    System.out.println("sb = " + sb);
    System.out.println("Length = " + sb.length());
    System.out.println("Capacity = " + sb.capacity());

    sb.setLength(2);/*from ww  w  .j a  v  a  2  s  . c om*/

    System.out.println("sb = " + sb);
    System.out.println("Length = " + sb.length());

}

From source file:MainClass.java
