Operators in Java

What is Operator?

• Operators are used to perform a operation on operands.

Types of Operators:

• Arithmetic Operator
• Assignment Operator
• Relational Operator
• Logical Operator
• Unary Operator
• Ternary Operator
• Shift Operator
• Bitwise Operator

Arithmetic Operator:

Operator	Description
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus (Remainder)

class Arithmetic
{

public static void main (String[] args)
{

int a=100;
int b=20;

System.out.println("Addition:"+(a+b));
System.out.println("Sub:"+(a-b));
System.out.println("Multiply:"+(a*b));
System.out.println("Divide:"+(a/b));
System.out.println("Modulo:"+(a%b));

}

}

Addition:120
Sub:80
Multiply:2000
Divide:5
Modulo:0

---

Assignment Operator:

• Used to assign values to a variable.

Operator	Example
=	a = 10
+=	a += 5
-=	a -= 5
*=	a *= 5
/=	a /= 5
%=	a %= 5

class Assignment
{

public static void main (String[] args)
{

int a;
System.out.println("Assigning:"+(a = 10));
System.out.println("Add:"+(a += 20));
System.out.println("Sub:"+(a -= 10));
System.out.println("Multiply:"+(a *= 10));
System.out.println("Divide:"+(a /= 10));
System.out.println("Modulo:"+(a %= 3));

}
}

Assigning:10
Add:30
Sub:20
Multiply:200
Divide:20
Modulo:2

---

Relational Operator:

• Used to compare two values.

Operator	Meaning
==	Equal to
!=	Not Equal to
>	Greater Than
<	Less Than
>=	Greater Than or Equal
<=	Less Than or Equal

class Relational
{

public static void main (String[] args)
{

int a=10;
int b=30;

System.out.println("Equal to:"+(a == b));
System.out.println("Not Equal to:"+(a != 20));
System.out.println("Greater than:"+(a > b));
System.out.println("Less than:"+(a<b));
System.out.println("Greater than or Equal to:"+(a >= b));
System.out.println("Greater than or Equal to:"+(a <= b));

}

}

Equal to:false
Not Equal to:true
Greater than:false
Less than:true
Greater than or Equal to:false
Greater than or Equal to:true

---

Logical Operator:

class Logical
{

public static void main (String[] args)
{

int a=10;
int b=30;

System.out.println("AND:"+((a > b) && (a != 20)));
System.out.println("OR:"+((a == 20) || (b>a)));
System.out.println("NOT:"+(a != b));
}

}

AND:false
OR:true
NOT:true

---

Unary Operator:

Operator	Meaning
+	Unary Plus
-	Unary Minus
++	Increment
--	Decrement
!	Logical NOT

class Unary
{

public static void main (String[] args)
{

int a=10;
int b=30;

System.out.println("Unary Plus:"+(a+b));
System.out.println("Unary Minus:"+(a-b));
System.out.println("Increment:"+(++a));
System.out.println("Decrement:"+(a--));
System.out.println("Logical Not:"+(!true));
}

}

Unary Plus:40
Unary Minus:-20
Increment:11
Decrement:11
Logical Not:false

---

Ternary Operator:

A shortcut for if-else.

Syntax

condition ? value1 : value2;

class Ternary
{

public static void main (String[] args)
{

int a=10;
int b=30;

String result = (a>b ? "A is Larger" : "B is Larger");

System.out.println("Which number is Larger?"+result);
}

}

Which number is Larger? B is Larger
