Arithmetic assignment operations

Combine arithmetic and assignment into a single operation to save coding time
All five basic arithmetic operations have a corresponding arithmetic assignment operator .

Operator	Operation
+=	Addition assignment
-=	Subtraction assignment
*=	Multiplication assignment
/=	Division assignment
%=	Modulo (remainder) assignment

Example:

This program reads a percentage value from the user (such as 5.5) and converts to the correct decimal equivalent (such as 0.055) by using the division assignment operator.

import java.util.*;
import java.io.*;

public class AppStr
{
public static void main(String[] args)
{

// Variable for holding a percentage entered by the user // Prompt for and read the percentage System.out.print(“Enter a percentage in n.nn format: “);
double percent;
Scanner Keyboard = new Scanner(System.in);

percent = Keyboard.nextDouble();
//percent = Keyboard.readDouble();
// Convert it to its decimal equivalent and display the result
percent /= 100;
System.out.println(“The decimal equivalent is ” + percent);
}
}
