Given the code fragment:

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 str = "Java Rocks!";

         System.out.println(str.length() + " : " + str.charAt(10));

     }

}

What will be the result of compiling and executing Test class?

1. //Test.java

2. package com.udayan.oca;

3.  

4. import java.io.FileNotFoundException;

5.  

6. public class Test {

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

8.          try {

9.              System.out.println(1);

10.          } catch (NullPointerException ex) {

11.              System.out.println("ONE");

12.          } catch (FileNotFoundException ex) {

13.              System.out.println("TWO");

14.          }

15.          System.out.println("THREE");

16.      }

17. }

Consider below code: 

1. //Test.java

2. package com.udayan.oca;

3.  

4. import java.time.LocalDate;

5.  

6. public class Test {

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

8.          LocalDate joiningDate = LocalDate.parse("2006-03-16");

9.          System.out.println(joiningDate.withDayOfYear(29));

10.      }

11. }
