Analyze the following code:

public class Test {
public static void main(String[] args) {
​boolean[][] x = new boolean[3][];
​x[0] = new boolean[1]; x[1] = new boolean[2];
​x[2] = new boolean[3];

​System.out.println("x[2][2] is " + x[2][2]);
}
}

◦ The program has a compile error because new boolean[3][] is wrong.
◦ The program runs and displays x[2][2] is null.
◦ The program has a runtime error because x[2][2] is null.
◦ The program runs and displays x[2][2] is true.
◦ The program runs and displays x[2][2] is false.
