Program Plan Intro
Program:
//definition of class Test
public class Test
{
//declaration of main function
public static void main(String[] args)
{
/*declaration of the abstract class Number and assigning value as 3 */
Number x = 3;
/*Reference the intValue() function of integer type using object x and print the value */
System.out.println(x.intValue());
/*Reference the doubleValue() function of
double type using object x and print the value */
System.out.println(x.doubleValue());
}

Examine this code and determine what happens when it is run:
1 public class Test {
int x;
2
3
public Test(String t){
System.out.println("Test");
}
public static void main(String[] args) {
Test test = new Test ("boo");
System.out.println(test.x);
}

10 }
The program has a compile error because Test does not have a default
constructor.
The program has a compile error because System.out.println method cannot be
invoked from the constructor.
) The program runs successfully and prints out:
Test
O The program has a compile error because you cannot create an object from the
class that defines the object.
