sort number in ascending

[shana07]

Phew, I have problem..How to sort number in my files..I have these in my input files...: I need to sort the line in array [1] from 12, 64, 8, 128 etc.
3 12
4 64
7 8
10 128
...

I just wanna sort and number out them :
1 8
2 12
3 64
....
And my work...(I have tried to use bubbleSort() that I copied from people's ..)

public int[] bubbleSort(int array[]) {
boolean swappedOnPrevRun = true;
while(swappedOnPrevRun)
{
 swappedOnPrevRun = false;
 for(int i = 0; i < array.length - 1; i++){
 if(array[i] > array[i + 1])
{
 swappedOnPrevRun = true;		 	 	
int temp = array[i];	
array[i] = array[i + 1];	
array[i + 1] = temp;		 	 			}
	 	 		}
	 	 	}
 return array;
	 	 }

     private static String[] readLines (String fileName, int m) throws IOException
     {

     	List<String> lines = new ArrayList<String>();

     	String lineFRST = "";
     	Boolean readable = true;

        BufferedReader in1 = new BufferedReader (new FileReader( m + "File.txt"));


     	while (readable)
		{
		  lineFRST = in1.readLine();
          	  if (lineFRST != null)
	  {
	 lines.add(lineFRST);
	     readable = true;
	  }
		   else
	    readable = false;
		}

  return lines.toArray(new String[lines.size()]);

     }

     public static void main(String[] args) throws IOException
    {

        PrintWriter printWriter = null;
        BufferedWriter bufferWriter = null;

   for (int m=1; m<=40; m++)  
	   {
	     String[] lines = readLines (m + "Out.txt", m);  //read all lines from your file

         printWriter = new PrintWriter(new BufferedWriter(new FileWriter(m +"SORTED.txt", true)));

         for(int i = 0; i < lines.length; i++)
         {
            String[] theline = lines[i].split(" ");

            /*String[] num = theline[0];
              String[] toSort = theline[1];*/
                
            // need to convert string to int first....               

            printWriter.println( (i+1) + " : " + lines[i]);
        }
    \\      bubbleSort ();  \\need to parse the int

        printWriter.close();
  }

     }

Have a look at the article "generic heap sort algorithm" in the Java Articles section.

Jos, assist me on array syntax..what's wrong with my syntax here..
I will study about the article..thank you very much

for(int i = 0; i < lines.length; i++)
         {
            String[] theline = lines[i].split(" ");

            String[] testcase = theline[i];
		    String[] eod = theline[i];

            printWriter.println( (i+1) + " : " + lines[i]);
        }

            printWriter.println( (i+1) + " : " + lines[i]);
        }

"lines" is an array of Strings and so is "theline" but "theline[ i ]" is just one
single String and you can't cast a single String to another String array where
you want to initialize variable "testcase".

The article is about sorting name, please assist me on sorting integer ...
What do you think about the buble sort method as above ?

I'm sorry.I think I almost get there..I use this

String[] lines = readLines (m + "Input.txt", m);  //read all lines from your file
 printWriter = new PrintWriter(new BufferedWriter(new FileWriter(m +"SORTED.txt", true)));
 Arrays.sort (lines);

  for( i = 0; i < lines.length; i++)
   {
        printWriter.println("lines["+(i+1) +"] = "+lines[i]);

   }

But it's not yet correct order...please see below example..assist me anyone.
lines[1] = 100
lines[2] = 100
lines[3] = 104
lines[4] = 108
lines[5] = 112
lines[6] = 112
lines[7] = 112
lines[8] = 112
lines[9] = 12
lines[10] = 12
lines[11] = 12

Nope, bubble sort is a silly thing and nope, that article isn't about sorting names;
it's about anything that happens to be Sortable. Please read that article again
and try to understand what object oriented programming is all about.
The examples just showed two arrays of Strings that need to be sorted. It could
as easily have sorted two arrays of Integers or whatever; as long as that 'whatever'
implements the Sortable interface.
