To create a Boolean variable, just as with other type variables, we declare it:

boolean isThisASushiCard;

Here, the type of the variable comes first, then the name of the variable, which is isThisASushiCard. The name is followed by a semi-colon (;) to show that the statement stops here.

To make use of this variable we can assign a value to it using the equals symbol (=).

boolean isThisASushiCard;
isThisASushiCard = true;

It is possible to combine the declaration and assignment into a single statement, called a definition, like so:

boolean isThisASushiCard = true;

Add the following code to a new file called FirstBoolean.java

public class FirstBoolean{
  public static void main(String[] args){
    boolean isThisASushiCard = true;
    System.out.println("It is " + isThisASushiCard + " that this is a sushi card");
  }
}

Compile FirstBoolean.java and then run FirstBoolean to see the output.
