Example:

// Java program to demonstrate the example 
// of Object handleGetObject(String key_ele)  method 
// of ListResourceBundle 

import java.util.*;

// Instantiates a class that extends
// ListResourceBundle 
class HandleGetObjectOfLRB extends ListResourceBundle {
 // By using getContent() method is to
 // get the contents in the form of 
 // 2D objects
 protected Object[][] getContents() {
  return new Object[][] {
   {
    "10",
    "C"
   }, {
    "20",
    "C++"
   }, {
    "30",

  // GetKeys
  HandleGetObjectOfLRB get_ob = new HandleGetObjectOfLRB();
