Define a public class named Flip with a single public instance method called flop that takes no parameters and returns a boolean. It should also provide a single constructor that takes a boolean argument that sets the initial state of the Flip instance.

Flip. java

public class Flip {

/ / private attribute indicating state

private boolean state;

/ / constructor taking initial boolean value for the state

public Flip (boolean state) {

this. state = state;

}

/ / method to switch the state and return new state

public boolean flop () {

/ / changing state to false if it is true, true if it is false

state = ! state;

/ / returning the new state

return state;

}

/ / main method containing code for testing. remove if you don't need this

public static void main (String[] args) {

Flip flip = new Flip (true);

System. out. println (flip. flop ()); / / false

System. out. println (flip. flop ()); / / true

System. out. println (flip. flop ()); / / false

Flip flop = new Flip (false);

System. out. println (flop. flop ()); / / true

System. out. println (flop. flop ()); / / false

System. out. println (flop. flop ()); / / true

}

}
