   public static void main (String args [] ){ 
      StringBuilder sb = new StringBuilder ("12345678"); 
      sb .setLength (5); 
      sb .setLength (10); 
      System.out.println (sb .length ()); 
    } 
}

Select 1 option

  • A. It will print 5.
  • B. It will print 10.
  • C. It will print 8.

If you do System.out.println (sb); it will indeed print 12345 but the length will be 10.
