Basics of Java | Operators | Day 1

Problem:

Operators are symbols that perform operations on variables and values. For example, + is an operator used for addition, while * is also an operator used for multiplication.

Operators in Java can be classified into 6 types:

  • Arithmetic Operators
  • Assignment Operators
  • Relational Operators
  • Logical Operators
  • Unary Operators
  • Bitwise Operators

We will discuss about arithmetic operators and rest you can study from the references mentioned above.

Arithmetic Operators:

Arithmetic operators are used to perform arithmetic operations on variables and data. For example,

a + b;

Here, the + operator is used to add two variables a and b. Similarly, there are various other arithmetic operators in Java.

Operator       Operation
   +           Addition
   -           Subtraction
   *           Multiplication 
   /           Division
   %           Modulo Operation (Remainder after division)

Task:

You are given two integers as input a and b

You need to perform several tasks in the editor below:

  • In the variable named "add" store the sum of a and b.
  • In the variable named "sub" store the difference of a with b.
  • In the variable named "multi" store the multiplication of a and b.
  • In the variable named "div" store the division of a by b.

Solution: 

import java.lang.*;
import java.util.*;

public class Main {
    public static void main(String[] args) {
    
    /***Don't change anything here***/
        Scanner inp = new Scanner(System.in);
        int a = inp.nextInt();
        inp.nextLine();
        int b = inp.nextInt();
        inp.nextLine();
        inp.close();
    /*********************************/
    
    /*Perform the task here*/
        
        int add = a+b;
        int sub = a-b;
        int multi = a*b;
        int div = a/b;
        
    /***********************/
    
    /******Don't change anything here******/
        System.out.println(add);
        System.out.println(sub);
        System.out.println(multi);
        System.out.println(div);
    
    }
}
