Arithmetic operator in Java Language

Arithmetic Operator: A arithmetic operation is a used mathematical operation performed.

It is many operations performed like addition, subtraction, multiplication, and division.

👉C Operators 

👉 Python Operators

Example of Arithmetic operator

Addition:a+b or 10+10=20
Here a is operands value (+) Addition is operator and b is operands. It can be used for additional operations performed.

Subtraction:a-b or 20-10=10
Here a is operands value (-) Subtraction sign is operator and b is operands. It can be used as Subtraction operations performed.

Multiplication:a*b or 10*10=100
Here a is operands value (*) Multiplication sign is operator and b is operands. It can be used Multiplication operations performed.

Division:a/b or 10/5=2
Here a is operands value (/) Division sign operator and b is operands. It can be used for Division operations performed.

Modules: a%b or 10%3=1
Here a is operands value (%) Modules sign operator and b is operands. It can be used Modules operations performed.

How To Use Arithmetic Operator in Java?

class icoderweb

{

public static void main(String[] args()

{

System.out.println("Modulus:"+(a%b));

}

} 

*****OUTPUT*****

Addition:41

Relational Operator in Java Language

Relational Operator: A Java Relational operator has used the comparison of the two operands. It can be using equal operands and condition check in this operator. Relational operator very most and useful operator.

Java Relational Operator Table

Sign.      Operation.         Example

(==)           Equal To              (a+b)

(!=)           Not Equal To       (a-b)   

(>)            Greater Than       (a*b)

(<)             Less Than           (a/b)

(>=)   Grater than Or Equal  (a%b)

(<=)   Less Than Or  Equal    (a%b)

class icoderweb

{

public static void main(String[] args()

{

int a=10;

int b=10;

if(a==b)

{

System.out.println("value of a and b are equal");

}

if(a!=100)

{

System.out.println("value not equal to");

}

if(a>5)

{

System.out.println("value a is grater than 5");

}

if(a<50)

{

System.out.println("value a is less than 50");

}

if(a>=10)

{

System.out.println("value a is grater than or equal to 10");

}

if(a<=10)

{

System.out.println("value a is less than or equal to 10");

}

}

*****OUTPUT*****

value of a and b are equal

value not equal to

value a is greater than 5

value a is less than 50

value a is greater than or equal to 10

value a is less than or equal to 10

Logical Operator in Java Language

Java Logical Operators: Java Language provides three logical operators. logical Operator tests more than one condition to make decisions.

Types of Java Logical Operator

1.&& AND

2.|| OR

3.!  NOT

1. AND Operator can be used decisions are two values.AND Operator two values are True AND Operator return True.

But two values are anyone False AND Operator return False.

2. OR operator performs a logical condition on two expressions. if or Operator can be two expressions are True OR Operator return true.

But any of the expressions are False OR Operator return True.

3. NOT operator is very easy Operator. it can be used condition are True NOT Operator returns False and condition are False NOT Operator returns True.

class icoderweb

{

public static void main(String[] args()

{

int x=10;

int y=60;

int z=40;

if(x>y&&x>z)

System.out.println("x is grater");

if(y>x&&y>z)

System.out.println("y is grater");

if(z>x&&z>y)

} 

}

*****OUTPUT*****

y is grater

Java Assignment Operator Table 

Sign.        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)

How To Use Assignment Operator in Java?

class icoderweb

{

public static void main(String[] args()

{

int a=10,b=5;

a+=b;

System.out.println("Assignment Addition:"+a);

int a1=10,b1=5;

a1-=b1;

System.out.println("Assignment Subtraction:"+a1);

int a2=10,b2=5;

a2*=b2;

System.out.println("Assignment multiplication:"+a2);

int a3=10,b3=5;

a3/=b3;

System.out.println("Assignment Division:"+a3);

int a4=10,b4=5;

a4%=b4;

System.out.println("Assignment Division:"+a4);

}

}

*****OUTPUT*****

Assignment Addition:15

Assignment Subtraction:5

Assignment Multiplication:50

Assignment Division:2

Assignment Moduls:1

Increment Operator in  Java Language

Increment Operators :Increment Operators are useful operators generally used.like++x and x++ means x=x+1.
pre-increment first add one to the operand and then the result is assigned to the variable on the left.
post-increment first assigns the value to the variable on the left and then increments the operand.

How To Use Increment Operator in Java?

class icoderweb

{

public static void main(String[] args()

{

int a=5;

int b=10;

System.out.println("pre-increment operator:+(++a));

System.out.println("post-increment operator:+(b+1));

}

}

*****OUTPUT*****

pre-increment operator:6

post-increment operator:11

Decrement Operator in  Java Language

Java Decrement: A Decrement Operator used the decrease the value. like --x and x--.

Pre-decrement first less one to the operands and then the result is assigned to the variable on the left.

Post-decrement first assigns the value to the variables on the left and then decrements the operands.

class icoderweb

{

public static void main(String[] args()

{

int a=5;

int b=10;

System.out.println("pre-decrement operator:+(--a));

System.out.println("post-decrement operator:+(b-1));

}

*****OUTPUT*****

pre-decrement operator:4

post-decrement operator:9

Bitwise Operator in  Java Language

Java Bitwise Operator: A Bitwise operator is an operation performed on the data bit level. the bitwise operator is also shifted bit right to left.

Note: Bitwise operators are not allowed to float and double.

Java Bitwise Operator Table 

Sign.        Operation.         Example

(&)           Bitwise AND         (a&b)

(|)             Bitwise OR             (a|b)  

 
(<<)         Bitwise LEFT        (a<<2)

(>>)        Bitwise RIGHT      (a>>2)
