java tutorial, java lessonThe following is the example we used in previous lesson.

1. class variable
2. {
3. public static void main(String[] args)
4. {
5. int HisBooks=30;
6. int MyBooks=40;
7. int TotalBooks=HisBooks+MyBooks;
8. System.out.println("Total books we have="+TotalBooks);
9. }
10. }

We used int variables in the above code. In Line 7 ,we used Arithmetic Operators +.

Arithmetic Operators

Arithmetic Operators is very similar to what you learn from school. Only a little bit difference. For example, you use ÷ for divide, I use / for divide.

(Since there is no such ÷ key in my keyboard. :>)

I use * for multiplication.

Operator Sign Example
Addition + 3+2
Subtraction - 5-3
Multiplication * 2*5
division / 18/3
remainder % 7%4=3
