc.map(FileChannel.MapMode.READ_WRITE, 0, fc.size()).asIntBuffer();
    ib.put(0);
    for (int i = 1; i < 10; i++)
        ib.put(ib.get(i - 1));//from w  ww.  j  ava2  s  . c  o m
    fc.close();

}

From source file:IntBufferDemo.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.allocate(BSIZE);
    IntBuffer ib = bb.asIntBuffer();
    // Store an array of int:
    ib.put(new int[] { 11, 42, 47, 99, 143, 811, 1016 });
    // Absolute location read and write:
    System.out.println(ib.get(3));
    ib.put(3, 1811);/*w ww . ja  v  a 2s  .c  o  m*/
    ib.rewind();
    while (ib.hasRemaining()) {
        int i = ib.get();
        if (i == 0)
            break; // Else we'll get the entire buffer
        System.out.println(i);
    }
