Operators in java
Operator is used to perform some operation.In java programming there are seven operators available.
Types of operator
- Arithmetic operator
- Relational operator
- Assignment operator
- Boolean Logiacal operator
- Bitwise operator
- Unary operator
- Ternary operator
1. Arithmetic operator
Arithmetic operator used to perform the basic mathematics operation.
| Operator | Example | Explain |
|---|---|---|
| + | x+y | Add the number |
| - | x-y | Subtract the number |
| * | x*y | multiplying the number |
| / | x/y | dividing the number |
| % | x%y | remainder of the number |
Example
public class Main
{
public static void main(String[] args)
{
int x = 5;
int y = 4;
System.out.println(x+y);
}
}
Output
9
2. Relational operator
It is also called the comparison operator.It used to compare the value.
| Operator | Example | Explain |
|---|---|---|
| == | x==y | To compare the x and y values are equal. |
| != | x!=y | To compare the x and y values are not equal. |
| < | x<y | To compare x values is greater than y values. |
| > | x>y | To compare x values is lesser than y values. |
| <= | x<=y | To compare x values is greater than or equal in y values. |
| >= | x>=y | To compare x values is lesser than or equal in y values. |
Example
public class Main
{
public static void main(String[] args)
{
int x = 5,y = 4;
System.out.println(x==y);
System.out.println(x!=y);
System.out.println(x<y);
System.out.println(x>y);
System.out.println(x<=y);
System.out.println(x>=y);
}
}
output
false true false true false true
3. Assignment operator
Assignment operator used to assign the value.But it's assign the value like , if x+=5 means x=x+5.
| Operator | Example | How assign |
|---|---|---|
| += | x+=10 | x=x+10 |
| -= | x-=10 | x=x-10 |
| *= | x*=10 | x=x*10 |
| /= | x/=10 | x=x/10 |
| %= | x%=10 | x=x%10 |
| &= | x&=10 | x=x&10 |
| |= | x|=10 | x=x|10 |
| ^= | x^=10 | x=x^10 |
| >= | x>>=10 | x=x>>10 |
| <<= | x<<=10 | x=x<<10 |
Example
public class Main { public static void main(String[] args) { int x = 1; x += 10; //x=x+10 => 1+10 System.out.print(x); //x=11 } }
Output
11
4. Boolean Logical operator
It used to perform the logical operation between two or more condition.
| Operator | Example | Explain |
|---|---|---|
| && | (condition1) && (condition2) | AND(&&) operator will become true , when all the conditions are true. |
| || | (condition1) || (condition2) | OR(||) operator will become true , when any one condition is true. |
| ! | ! (condition) | NOT(!) operator perform the opposite of the condition. |
AND( && ) operator
Example
public class Main
{
public static void main(String[] args)
{
int x=5,y=6;
if((x<10)&&(x<y))
{
System.out.println("Both are true");
}
}
}
Output
Both condition are true
OR( || ) operator
Example
public class Main
{
public static void main(String[] args)
{
int x=5,y=6;
if((x==10)||(x<y))
{
System.out.println("condition true");
}
}
}
Output
condition true
NOT( ! ) operator
Example
public class Main
{
public static void main(String[] args)
{
int x=5;
if(!(x==10))
{
System.out.println("condition true");
}
}
}
Output
condition true
5. Bitwise operator
Bitwise operator used to perform the Logical operation and shift operation in a binary code.
| Operator | Example | Explain |
|---|---|---|
| & | x&y | To perform the AND operation of x,y binary code. |
| | | x|y | To perform the OR operation of x,y binary code. |
| ^ | x^y | To perform the XOR operation of x,y binary code. |
| << | x<<y | Left shift operator to perform the add the y number of 0's in x binary code in last. |
| >> | x>>y | Right shift operator to perform the remove the y number of binary code in last of x binary code. |
| >>> | x>>>y | Right shift filled with zero operator to perform the remove the last y number digit in x binary number. |
AND(&) operator:
Example
public class Main { public static void main(String[] args) { int x=5; // x=0 1 0 1 int y=6; // y=0 1 1 0 int z=x&y; // z=0 1 0 0 System.out.print(z); } }
Output
4
OR(|) operator:
Example
public class Main { public static void main(String[] args) { int x=5; // x=0 1 0 1 int y=6; // y=0 1 1 0 int z=x|y; // z=0 1 1 1 System.out.print(z); } }
Output
7
XOR(^) operator:
Example
public class Main { public static void main(String[] args) { int x=5; // x=0 1 0 1 int y=6; // y=0 1 1 0 int z=x^y; // z=0 0 1 1 System.out.print(z); } }
Output
3
Leftshift(<<) operator:
Example
public class Main { public static void main(String[] args) { int x=5; // x=0 1 0 1 int y=x<<2; // y=0 1 0 1 0 0 System.out.print(y); } }
Output
20
Rightshift(>>) operator:
Example
public class Main { public static void main(String[] args) { int x=5; // x=0 1 0 1 int y=x>>2; // y=0 1 System.out.print(y); } }
Output
1
Right shift filled with zero(>>>):
Example
public class Main { public static void main(String[] args) { int x=8; // x=1 0 0 0 int y=x>>>2; // y=1 0 System.out.print(y); } }
Output
2
6. Unary operator
Unary operator used to increment or decrement the value.It's mostly using , looping and recursion function. It's increment/decrement the value only one by one.
| Operator | Example | Explain |
|---|---|---|
| prefix Increment | ++x | It's increment the value. |
| prefix Decrement | --x | It's decrement the value. |
| postfix Increment | x++ | It's assign the value.But Not increment |
| postfix Decrement | x-- | It's assign the value.But not decrement |
Example-1
public class Main
{
public static void main(String[] args)
{
int x=5;
System.out.println(x++);
System.out.println(x);
}
}
Output
5 6
Example-2
public class Main
{
public static void main(String[] args)
{
int x=5;
System.out.println(++x);
System.out.println(x);
}
}
Output
6 6
Example-3
public class Main
{
public static void main(String[] args)
{
int x=5;
System.out.println(x--);
System.out.println(x);
}
}
Output
5 4
Example-4
public class Main
{
public static void main(String[] args)
{
int x=5;
System.out.println(--x);
System.out.println(x);
}
}
Output
4 4
7. Ternary operator
Ternary operator to perform like if else statement. "operand 1" is a condition.if condition is true ,"operand 2" will be execute , otherwise "operand 3" will be execute.
Syntax:
operand1 ? operand2 : operand3
Example
public class Main
{
public static void main(String[] args)
{
int m=5,n=6;
System.out.print(m<n?"n is greater":"m is greater");
}
}
Output
n is greater
