PLZ help with the following:
IN JAVA

Given the following code where classes AA, BB and Q12 are in the same package. what would be the output? (if error exists, indicate the exact error(s), correct them and provide the output. If no error exist, provide the exact output of the program.

class AA{
int x1;
protected int x2;
public AA() {
System.out.println("Executing default constructor of AA");
xl=0;
x2=0;
}
public AA(int il, int i2) {
System.out.println("Executing parameterized constructor of AA");
xl=il;
x2=i2;
}
}
class BB extends AA{
public BB() {
super(50,60);
System.out.println("Executing default constructor of BB");
}
public BB(int il) {
System.out.println("Executing single-parameterized constructor of BB");
xl=il;
}
public BB(int il, int i2) {
System.out.println("Executing parameterized constructor of BB");
xl=il;
x2=i2;
}
}
public class Q12 {
public static void main(String[] args) {
AA al = new AA();
BB b1 = new BB(), b2= new BB(45,80);
AA a2 = new BB(90);
}
}
