Operators in Java
Operators in Java
Operator is a special symbol that tells the compiler to perform specific mathematical or logical Operation. Java supports following lists of operators.
- Arithmetic Operators
- Relational Operators
- Logical Operators
- Bitwise Operators
- Assignment Operators
- Ternary or Conditional Operators
Arithmetic Operators
Given table shows all the Arithmetic operator supported by Java Language. Lets suppose variable A hold 8 and B hold 3.
Java arithmetic operator takes numerical values as operands, operates on them, and returns a single numerical value. Java Arithmetic operators are used for simple mathematic operations, they are
- Addition (+)
- Subtraction (-)
- Multiplication (*)
- Division (/)
- Modulus (%)
| Operator | Example (int A=8, B=3) | Result |
|---|---|---|
| + | A+B | 11 |
| - | A-B | 5 |
| * | A*B | 24 |
| / | A/B | 2 |
| % | A%4 | 0 |
Relational Operators
Which can be used to check the Condition, it always return true or false. Lets suppose variable A hold 8 and B hold 3.
| Operators | Example (int A=8, B=3) | Result |
|---|---|---|
| < | A<B | False |
| <= | A<=10 | True |
| > | A>B | True |
| >= | A<=B | False |
| == | A== B | False |
| != | A!=(-4) | True |
Logical Operator
Which can be used to combine more than one Condition?. Suppose you want to combined two conditions A<B and B>C, then you need to use Logical Operator like (A<B) && (B>C). Here && is Logical Operator.
| Operator | Example (int A=8, B=3, C=-10) | Result |
|---|---|---|
| && | (A<B) && (B>C) | False |
| || | (B!=-C) || (A==B) | True |
| ! | !(B<=-A) | True |

|---|---|---|---|---|---|
| T | T | T | T | F | F |
| T | F | F | T | F | T |
| F | T | F | T | T | F |
| F | F | F | F | T | T |
Assignment operators
Which can be used to assign a value to a variable. Lets suppose variable A hold 8 and B hold 3.
| Operator | Example (int A=8, B=3) | Result |
|---|---|---|
| += | A+=B or A=A+B | 11 |
| -= | A-=3 or A=A+3 | 5 |
| *= | A*=7 or A=A*7 | 56 |
| /= | A/=B or A=A/B | 2 |
| %= | A%=5 or A=A%5 | 3 |
| =a=b | Value of b will be assigned to a |
Ternary operator
If any operator is used on three operands or variable is known as ternary operator. It can be represented with " ?: "
