Java Operators 

Java has different types of operators for different operations. They are as follows:

Arithmetic operators:

Arithmetic operators are used to perform arithmetic/mathematical operations.

Name	Operator	Example
Addition	+	a+b
Subtraction	-	a-b
Multiplication	*	a*b
Division	/	a/b
Modulus	%	a%b
Increment	++	a++ or b++
Decrement	--	a-- or b--

 

Assignment operators:

These operators are used to assign values to variables.

Name	Operator	Evaluated As
Assignment	=	a=b
Addition assignment	+=	a+=b    or    a=a+b
Subtraction assignment	-=	a-=b    or    a=a-b
Multiplication assignment	*=	a*=b    or    a=a*b
Division assignment	/=	a//=b    or    a=a//b
Modulus assignment	%=	a%=b    or    a=a%b
Bitwise AND assignment	&=	a&=b    or    a=a&b
Bitwise inclusive OR assignment	|=	a|=b    or    a=a|b
Bitwise exclusive OR assignment	^=	a^=b    or    a=a^b
Right Shift assignment	>>=	a>>=b    or    a=a>>b
Left Shift assignment	<<=	a<<=b    or    a=a<<b

 

Bitwise operators:

Bitwise operators are used to deal with binary operations.

Name	Operator	Example
Bitwise AND	&	a & b
Bitwise OR	|	a | b
Bitwise NOT	~	~a
Bitwise XOR	^	a ^ b
Bitwise right shift	>>	a>>
Bitwise left shift	<<	b<<
Unsigned right shift	>>>	a>>>

 

Comparison operators:

These operators are used to compare values.

Name	Operator	Example
Equal	==	a==b
Not Equal	!=	a!=b
Less Than	<	a>b
Greater Than	>	a<b
Less Than or Equal to	<=	a>=b
Greater Than or Equal to	>=	a<=b

 

Logical operators:

These operators are used to deal with logical operations.

Name	Operator	Example
AND	&&	a && b
OR	||	a || b
NOT	!	! (a=2 or b=3)

 

Other operators:

A. instanceof operator:

This operator checks if an object is an instance of class.

Example:

class Main {
    public static void main(String[] args) {
  
        Integer number = 5;
        boolean res;
    
        if (res = number instanceof Integer){
            System.out.println("number is an object of Integer. Hence: " + res);
        } else {
            System.out.println("number is not an object of Integer.Hence: " + res);
        }
    }
}

Output:

number is an object of Integer. Hence: true

 

B. Conditional operator:

It is used in a single line if-else statement.

Example:

class Main {
    public static void main(String[] args) {
  
        Integer number = 3;
        String res;
    
        res = (number > 5) ? "number greater than five" : "number lesser than five";
        System.out.println(res);
    }
}

Output:

number lesser than five
