Java Operator:
In Java a symbol are used perform operations. Like: +, -, *, / and many other Java Operators.
There are many types of operators in Java which are given below:
1. Unary Operator,
2.Arithmetic Operator,
3. Shift Operator,
4. Relational Operator
5. Bitwise Operator,
6. Logical Operator,
7.Ternary Operator and
8.Assignment Operator.
Java Operator Precedence:
| Operator Type | Category | Precedence |
| Unary | Postfix – Prefix – | expr++ expr— ++expr –expr +expr -expr ~ ! |
| Arithmetic | Multiplicative additive | * / % + – |
| Relational | Comparison equality | < > <= >= instanceof == != |
| Bitwise | bitwise AND b itwise exclusive OR | & ^ |
| Logical | bitwise inclusive OR logical AND logical OR | | && || |
| Ternary | ternary | ? : |
| Assignment | assignment | = += -= *= /= %= &= ^= |= <<= >>= >>>= |
| Shift | shift | << >> >>> |
Java Unary Operator:
The Java unary operators require only one operand. Unary operators are used to perform various operations i.e. :
- incrementing/decrementing a value by one
- negating an expression
- inverting the value of a boolean
Unary Operator Example: ++ and –
class OperatorExample{
public static void main(String args[]){
int x=10;
System.out.println(x++);//10 (11)
System.out.println(++x);//12
System.out.println(x–);//12 (11)
System.out.println(–x);//10
}}
Unary Operator Example 2: ++ and —
class OperatorExample{
public static void main(String args[]){
int a=10;
int b=10;
System.out.println(a++ + ++a);//10+12=22
System.out.println(b++ + b++);//10+11=21
}}
Unary Operator Example: ~ and !
class OperatorExample{
public static void main(String args[]){
int a=10;
int b=-10;
boolean c=true;
boolean d=false;
System.out.println(~a);//-11 (minus of total positive value which starts from 0)
System.out.println(~b);//9 (positive of total minus, positive starts from 0)
System.out.println(!c);//false (opposite of boolean value)
System.out.println(!d);//true
}}
Arithmetic Operators:
Java arithmatic operators are used to perform addition, subtraction, multiplication, and division. They act as basic mathematical operations.
Example :
class OperatorExample{
public static void main(String args[]){
int a=10;
int b=5;
System.out.println(a+b);//15
System.out.println(a-b);//5
System.out.println(a*b);//50
System.out.println(a/b);//2
System.out.println(a%b);//0
}}
