Question

The following code may contain some errors. Identify the errors, modify the program by underlining the changes made, and write the aim of the program.

import java.io.*;
class clPaperB
{
    int TY[];
    clPaperB(int n)
    {
       TY = new int [n];
    {
    void fnInputB()
    {
      Scanner sc = new Scanner(System.in);
      int s = TY.length;
      for(int j = 0; j <= s − 1; j++)
      {
          System.out.print("Enter value for cell num " + j +" : ");
          TY[j] = sc.nextInt();
      }
    }
    void fnWorkB()
    {
      for(int p = 0; p<=s; p++)
      {
       for(int q = 0; q<=sp; p++)
       {
           if(TY[q+1]> TY[q])
           {
              tmp = TY[p];
              TY[p] = TY[p +1];
              TY[p + 1] = tmp;
            }
        }
      }
    }
    void fnShow()
    {
       System.out.println(" The elements in Descending Order ...")
       for(int j = 0; j<=s - 1; j++)
       System.out.print(" TY[j] ");
    }
}

Answer 1

Syntax errors: Variable s is local to method fnInputB(). It should be made of member data. Variable 'tmp' has not been declared.

Logical Error: in bubble sort, elements are printed inside quotes as string.

importjava.util.*;
class clPaperB
{
     int TY[]; int s;
    clPaperB(int n)
    {
        TY = new int [n];
    }
    void fnInputB()
    {
        Scanner sc = new Scanner(System.in);
        s = TY.length;
        for(int j = 0; j <= s - 1; j++)
        {
             System.out.print("Enter value for cell num" + j +" : ");
             TY[j] = sc.nextInt();
        }
    }
    void fnWorkB()
    {
        for(int p =0; p<s; p++)
        {
             for(int q = 0; q<=s-p-2; q++)
             {
                 if(TY[q + 1]> TY[q])
                 {
                     int tmp = TY[q];
                     TY[q] = TY[q+1];
                    TY[q+1] = tmp;
                 }
             }
        }
    }
    void fnShow()
    {
             System.out.println(" The elements in descending-Order ...");
             for (int j = 0; j <= s - 1; j++)
             System.out.print(TY[j] + " "
    }
}

Output:

Enter elements: 55 22 88 66 44

The elements in descending order...

88 66 55 44 22

Aim: The aim of this programme is to arrange the data in ascending order.
