Question

Identify errors and correct them of the following Java program:

1. import java.utility.Random; 2. 3. public class Sequen 4. 5. private int stand 6. private int calc; 7. 8. public Sequen(int numStand) 9. { 10. stand = numStand; 11. skip; 12. } 13. 14. public void skip() 15. { 16. Random sit = new Random(); 17. calc = sit.nextInt(stand) + 1; 18. } 19. 20. public getStand() 21. { 22. return stand; 23. } 24. 25. int getCalc() 26. { 27. return calc; 28. } 29. } One error is already identified for you as shown below: Line Number: 5 Error description: Missing semicolon Statement after correction: private int stand; Identify 5 other errors and give their Line Number, Error description and Statement after correction.

Answer 1

After corecting the errors the java code will look as follows:

import java.util.Random;
//since utility is not a package it is replaced by util
class Sequence //change class name (optional)
{
    private int stand; //at end of statement ';' is necessary
    private int calc; //at end of statement ';' is necessary
    public Sequence(int numStand)
    {
        stand = numStand;
        skip(); //method needs to have '()'at the end skip; changed to skip(); 
        
    }
    public void skip()
    {
        Random sit = new Random();
        calc = sit.nextInt(stand) + 1;
    }
    public int getStand() //should have datatype declared 'int'
    {
        return stand;
    }
    int getCalc()
    {
        return calc;
    } 
} 
// all errors are corrected.

The errors are marked by giving the code lines before correcting are written in comments in the code file.
