Boolean represents just two values, i.e. True or False.
A bool Data Type can accept only true or false.
public class MyApplication
{
public static void main(String[] args)
{
boolean x = true;
boolean y = false;
System.out.println(x);
System.out.println(y);
}
}
So, in the above code, we have created a variable named x of Boolean data type and initialised it with value True.
boolean x = true;

And created one more variable called y of Boolean data type and initialised it with value False.
boolean y = false;

But if we want to initialise a Boolean type variable with anything other than true/false, it would end up with an error.
