random boolean in Constructor

[keo]

When I make a new object, I want the constructor to randomly make a field true OR false.
I've imported the util (import java.util.Random;)
I've attempted to do stuff like this:

//Variables
private boolean field;
private Random rnd

//Constructor
field = rnd nextBoolean();

Which returns a NullPointerException. Help please!

You did not create a new Random object to use (using new Random(....)). You are trying to use a blank (null) rand object.

Also, the easiest way to make a random boolean is this:

boolean b = (Math.random() < .5);

And there you have it, a 50-50 chance for true or false.
