Using boolean Data Type
Practise your skills and try to change the code. Read the comments and try what is within the TODO comment.
class BooleanDemo {
public static void main (String[] args) {
//boolean type hold the value of either true or false
boolean loggedIn = true;
System.out.println("loggedIn " + loggedIn);
//when using boolean types, the convention is to use is before the variable name
boolean isAuthenticated = false;
System.out.println("isAuthenticated " + isAuthenticated);
//boolean types are used in conditional statements
//The double equals(==) checks for equality. We will cover the if statement later on
if(isAuthenticated == true){
System.out.println("I am auntenticated");
}else {
System.out.println("I am not auntenticated");
}
//TODO
//Change the isAuthenticated to false
//And change the order of the expression in the if statement so that it outputs the right message
}
}
