Returns the short at the current position and increases the position by 2.

Usage

From source file:Main.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.allocate(BSIZE);

    bb.asShortBuffer().put((short) 471142);
    bb.rewind();//from   w w  w .ja va 2s .c  o m
    System.out.println(bb.getShort());

}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer buf = ByteBuffer.allocate(100);

    buf.putShort((short) 123);

    // Reset position for reading
    buf.flip();/*from  w  w w.j  a  v  a 2s.  c o m*/

    // Retrieve the values
    short s = buf.getShort();

}

From source file:Main.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.allocate(BSIZE);
    bb.asCharBuffer().put("Howdy!");
    char c;/*ww w .  ja  va2  s.  c o m*/
    while ((c = bb.getChar()) != 0)
        System.out.print(c + " ");
    System.out.println();

    bb.rewind();
    // Store and read a short:
    bb.asShortBuffer().put((short) 471142);
    System.out.println(bb.getShort());

}

From source file:GetData.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.allocate(BSIZE);
    // Allocation automatically zeroes the ByteBuffer:
    int i = 0;//from w  w  w .  ja  v a2  s  .  c o  m
    while (i++ < bb.limit())
        if (bb.get() != 0)
            System.out.println("nonzero");
    System.out.println("i = " + i);
    bb.rewind();
    // Store and read a char array:

    // Store and read a short:
    bb.asShortBuffer().put((short) 471142);
    System.out.println(bb.getShort());
    bb.rewind();
    // Store and read an int:

    bb.rewind();
    // Store and read a long:
    bb.asLongBuffer().put(99471142);
    System.out.println(bb.getLong());
    bb.rewind();
    // Store and read a float:
    bb.asFloatBuffer().put(99471142);
    System.out.println(bb.getFloat());
    bb.rewind();
    // Store and read a double:
    bb.asDoubleBuffer().put(99471142);
    System.out.println(bb.getDouble());
