Examples of java.nio.CharBuffer.compareTo()

java.nio.CharBuffer.compareTo()
Compare the remaining chars of this buffer to another char buffer's remaining chars. @param otherBuffer Another char buffer @return a negative value if this is less than other; 0 ifthis equals to other; a positive value if this is greater than other @exception ClassCastException If other is not a char buffer

    CharBuffer other = CharBuffer.allocate(buf.capacity());
    other.put(buf);
    other.clear();
    buf.clear();
    assertEquals(0, buf.compareTo(other));
    assertEquals(0, other.compareTo(buf));
    buf.position(1);
    assertTrue(buf.compareTo(other) > 0);
    assertTrue(other.compareTo(buf) < 0);
    other.position(2);
    assertTrue(buf.compareTo(other) < 0);
