Description

Datatype for the Boolean values true and false. It is common to use boolean values with control statements to determine the flow of a program. The first time a variable is written, it must be declared with a statement expressing its datatype.

Examples

```
size(400,400);
boolean a = false; 
if (!a) { 
  rect(120, 80, 200, 200); 
} 
a = true; 
if (a) { 
  line(80, 40, 360, 320); 
  line(80, 320, 360, 40); 
} 
```
