Java Operators
Java Tutorial » Java Operators
Operators as : sum, multiplied, decrease , etc... are used to perform operations on variables and values.
In the below example, we use sum, multiplied, decrease and division operator to see how it is working:
Example:
150
500
5
2
public class Main {
public static void main(String[] args) {
int x = 100 + 50; // sum
int y = 10 * 50; // multiplied
int z = 10 - 5; // decrease
int w = 10 / 5; // division
System.out.println(x);
System.out.println(y);
System.out.println(z);
System.out.println(w);
}
}
Output:public static void main(String[] args) {
int x = 100 + 50; // sum
int y = 10 * 50; // multiplied
int z = 10 - 5; // decrease
int w = 10 / 5; // division
System.out.println(x);
System.out.println(y);
System.out.println(z);
System.out.println(w);
}
}

Arithmetic Operators
For variable X holds 15 and variable Y holds 25,
+ (Addition) Adds values. X + Y will give 40
- (Subtraction) Subtracts one value from another. X - Y will give -10
* (Multiplication) Multiplies values. X * Y will give 375
/ (Division) Divides one value by another. Y / X will give 1
% (Modulus) Returns the division remainder. Y % X will give 10
++ (Increment) Increases the value of operand by 1. X++ gives 16
-- (Decrement) Decreases the value of operand by 1. X-- gives 14
Example: assign value
System.out.println(z);
System.out.println(w);
System.out.println(t);
System.out.println(s); }
}
Output:
24
43
23
400

public class Main {
public static void main(String[] args) {
int y = 24;
//adds a value to a variable
int z = 33;
z +=10 ;
//Subtract a value to a variable
int w = 33;
w -=10 ;
//Multiplay
int t = 40;
t *=10 ;
//Divide
int s = 33;
s /=11 ;
//
System.out.println(z);
System.out.println(w);
System.out.println(t);
System.out.println(s); }
}

Java Comparison Operators
Comparison operators java are used to compare two values:
Example:
false
true
true
false
true
false
public class Main {
public static void main(String[] args) {
int z = 14;
int w = 7;
System.out.println(z == w); // Equal to - false because 14 is not equal to 7
System.out.println(z != w); // Not equal - true because 14 is not equal to 7
System.out.println(z > w); // Greater than - true because 14 is greater than 7
System.out.println(z < w); // Less than - false because 14 is not less than 7
System.out.println(z >= w); // Greater than or equal to - true because 14 is greater, or equal,to 7
System.out.println(z <= w); // Less than or equal to - false because 14 is neither less than or equal to 7
}
}
Output:public static void main(String[] args) {
int z = 14;
int w = 7;
System.out.println(z == w); // Equal to - false because 14 is not equal to 7
System.out.println(z != w); // Not equal - true because 14 is not equal to 7
System.out.println(z > w); // Greater than - true because 14 is greater than 7
System.out.println(z < w); // Less than - false because 14 is not less than 7
System.out.println(z >= w); // Greater than or equal to - true because 14 is greater, or equal,to 7
System.out.println(z <= w); // Less than or equal to - false because 14 is neither less than or equal to 7
}
}
