Question

Show some examples of a few Parameters and Objects problems in java language and the solution code. Need more practice as a new learner

Answer 1

Hey here is the answer feel free to ask anything realted to this question

I am comfortable in java if you need a Solution in C++ then COMMENT  ME i will provide you a Solution in c++ language.

First of all you need to under what is object?

object ->*Object is a instance of class

* object occupy memory

* object is a real world entity

* Object consist of ->

1 -> identity (name)

2-> state

2-> Behaviours

Object syntax->

classname objectname

example->  Animal dog=new Animal(); // we are creating an object and new keyword is used for creating an object

Paremeters -> The argument passed in a method is called method

void man( int a , int b)

Example 1->

package com;
public class World {
  
  
  
   public void hello(int x, int y)// int ,int b is a parameters and we use void because we are not return any value
   {
      
       int m=x-y;
       System.out.println(m);
      
   }
  
  
  
   public static void main(String[] args) {
       // TODO Auto-generated method stub
      

       World w=new World();// w is a object name and Word is a class name
       w.hello(20,10); // we are passing a value in a function
      
  
      
      
   }

}

Example 2->

package com;
public class World {
  
  
  
   public int hello(int x, int y)// int x ,int b is a parameters and we use int because this function return a value which of off integer type
   {
      
       int m=x-y;
       return m;
      
   }
  
  
  
   public static void main(String[] args) {
       // TODO Auto-generated method stub
      

       World w=new World();// w is a object name and Word is a class name
       int x=w.hello(20,10); // we are passing a value in a function
       System.out.println(x); // return value store in a variable x and then print it
      
  
      
      
   }

}
