Operators in Java Programming Language

Java Language Operators Definition: Java language operators is a fundamental components of Java programming that allow programmer to perform operations on variables and values. Operators can be used to perform arithmetic calculations, compare values, assign data, logical conditions. Understanding Java language operators with beginners as well as experienced programmers, because operators are used in almost every programming languages. In this complete guide you will learn all types of Java operators including arithmetic, relational, logical, assignment, ternary, bitwise, conditional, and special operators, explained simple examples.

Java Arithmetic Operators

Arithmetic Operator: Java arithmetic operator can be used to mathematical or logical operation perform like addition, subtraction, multiplication and more. It can be very most important operator in computer programming languages.

Types of Arithmetic Operators in Java

Symbols	Operation	Example
(+)	Addition	(a+b)=> (5+6)=>9
(-)	Subtraction	(a-b)=> (8-3)=>5
(*)	Multiplication	(a*b)=> (5*6)=>30
(/)	Division	(a/b)=> (5/2)=>2.5
(%)	Modulus	(a%b)=> (5%2)=>1

Arithmetic Operators in Java Program

import java.util.Scanner; public class Arithmetic { public static void main(String[] args) { int x,y; Scanner s=new Scanner(System.in); System.out.print("Enter First Number:"); x=s.nextInt(); System.out.print("Enter Second Number:"); y=s.nextInt(); System.out.println("Addition of x+y:"+(x+y)); System.out.println("Substraction of x-y:"+(x-y)); System.out.println("Multiplication of x*y:"+(x*y)); System.out.println("Division of x/y:"+(x/y)); System.out.println("Modulus of x%y:"+(x%y)); } } ============OUTPUT============ Enter First Number: 6 Enter Second Number: 3 Addition of x+y:9 Substraction of x-y:3  Multiplication of x*y:18 Division of x/y:2  Modulus of x%y:0

Relational Operators in Java Language

Relational Operator: A relational operators can be used to performed operation two values compression and results provide true and false. Relational operators compare two variables expression and check relationship than provide results.

Types of Relational Operators

Symbols	Operation	Example
(==)	Equal To	(a==b)
(>)	Greater Than	(a>b)
(<)	Less Than	(a<b)
(>=)	Greater Than Or Equal To	(a>=b)
(<=)	Less Than Or Equal To	(a<=b)
(!=)	Not Equal To	(a!=b)

Relational Operators Program in Java

import java.util.Scanner; public class Relational { public static void main(String[] args) { int x,y; Scanner s=new Scanner(System.in); System.out.print("Enter First Number:"); x=s.nextInt(); System.out.print("Enter Second Number:"); y=s.nextInt(); System.out.println("Equal To x==y:"+(x==y)); System.out.println("Greater Than x>y:"+(x>y)); System.out.println("Less Than x<y:"+(x<y)); System.out.println("Greater than or Equal To x>=y:"+(x>=y)); System.out.println("Less Than or Equal To x<=y:"+(x<=y)); System.out.println("Not Equal To x!=y:"+(x!=y)); } } ============OUTPUT============ Enter First Number: 9 Enter Second Number: 4 Equal To x==y: false Greater Than x>y: true Less Than x<y: false Greater than or Equal To x>=y: true Less Than or Equal To x<=y: false Not Equal To x!=y: true

Logical Operators in Java

Logical Operator: A logical operators can be used compare two variables and perform logical operations. If the logical condition is true than return 1 and logical condition is false than return 0.

Logical AND Operator: A logical AND operator condition is a both condition are true than result are true. If the any one condition are false then return false.

Logical AND Operator in Java

import java.util.Scanner; public class login { public static void main(String[] args) { String username="jiocoding" String password="12345"; char password[100]="12345"; String user; String pwd; Scanner s=new Scanner(System.in); System.out.print("Enter Username:"); user=s.next(); System.out.print("Enter Password:"); pwd=s.next(); if(user.equals(username)&&pwd.equals(password)){ System.out.println("Login Successfully..."); } else{ System.out.println("Username or Password invalid..."); } } } ============OUTPUT============ Enter Username: jiocoding Enter Password: 12345 Login Successfully

Logical OR Operator: A logical OR operator can be used to anyone condition are true than both condition are true. If one condition are false than return true.

Logical OR Operators in Java Program

import java.util.Scanner; public class login { public static void main(String[] args) { String username="jiocoding" String password="12345"; char password[100]="12345"; String user; String pwd; Scanner s=new Scanner(System.in); System.out.print("Enter Username:"); user=s.next(); System.out.print("Enter Password:"); pwd=s.next(); if(user.equals(username)||pwd.equals(password)){ System.out.println("Login Successfully..."); } else{ System.out.println("Username or Password invalid..."); } } } ============OUTPUT============ Enter Username: jiocoding Enter Password: 12345654 Login Successfully

Logical NOT Operator: A logical NOT operator reverses the state means if the condition is true it returns false and if the condition is false it returns true.

How Many Types of Logical Operators

Symbols	Operation	Example
(&&)	Logical AND	(a&&b)
(||)	Logical OR	(a||b)
(!)	Logical NOT	(a!=b)

Logical Operators in Java Program

import java.util.Scanner; public class login { public static void main(String[] args) { String username="jiocoding" String password="12345"; char password[100]="12345"; String user; String pwd; Scanner s=new Scanner(System.in); System.out.print("Enter Username:"); user=s.next(); System.out.print("Enter Password:"); pwd=s.next(); if(user.equals(username)||pwd.equals(password)){ System.out.println("Login Successfully..."); } else{ System.out.println("Username or Password invalid..."); } } } ============OUTPUT============ Enter Username: JIOCODING Enter Password: 12345 Username or Password Invalid

Assignment Operators in Java

Assignment Operator: A Java assignment operator can be used to assign the value of an right side and variable on the left side. 

Types of Assignment Operators

Symbols	Operation	Example
(=)	(a=b)	(a=b)
(+=)	(a+=b)	(a=a+b)
(-=)	(a-=b)	(a=a-b)
(*=)	(a*=b)	(a=a*b)
(/=)	(a/=b)	(a=a/b)
(%=)	(a%=b)	(a=a%b)

Assignment Operator in Java program

import java.util.Scanner; public class Relational { public static void main(String[] args) { int x,y; Scanner s=new Scanner(System.in); System.out.print("Enter First Number:"); x=s.nextInt(); System.out.print("Enter Second Number:"); y=s.nextInt(); System.out.println("Assignment Addition of x+=y"+x); ============OUTPUT============ Enter First Number: 8 Enter Second Number: 8 Assignment Addition of x+=y: 16

Bitwise Operator Definition

Bitwise Operator: A Java bitwise operator can be used to perform individual operation bits on integers data. Bitwise operators are used to binary operations performed.

Types of Bitwise Operators

Symbols	Operation	Example
(&)	Bitwise AND	(a&b)
(|)	Bitwise OR	(a|b)
(<<)	Bitwise Shift Left	(a<<b)
(>>)	Bitwise Shift Right	(a>>b)

Java Bitwise Operators

import java.util.Scanner; public class Relational { public static void main(String[] args) { int x,y; Scanner s=new Scanner(System.in); System.out.print("Enter First Number:"); x=s.nextInt(); System.out.print("Enter Second Number:"); y=s.nextInt(); System.out.println("Bitwsie AND Operator:"+(x&y)); System.out.println("Bitwsie OR Operator:"+(x|y)); System.out.println("Bitwise Shift Left Operator:"+(x<<2)); System.out.println("Bitwsie Shift Right Operator:"+(x>>2)); } } ============OUTPUT============ Enter First Number: 5 Enter Second Number: 3 Bitwise AND Operator: 1 Bitwise OR Operator:7 Bitwise Shift Left Operator: 20 Bitwise Shift Right Operator:1

Increment and Decrement Operators

Increment Operator: increment or decrement operators can be used to increase 1 value and decrement 1 value. Mostly increment operator commonly used to loops in java.

Types of Increment and Decrement Operators

Symbols	Name	Function	Example
(++)	Increment	It increment the value 1	++a
(--)	Decrement	It Decrement the value 1	--a

Increment Operators in Java Program

public class Jiocoding { public static void main(String[] args) { int x=8; System.out.println("Increment Operator ++x:"+(++x)); } ============OUTPUT============ Increment Operator of ++x:9

Decrement Operators in Java Program

public class Jiocoding { public static void main(String[] args) { int x=8; System.out.println("Decrement Operator --x:"+(--x)); } ============OUTPUT============ Increment Operator of x++:7

Ternary Operator Definitions

Ternary Operators: A conditional operators can be used to one line operators or ternary operators because it can be used to three operands values.

Ternary Operators in Java Program

public class Jiocoding { public static void main(String[] args) { System.out.println(10 < 5 ? "Welcome" : "Jiocoding"); } ============OUTPUT============ Jiocoding
