Document

Reads ints from the current position into the specified int array, starting from the specified offset, and increases the position by the number of ints read.

Usage

From source file:Main.java

public static void main(String[] args) {
    IntBuffer bb = IntBuffer.allocate(10);
    bb.put(100);//  w  w  w  .ja v a 2s .co m

    bb.rewind();

    int[] intArray = new int[10];
    bb.get(intArray, 0, 2);

    System.out.println(Arrays.toString(intArray));

}
