# [Tutorial 4] : Operators in Java explained – Arithmetic and Relational

Okay so, In the previous post , I introduced about the different types of operators in Javaand also gave you a brief knowledge about the two main types of Operators used in Java that are – Arithmetic Operators and relational Operators.

Let us begin the tutorial for today with Arithmetic operators.

Let us begin the tutorial for today with Arithmetic operators.

## What are Arithmetic Operators in Java ?

Well , As we I already told you in the previous article that the operators used in Java to perform the basic addition , subtraction , multiplication , division and remainder operations are known as Arithmetic operators.

So , to summarise , Arithmetic operators are those which help you to perform the basic mathematical calculations in Java.

Now , I will give you the example of a Java program that is to be typed in BlueJ and this will make you clear about Arithmetic Operators.

So , to summarise , Arithmetic operators are those which help you to perform the basic mathematical calculations in Java.

Now , I will give you the example of a Java program that is to be typed in BlueJ and this will make you clear about Arithmetic Operators.

public class arithmetic_operators

{

public static void main()

{

int x = 25; //Value 25 assigned to variable x

int y = 7; //Value 7 assigned to variable ySystem.out.println(x+y);System.out.println(x-y);System.out.println(x*y);System.out.println(x/y);System.out.println(x%y);}}

**This program will produce the output as follows :-**

**32**

**18**

**175**

**3**

**4**

**Summarising Arithmetic operators –**To summarise all that we saw above , we can say that Arithmetic operators are used in doing calculations and there are five kinds of Arithmetic Operators namely Addition , Subtraction , Multiplication , Division , Modulus.

**ADDITION GIVES THE SUM OF NUMBERS**

SUBTRACTION GIVES THE DIFFERENCE

MULTIPLICATION GIVES THE PRODUCT

DIVISION GIVES QUOTIENT

MODULUS GIVES REMAINDER.

SUBTRACTION GIVES THE DIFFERENCE

MULTIPLICATION GIVES THE PRODUCT

DIVISION GIVES QUOTIENT

MODULUS GIVES REMAINDER.

**IMPORTANT –**You might be confused that “System.out.println” command is used to print something , so why is this program not printing the words as it is between the brackets. Well , It is because the words are printed only when they are enclosed between

**(“”)**

**NOTE**– You are advised to type this code in BlueJ and see the output.

Now, Let carry forward our discussion towards Relational Operators.

##
What** are Relational Operators in Java ?**

To be short and brief , We can quote that

**“Relational Operators in Java are the ones that are used to perform various comparisons between different kinds of operands.”**## What is an Operand –

Operand is a quantity on which an operation is done or on which an Operator is used.

Now , In order to make your concepts clearer , Here is an example of a program illustrating relational operators in Java.

public class relational_operators{public static void main(){int x = 25;int y = 7;System.out.println(x<y);System.out.println(x>y);System.out.println(x<=y);System.out.println(x>=y);System.out.println(x==y);System.out.println(x!=y);}}

**The output of this program is as follows :-**

**false**

**true**

**false**

**true**

**false**

**true**

So , We have seen that in the case of relational operators , the output is shown in the form of

**“TRUE” OR “FALSE”**Now I think you must be clear with the basic concept about Arithmetic and Relational Operators and you know how to use them.**You can comment down all your thoughts as well as queries and they will be resolved immediately.**
