Types of Operator in Java?
- It is a special symbol which is used to perform logical or mathematical operation on data or variable.
Operand
- It is a data or variable on which the operation is to be performed.
Types of Operator
- ⇒Arithmetic Operators
- ⇒Relational Operators
- ⇒Logical Operators
- ⇒Assignment Operators
- ⇒Bitwise Operators
- ⇒Increment/Decrement Operators
- ⇒Conditional Operators
Arithmetic Operators
| Symbol | Operation | Example |
| + | Addition | x+y |
| - | Subtraction | x-y |
| * | Multiplication | x*y |
| / | Division | x/y |
| % | Modulus | x%y |
class Easy
{
public static void main(String[] args)
{
int a=5,b=3;
System.out.println("Add="+(a+b));
System.out.println("Sub="+(a-b));
System.out.println("Multi="+(a*b));
System.out.println("Div="+(a/b));
//Note:-modulus(%) always holds remainder value
System.out.println("Mod="+(a%b));
}
}
/*
### Output ###
Add=8
Sub=2
Multi=15
Div=1
Mod=2
*/
Relational Operators
| Symbol | Operation | Example |
| == | Equal to | 2==3 returns 0 |
| != | Not equal to | 2!=3 returns 1 |
| > | Greater than | 2>3 returns 0 |
| < | Less than | 2<3 returns 1 |
| >= | Greater than or equal to | 2>=3 returns 0 |
| <= | Less than or equal to | 2<=3 returns 1 |
Logical Operators
| (x>y)&&(x>z) | Here this expression returns true if both conditions are true. |
| (x>y)||(x>z) | Here this expression returns true if any one or both conditions are true. |
| !(x>y) | Not operator reverses the state means if the condition is true it returns false and if the condition is false it returns true. |
class Easy
{
public static void main(String[] args)
{
int a=10,b=60,c=40;
if(a>b&&a>c)
System.out.println("a is greatest");
if(b>a&&b>c)
System.out.println("b is greatest");
if(c>a&&c>b)
System.out.println("c is greatest");
}
}
/*
### Output ###
b is greatest
*/
Assignment Operators
| Symbol | Example | Same as |
| = | x=y | x=y |
| += | x+=y | x=x+y |
| -= | x-=y | x=x-y |
| *= | x*=y | x=x*y |
| /= | x/=y | x=x/y |
| %= | x%=y | x=x%y |
class Easy
{
public static void main(String[] args)
{
int x1=5,y1=3;
x1+=y1;//x1=x1+y1
System.out.println(x1);
int x2=5,y2=3;
x2-=y2;//x2=x2-y2
System.out.println(x2);
int x3=5,y3=3;
x3*=y3;//x3=x3*y3
System.out.println(x3);
int x4=5,y4=3;
x4/=y4;//x4=x4/y4
System.out.println(x4);
int x5=5,y5=3;
x5%=y5;//x5=x5%y5
System.out.println(x5);
}
}
/*
### Output ###
8
2
15
1
2
*/
Bitwise Operators
| Symbol | Operation | Example |
| & | Bitwise AND | x&y |
| | | Bitwise OR | x|y |
| << | Shift Left | x<<2 |
| >> | Shift Right | x>>2 |
| ^ | X-OR | x^y |
class Easy
{
public static void main(String[] args)
{//variable declaration
int a=5,b=3,c;
c=a&b;//AND Operation
System.out.println("a&b="+c);
c=a|b;//OR Operation
System.out.println("a|b="+c);
c=a>>2;//Shift right Operation
System.out.println("a>>2="+c);
c=a<<2;//Shift left Operation
System.out.println("a<<2="+c);
c=a^2;//X-OR Operation
System.out.println("a^2="+c);
}
}
/*
### Output ###
a&b=1
a|b=7
a>>2=1
a<<2=20
a^2=7
*/
Increment/Decrement Operators
| Symbol | Name | Function | Example |
| ++ | Increment | It increments the value by 1 | ++x |
| -- | Decrement | It decrements the value by 1 | --x |
class Easy
{
public static void main(String[] args)
{//variable declaration
int a=5,b=10;
System.out.println(++a);
System.out.println(--b);
}
}
/*
### Output ###
6
9
*/
Conditional Operators
- If the condition is true second part will execute otherwise third part will execute.
class Easy
{
public static void main(String[] args)
{//variable declaration
int a=5,b=10,max;
max=a>b?a:b;
//don't be confused,here + is separator in java
System.out.println("Greater value is "+max);
}
}
/*
### Output ###
Greater value is 10
*/
