// Java program to demonstrate the example 
// of Object[][] getContents()  method of  
// ListResourceBundle 

import java.util.*;

// Instantiates a class that extends
// ListResourceBundle 
class GetContents extends ListResourceBundle {
 // By using getContent() method is to
 // get the contents in the form of 
 // 2D objects
 protected Object[][] getContents() {
  return new Object[][] {
   {
    "10",

    "20",
    "C++"
   }, {

}

public class Main {
 public static void main(String[] args) {
  // Instantiates an object of
  // GetContents
  GetContents get_c = new GetContents();

  // Display the value for the
