Question

Consider the following code segment. public class KaBoom { public int b; public void m1 () {//Your code goes here } public void m2 (KaBoom k) { System, out. print In (k. b); } } Complete the method body of m1 () indicated by the comment line. The m1 () method simply calls the m2 () method by passing in the current KaBoom object variable to m2 ().

Java question

Answer 1

//Main_KaBoom.java

import java.io.*;
import java.util.*;

class KaBoom{
   public int b;

   //Default Constructor
   KaBoom(){}

   //Parameterised Constructor
   KaBoom(int b){
       this.b = b;  
   }
  
   //User code
   public void m1(){

       KaBoom obj = new KaBoom(b);
       m2(obj);
   }

   public void m2(KaBoom k){
       System.out.println(k.b);
   }
}

//Test code
public class Main_KaBoom{

   public static void main(String args[]){

       KaBoom k = new KaBoom();
       k.b = 30;
       k.m1();
   }
}

//Output:

//Main_KaBoom.java import java.io.*: import java.util.*: class KaBoom{ public int b: //Default Constructor KaBoom(){} //Parameterised Constructor KaBoom(int b){ this.b = b: } //User code public void m1(){ KaBoom obj = new KaBoom(b): m2(obj): } public void m2(KaBoom k){ System.out.println(k.b): } } //Test code public class Main_KaBoom{ public static void main(String args[]){ KaBoom k = new KaBoom(): k.b = 30: k.m1(): } } //Output: //Main_KaBoom.java import java.io.*: import java.util.*: class KaBoom{ public int b: //Default Constructor KaBoom(){} //Parameterised Constructor KaBoom(int b){ this.b = b: } //User code public void m1(){ KaBoom obj = new KaBoom(b): m2(obj): } public void m2(KaBoom k){ System.out.println(k.b): } } //Test code public class Main_KaBoom{ public static void main(String args[]){ KaBoom k = new KaBoom(): k.b = 30: k.m1(): } } //Output: C: \air > javac Main_KaBoom.
