Menu Driven Java Program to Perform Arithmetic Operators

In this example, you learn about menu driven Java program to perform arithmetic operators. basically, it is a menu driven mini calculator with all arithmetic operators in java. 

Program:

import java.util.*; 
class mini_calculator {
 static int a=10;
  public static int add(int x,int y)
  {
   return x+y;
  }
  public static int sub(int x,int y)
  {
   return x-y;
  }
  public static int multi(int x,int y)
  {
   return x*y;
  }
  public static float divide(int x,int y)
  {
   return x/y;
  }
 public static void main(String args[])
 {
  Scanner s=new Scanner(System.in); 
  int x,y,ch,w;
  System.out.println(a); 
  float w1;
   while (true){
    System.out.println("1. Addition"); 
    System.out.println("2. Subtraction"); 
    System.out.println("3. Multipllication");
    System.out.println("4. Division");
    System.out.println("Enter Your choice:-");
    ch=s.nextInt();
    switch (ch){ 
    case 1:
     System.out.println("Enter Numbers:-");
     x=s.nextInt();
     y=s.nextInt();
     w=add(x,y); 
     System.out.println(w); 
     break;
    case 2:
     System.out.println("Enter Numbers:-"); 
     x=s.nextInt();
     y=s.nextInt();
     w=sub(x,y); 
     System.out.println(w);
     break;
    case 3:
     System.out.println("Enter Numbers:-"); 
     x=s.nextInt();
     y=s.nextInt(); 
     w=multi(x,y); 
     System.out.println(w);
     break;
    case 4:
        System.out.println("Enter Numbers:-");
     x=s.nextInt();
     y=s.nextInt(); 
     w1=divide(x,y); 
     System.out.println(w1); 
     break;
    case 5: break;
    }
   }
  }
 }

Program Output:

  C:\jdk-12.0.2\bin>java mini_calculator 10
  1.Addition
  2.Subtraction
  3.Multipllication
  4.Division
  Enter Your choice:- 2
  Enter Numbers:- 13
  3
  10
  1.Addition
  2.Subtraction
  3.Multipllication
  4.Division
  Enter Your choice:- 4
  Enter Numbers:- 2
  2
  1.0

This is all about menu driven Java program to perform arithmetic operators using switch case. 

Happy Coding 😊
