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:

int tutorial = 2;
System.out.println(tutorial);
tutorial = tutorial + 1;
System.out.println(tutorial);
tutorial = tutorial - 2;
System.out.println(tutorial);
tutorial = tutorial * 50;
System.out.println(tutorial);
tutorial = tutorial / 3;
System.out.println(tutorial);
tutorial = tutorial % 10;
System.out.println(tutorial);

which gives the output:

And here is an example of how to use Unary Operators:

int tut = 2;
System.out.println(tut);
tut++;
System.out.println(tut);
tut--;
boolean opposite = false;
if (!opposite){
	System.out.println(tut);
}

Which gives the output:

2
3
2

Finished!
