import java.util.Scanner; public class Calculate { public static void main(String[] args) { int m, n, opt, add, sub, mul; double div; Scanner s = new Scanner(System.in); System.out.print("Enter first number:"); m = s.nextInt(); System.out.print("Enter second number:"); n = s.nextInt(); while(true) { System.out.println("Enter 1 for addition"); System.out.println("Enter 2 for subtraction"); System.out.println("Enter 3 for multiplication"); System.out.println("Enter 4 for division"); System.out.println("Enter 5 to Exit"); opt = s.nextInt(); switch(opt) { case 1: add = m + n; System.out.println("Result:"+add); break; case 2: sub = m - n; System.out.println("Result:"+sub); break; case 3: mul = m * n; System.out.println("Result:"+mul); break; case 4: div = (double)m / n; System.out.println("Result:"+div); break; case 5: System.exit(0); } } } } Try this code. Thanks

import java.util.Scanner; public class JavaProgram { public static void main(String args[]) { int first, second, add, subtract, multiply; float devide; Scanner scanner = new Scanner(System.in); System.out.print("Enter Two Numbers : "); first = scanner.nextInt(); second = scanner.nextInt(); add = first + second; subtract = first - second; multiply = first * second; devide = (float) first / second; System.out.println("Sum = " + add); System.out.println("Difference = " + subtract); System.out.println("Multiplication = " + multiply); System.out.println("Division = " + devide); } } Output :- Enter Two Numbers : 12 5 Sum = 17 Difference = 7 Multiplication = 60 Division = 2.4 IF IT HELPS MARKS AS ANSWER

Hello lfeoluwa, Here is the complete program, import java.util.Scanner; public class Exercise6 { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Input first number: "); int num1 = in.nextInt(); System.out.print("Input second number: "); int num2 = in.nextInt(); System.out.println(num1 + " + " + num2 + " = " + (num1 + num2)); System.out.println(num1 + " - " + num2 + " = " + (num1 - num2)); System.out.println(num1 + " x " + num2 + " = " + (num1 * num2)); System.out.println(num1 + " / " + num2 + " = " + (num1 / num2)); System.out.println(num1 + " mod " + num2 + " = " + (num1 % num2)); } } If you have any query feel free to contact me.

Hey Ifeoluwa Omobolanle, you can make the program for addition, subtraction, and multiplication of two numbers using different ways in Java. I am giving you the solution using switch...case: import java.util.Scanner; public class Calculate { public static void main(String[] args) { int a, b, choice, add, sub, mul; Scanner s = new Scanner(System.in); System.out.print( "Enter first number:" ); a = s.nextInt(); System.out.print( "Enter second number:" ); b = s.nextInt(); while ( true ) { System.out.println( "Enter 1 for addition" ); System.out.println( "Enter 2 for subtraction" ); System.out.println( "Enter 3 for multiplication" ); System.out.println( "Enter 4 to Exit" ); choice = s.nextInt(); switch (choice) { case 1 : add = a + b; System.out.println( "Result:" +add); break ; case 2 : sub = a - b; System.out.println( "Result:" +sub); break ; case 3 : mul = a * b; System.out.println( "Result:" +mul); break ; case 4 : System.exit( 0 ); } } } } Hope you find this answer useful.
