JAVA: Operator Aritmatik dengan Contoh

Operators constitute the basic building block to any programming language. Java too provides many types of operators which can be used according to the need to perform various calculations and functions, be it logical, arithmetic, relational, etc. They are classified based on the functionality they provide. Here are a few types:

• Arithmetic Operators
• Unary Operators
• Assignment Operator
• Relational Operators
• Logical Operators
• Ternary Operator
• Bitwise Operators
• Shift Operators

This article explains all that one needs to know regarding Arithmetic Operators.

Arithmetic Operators

These operators involve the mathematical operators that can be used to perform various simple or advanced arithmetic operations on the primitive data types referred to as the operands. These operators consist of various unary and binary operators that can be applied on a single or two operands. Let’s look at the various operators that Java has to provide under the arithmetic operators.

Now let’s look at each one of the arithmetic operators in Java:

1. Addition(+):

This operator is a binary operator and is used to add two operands.

Syntax:

num1 + num2

Example:

num1 = 10, num2 = 20
sum = num1 + num2 = 30

// Java code to illustrate Addition operator
  
import java.io.*;
  
class Addition {
    public static void main(String[] args)
    {
        // initializing variables
        int num1 = 10, num2 = 20, sum = 0;
  
        // Displaying num1 and num2
        System.out.println("num1 = " + num1);
        System.out.println("num2 = " + num2);
  
        // adding num1 and num2
        sum = num1 + num2;
        System.out.println("The sum = " + sum);
    }
}

Output

num1 = 10
num2 = 20
The sum = 30

2. Subtraction(-):

This operator is a binary operator and is used to subtract two operands.

Syntax:

num1 - num2

Example:

num1 = 20, num2 = 10
sub = num1 - num2 = 10

// Java code to illustrate Subtraction operator
  
import java.io.*;
  
class Subtraction {
    public static void main(String[] args)
    {
        // initializing variables
        int num1 = 20, num2 = 10, sub = 0;
  
        // Displaying num1 and num2
        System.out.println("num1 = " + num1);
        System.out.println("num2 = " + num2);
  
        // subtracting num1 and num2
        sub = num1 - num2;
        System.out.println("Subtraction = " + sub);
    }
}

Output

num1 = 20
num2 = 10
Subtraction = 10

3. Multiplication(*):

This operator is a binary operator and is used to multiply two operands.

Syntax:

num1 * num2

Example:

num1 = 20, num2 = 10
mult = num1 * num2 = 200

// Java code to illustrate Multiplication operator
  
import java.io.*;
  
class Multiplication {
    public static void main(String[] args)
    {
        // initializing variables
        int num1 = 20, num2 = 10, mult = 0;
  
        // Displaying num1 and num2
        System.out.println("num1 = " + num1);
        System.out.println("num2 = " + num2);
  
        // Multiplying num1 and num2
        mult = num1 * num2;
        System.out.println("Multiplication = " + mult);
    }
}

Output

num1 = 20
num2 = 10
Multiplication = 200

4. Division(/):

This is a binary operator that is used to divide the first operand(dividend) by the second operand(divisor) and give the quotient as a result.

Syntax:

num1 / num2

Example:

num1 = 20, num2 = 10
div = num1 / num2 = 2

// Java code to illustrate Division operator
  
import java.io.*;
  
class Division {
    public static void main(String[] args)
    {
        // initializing variables
        int num1 = 20, num2 = 10, div = 0;
  
        // Displaying num1 and num2
        System.out.println("num1 = " + num1);
        System.out.println("num2 = " + num2);
  
        // Dividing num1 and num2
        div = num1 / num2;
        System.out.println("Division = " + div);
    }
}

Output

num1 = 20
num2 = 10
Division = 2

5. Modulus(%):

This is a binary operator that is used to return the remainder when the first operand(dividend) is divided by the second operand(divisor).

Syntax:

num1 % num2

Example:

num1 = 5, num2 = 2
mod = num1 % num2 = 1

// Java code to illustrate Modulus operator
  
import java.io.*;
  
class Modulus {
    public static void main(String[] args)
    {
        // initializing variables
        int num1 = 5, num2 = 2, mod = 0;
  
        // Displaying num1 and num2
        System.out.println("num1 = " + num1);
        System.out.println("num2 = " + num2);
  
        // Remaindering num1 and num2
        mod = num1 % num2;
        System.out.println("Remainder = " + mod);
    }
}

Output

num1 = 5
num2 = 2
Remainder = 1
