What will be the output of the program?
class Base {
Base() {
System.out.print("Base");
}
}
public class Alpha extends Base {
public static void main(String[] args) {
new Alpha(); / * Line 12 * /
new Base(); / *Line 13 * /
}
}
Base
BaseBase
Compilation fails
The code runs with no output
Explanation:
Option B is correct. It would be correct if the code had compiled, and the subclass Alpha had been saved in its own file. In this case Java supplies an implicit call from the sub-class constructor to the no-args constructor of the super-class therefore line 12 causes Base to be output. Line 13 also causes Base to be output.
