Arithmetic and Unary Operators

Introduction: Hello, this page will teach you about another two types of Operators in Java, Arithmetic and Unary. Arithmetic Operators - What are they? Arithmetic Operators are symbols used to perform a mathematical sum. There are five types of these:
+ Add
- Subtract
/ Division
* Multiplication
% Modular/Remainder
All of these operators have clear uses for anyone with basic knowledge of Math. Unary Operators - What are they? Unary Operators are used to manipulate a number value - at least, that's what I say. Again, there are five types of Unary Operators:
+ Indicates Positive Value
- Negates An Expression
++ Increments Value by 1
-- Decrements Value by 1
! Inverts Boolean Value
Examples: Here is an example of how Arithmetic Operators are used:
  1. int tutorial = 2;
  2. System.out.println(tutorial);
  3. tutorial = tutorial + 1;
  4. System.out.println(tutorial);
  5. tutorial = tutorial - 2;
  6. System.out.println(tutorial);
  7. tutorial = tutorial * 50;
  8. System.out.println(tutorial);
  9. tutorial = tutorial / 3;
  10. System.out.println(tutorial);
  11. tutorial = tutorial % 10;
  12. System.out.println(tutorial);
which gives the output:
2
3
1
50
16
6
And here is an example of how to use Unary Operators:
  1. int tut = 2;
  2. System.out.println(tut);
  3. tut++;
  4. System.out.println(tut);
  5. tut--;
  6. boolean opposite = false;
  7. if (!opposite){
  8. System.out.println(tut);
  9. }
Which gives the output:
2
3
2
Finished!
