May 22, 2023 · We will be creating a basic calculator in java using the nested if/else statements which can perform operations like addition, subtraction, multiplication, division, and modulo of any two numbers. We will be defining the numbers as an integer but if you want the decimal side of numbers as well feel

Java program example for making a simple Calculator: import java.util.Scanner; public class Calculator { public static void main(String args[]) { float a, b, res; char select, ch; Scanner scan = new Scanner(System.in); do { System.out.print("(1) Addition\n"); System.out.print("(2) Subtraction\n"); System.out.print("(3) Multiplication\n ...

Start off by declaring a public Calculator class and then inside of it, a main method, exactly like shown in the picture. In Java, a class is simply an object which holds information. In our case, the object we're building is a calculator so we have named it as such. A method is a process which performs a certain task.

To understand this example, you should have the knowledge of the following Java programming topics: class Main { public static void main(String[] args) { char operator; Double number1, number2, result; // create an object of Scanner class . Scanner input = new Scanner(System.in); // ask users to enter operator .
