 1. StringBuilder sb1 = new StringBuilder("123"); 2. String s1 = "123"; 3.  // insert code here 4. System.out.println(sb1 + " " + s1);

 class output { public static void main(String args[]) { String chars[] = {"a", "b", "c", "a", "c"}; for (int i = 0; i < chars.length; ++i) for (int j = i + 1; j < chars.length; ++j) if(chars[i].compareTo(chars[j]) == 0) System.out.print(chars[j]); } }
