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:
int tutorial = 2;
tutorial = tutorial + 1;
tutorial = tutorial - 2;
tutorial = tutorial * 50;
tutorial = tutorial / 3;
tutorial = tutorial % 10;
which gives the output:
2
3
1
50
16
6
And here is an example of how to use Unary Operators:
int tut = 2;
tut++;
tut--;
boolean opposite = false;
if (!opposite){
}
Which gives the output:
2
3
2
