Java has a built-in data type, boolean, to represent Boolean values. A variable of type boolean can be either true or false. Note that true and false are special literals in Java. The following BooleanDemo program demonstrates using the boolean datatype. Study the BooleanDemo program and try to determine what the output will be.
public class BooleanDemo
{
public static void main(String [] args)
{
boolean t = true;
System.out.println(“t is “ + t);
int x = 10;
boolean y = (x > 15);
System.out.println(“y is “ + y);
// y = x; // Does not compile!
}
}
