Given the code fragment:

Given code of Thought.java file:

1. public class Thought {

2.     /*INSERT*/ {

3.         System.out.println("All is well");

4.     }

5. }

Which 3 options, if used to replace /*INSERT*/, will compile successfully and on execution will print "All is well" on to the console?

2. package com.udayan.oca;

3.  

4. public class Test {

5.     public static void main(String[] args) {

6.         StringBuilder sb = new StringBuilder(100);

7.         System.out.println(sb.length() + ":" + sb.toString().length());

8.     }

9. }
