Java operators

In Java, an operator is a symbol that performs an operation on one or more operands. Some of the common Java operators are:

1. Arithmetic Operators: +, -, *, /, %

2. Comparison Operators: ==, !=, >, <, >=, <=

3. Logical Operators: &&, ||, !

4. Assignment Operators: =, +=, -=, *=, /=, %=

5. Ternary Operator: ? :

6. Bitwise Operators: &, |, ^, ~, <<, >>, >>>

7. Conditional Operators: instanceof

Each operator has a specific function and precedence in expressions.

Java examples on operators

1. Arithmetic Operators:

int a = 10;

int b = 20;

int c = a + b; // c is 30

int d = b - a; // d is 10

int e = a * b; // e is 200

int f = b / a; // f is 2

int g = b % a; // g is 0

2.Comparison Operators:

int a = 10;

int b = 20;

if (a == b) {

   System.out.println("a is equal to b");

} else {

   System.out.println("a is not equal to b");

}

if (a > b) {

   System.out.println("a is greater than b");

} else {

   System.out.println("a is not greater than b");

}

3.Logical Operators:

 

boolean a = true;

boolean b = false;

if (a && b) {

   System.out.println("Both a and b are true");

} else {

   System.out.println("Either a or b is false");

}

if (a || b) {

   System.out.println("Either a or b is true");

} else {

   System.out.println("Neither a nor b is true");

}

if (!a) {

   System.out.println("a is false");

} else {

   System.out.println("a is true");

}

4. Assignment Operators:

int a = 10;

int b = 20;

a += b; // a is now 30

b -= a; // b is now -10

a *= b; // a is now -300

b /= a; // b is now 0

5. Ternary Operator:

int a = 10;

int b = 20;

int min = (a < b) ? a : b;

6.Bitwise Operators:

int a = 10;

int b = 20;

int c = a & b; // c is 0

int d = a | b; // d is 30

int e = a ^ b; // e is 30

int f = ~a; // f is -11

int g = a << 2; // g is 40

int h = b >> 2; // h is 5

7. Conditional Operator:

String str = "Hello";

if (str instanceof String) {

   System.out.println("str is an instance of String");

} else {

   System.out.println("str is not an instance of String");

}
