Java OCA OCP Practice Question 1066

Question

What is the output of the following program? 

1:  public class Main { 
2:    public String name; 
3:    public void parseName() { 
4:      System.out.print("1"); 
5:      try { //from  ww w .  j a v a  2  s. c  o  m
6:        System.out.print("2"); 
7:        int x = Integer.parseInt(name); 
8:        System.out.print("3"); 
9:      } catch (NumberFormatException e) { 
10:       System.out.print("4"); 
11:     } 
12:   } 
13:   public static void main(String[] args) { 
14:     Main m = new Main(); 
15:     m.name = "Leroy"; 
16:     m.parseName(); 
17:     System.out.print("5"); 
18:   } 
19:}
  • A. 12
  • B. 1234
  • C. 1235
  • D. 124
  • E. 1245
  • F. The code does not compile.
  • G. An uncaught exception is thrown. 


E.

Note

The parseName() method is invoked within main() on a new Main object.

Line 4 prints 1.

The try block executes and 2 is printed.

Line 7 throws a NumberFormatException, so line 8 doesn't execute.

The exception is caught on line 9, and line 10 prints 4.

Because the exception is handled, execution resumes normally.

parseName runs to completion, and line 17 executes, printing 5.

That's the end of the program, so the output is 1245.
