Consider below code of Test.java file:1. package com.sampleproject.oca;2.  3. class Super {4.     public String num = "10"; //Line n15. }6.  7. class Sub extends Super {8.     protected int num = 20; //Line n29. }10.  11. public class Test {12.     public static void main(String[] args) {13.         Super obj = new Sub();14.         System.out.println(obj.num += 2); //Line n315.     }16. }What will be the result of compiling and executing above code?

Which two statements are true? (Choose two.)

What will be the result of compiling and executing Test class?package com.udayan.oca; public class Test {     public static void main(String[] args) {         String str1 = " ";         boolean b1 = str1.isEmpty();         System.out.println(b1);         str1.trim();         b1 = str1.isEmpty();         System.out.println(b1);     }}

Given:and the code fragment:What is the result?

Given:And the code fragment:Which code fragment, when inserted at line 14, enables the code to print Mike Found?
