Ternary and Bitwise operators.

In this article,Ternary and Bitwise operators is explained in detail with examples.

It is also known as a conditional operator.Ternary means three values.The operator is '?'.

Syntax

(expre1)?(expre2):(expre3)

If expre1 is true then expre2 is executed. If expre1 is false then expre3 is executed.

//program related to Ternary and Bitwise operators-ternary operator.

class TernaryOperatorDemo

{

public static void main(String args[])

{

int a=10,b=20;

System.out.println("Using ternary operator:");

int c=(a>b)?a:b;

System.out.println("Biggest of two numbers is:"+c);

int c=(a<b)?(a=a+10):(b=b+10);

System.out.println("A is: "+a);

System.out.println("B is: "+b);

System.out.println("C is: "+c);

}

Output

Using First integer values.

Using the second integer value.

Bit wise Operator.

These operators are used to perform operations on bit levels of a given numbers ( Binary representation of a number).

* These operators work only on integer values. (From topic Ternary and Bitwise operators)

The operators are

& ---Bitwise AND
| ---Bitwise OR
^ ---Bitwise XOR
~ ---Bitwise Compliment
<< --Bitwise Left-shift
>> --Bitwise Right-shift
>>>-Bitwise Right shift with zero-fill.

{

int x=10,y=18;

System.out.println("x is: "+x);

System.out.println("y<<2 is: "+(y<<2));

System.out.println("x>>2 is: "+(x>>2));

System.out.println("y>>2 is: "+(y>>2));

x=-11;y=-19;

System.out.println("x<<2 is: "+(x<<2));

System.out.println("y<<2 is: "+(y<<2));

System.out.println("x>>2 is: "+(x>>2));

x=18;y=-11;

System.out.println("x>>2 is: "+(x>>2));

System.out.println("y>>2 is: "+(y>>2));

}

Output

x is: 10

y is: 18

x&y is: 2

x/y is: 0

x^y is: 24

~x is: -11

~y is: -19

x is: 10

y is: 18

x<<2 is: 40

y<<2 is: 72

x>>2 is: 2

y>>2 is: 4

x<<2 is: -44

y<<2 is: -76

x>>2 is: -3

y>>2 is: -5

x>>2 is: 4

y>>2 is: -3
