Display in a text area

**susieferrari** · March 14th, 2011, 04:38 AM

Hi all, I am new in this forum and this is my first post: I am a Java beginner and I hope to have some help from you.

I my main class (SplitJFrame) I have a GUI with a text area: in another class (FileImport) I have a method to read a txt file, put it in an array and print the array.

public void importToArray(){
        int rows = 0;
        bin = new String[numberOfLines()][6];
        try {
             FileReader fr = new FileReader(fileToImport);
             BufferedReader br = new BufferedReader(fr);
             String line = null;
 
        while((line = br.readLine())!= null){
                 StringTokenizer stk = new StringTokenizer(line, ",");
                 while(stk.hasMoreTokens()){
                     for (int cls = 0;cls<6; cls++){
                         bin[rows][cls]= stk.nextToken();
                     }
                     rows++;
                 }//end inner while loop
             }//end outer while loop
             br.close();
        }//end try
        catch(Exception e){
            System.out.println(e);
        }
    }

public void printArray(){
        for(int i =0;i<bin.length; i++){
            System.out.printf("%s ", i);
            for(int j =0;j<bin[i].length; j++){
                System.out.printf("%s ", bin[i][j]);
            }
            System.out.println("");
        }//end for loop
    }

Plus another simple method that return the array

public String[][] getArray(){
        return bin;
    }

I would like to display in text area first 3 and last 3 rows of txt file stored in array named bin.

How can I do this?

Thanks!

Susanna

Hey Susanna, welcome to the forums

Can you please show me an example .txt file for the import?
It may also be worth posting all of your code so I can compile it. Thanks

Hi JavaPF, thanks for your kind reply!

This is an example of text file

PS txt file length may have different rows number

**JavaPF** · March 14th, 2011, 08:58 AM

Thanks for the updated information.

So currently, what doesn't work about the code? Is it just storing the information in an array and then printing it?

Yes correct. Now these methods let me store txt file in an array I called bin and print it.

I would like to have first 3 and last 3 rows of this array displayed in a text area in main class, with a System.out.print ("----------") in between.

Thanks!

I'm unable to compile the code correctly.

I'm having issues with initComponents(); and Date newDate = sdf.parse(d[i][0]);

Even with these commented out, It still won't compile correctly.

Maybe it is because I didn't copy greyed generated code area.

The updated SplitJFrame class has stoped the initComponents(); issue. Thanks for that.

I'm now looking into the problem with Date newDate = sdf.parse(d[i][0]);
The current problem is - Type mismatch: cannot convert from java.util.Date to Date

**JavaPF** · March 15th, 2011, 08:29 AM

OK well I've commented out:

                       Date newDate = sdf.parse(d[i][0]);//parse first column to Date
                       dateArray[i] = newDate;

The GUI runs fine and I have imported an example file.
When the file is imported, it displays this in the console:

true

Do you wish to display the first 3 and last 3 rows of this output in jDataPreviewTextArea?

**susieferrari** · March 15th, 2011, 10:41 AM

Well I'm glad it all runs fine.

What I would like to display is something like this

0 20100401 6189.38 6238.57 6186.59 6235.56 29546500
1 20100405 6235.56 6235.56 6235.56 6235.56 0

7 20100413 6236.28 6251.46 6199.71 6230.83 28970000

So to see first and last rows of txt file; rows displayed are only from bin array

Susanna

**JavaPF** · March 16th, 2011, 11:59 AM

In your SplitJFrame class, find the jFileReaderActionPerformed(java.awt.event.ActionEv ent evt) method, and add this under obj1.printArray();

      //TEST CODE      
 
      for(int i =0;i<3; i++){  
    	  jDataPreviewTextArea.setText(jDataPreviewTextArea.getText().trim() + i + ")");
    	  for(int j =0;j<obj1.bin[i].length; j++){
    		  jDataPreviewTextArea.setText(jDataPreviewTextArea.getText() + " " + String.valueOf(obj1.bin[i][j]));
    	  }
    	  		jDataPreviewTextArea.setText(jDataPreviewTextArea.getText() + "\n");    	  
      }      
      //END TEST CODE

In theory this should work.

I will continue this as soon as possible

**susieferrari** · March 16th, 2011, 03:11 PM

Thank you very much!

It works fine, it plots first 3 rows in a text area; would it be an alternative solution to create a new array in which to copy first 3 and last three rows from array bin?

Susanna

**JavaPF** · March 16th, 2011, 04:03 PM

Good I'm glad that worked. Tomorrow I will help you display the last 3 rows.
Yes you could possibly create a new array for those values but I don't see the point unless you need to call them again.

**JavaPF** · March 17th, 2011, 11:32 AM

I must be going mad

I'm not sure why this is not adding the new lines in correctly.

The code I am working on is:

it's not appending the newline because every time through the loop you're re-trimming the text. The net result is only the very last newline is left when you exit the loop. Also, for better performance use a StringBuilder.

Try this:

StringBuilder temp = new StringBuilder(jDataPreviewTextArea.getText());
			final int NUM_LINES = 3;
			for(int i =0;i<NUM_LINES; i++){
				temp.append(i);
				temp.append(")");    	  		
				for(int j =0;j<obj1.bin[i].length; j++){
					temp.append(" ");
					temp.append(String.valueOf(obj1.bin[i][j]));
				}
				if (i < NUM_LINES - 1)
				{
					temp.append("\n");
				}
			}
			jDataPreviewTextArea.setText(temp.toString());

Thank you very much to you all!

Now it print perfectly first 3 rows in txt area, is there a method to set font size?

Thanks, I forgot I can set font size and color directly from palette - properties in NetBeans

This is how it looks now

OK here is the updated code. I have implemented helloworld922's solution.

This will show the first 3 and last 3 lines of the input file.

Place this code just after obj1.printArray(); in the SplitJFrame class:

  	//JPF TEST CODE - FIRST 3 & LAST 3 LINES //      
      	String line = "--------------------------------------";
 
      	StringBuilder firstThree = new StringBuilder(jDataPreviewTextArea.getText());
		final int NUM_LINES = 3;
 
		for(int i = 0;i<NUM_LINES; i++){
			firstThree.append(i);
			firstThree.append(")");    	  		
			for(int j = 0;j<obj1.bin[i].length; j++){
				firstThree.append(" ");
				firstThree.append(String.valueOf(obj1.bin[i][j]));
			}
			if (i < NUM_LINES - 1)
			{
				firstThree.append("\n");
			}			
		}		
		jDataPreviewTextArea.setText(firstThree.toString());
		jDataPreviewTextArea.setText(jDataPreviewTextArea.getText() + "\n" + line + "\n");
 
		final int totalNumberOfLines = obj1.numberOfLines();
		final int minusThree = (totalNumberOfLines - 3);		
 
		StringBuilder lastThree = new StringBuilder(jDataPreviewTextArea.getText());
		for(int k = minusThree; k < totalNumberOfLines; k++){
			lastThree.append(k);
			lastThree.append(")");
			for(int j = 0;j<obj1.bin[k].length; j++){
				lastThree.append(" ");
				lastThree.append(String.valueOf(obj1.bin[k][j]));
			}
			if (k < totalNumberOfLines - 1)
			{
				lastThree.append("\n");
			}
		}
		jDataPreviewTextArea.setText(lastThree.toString());
		//END JPF TEST CODE - FIRST 3 & LAST 3 LINES //

When the details are displayed in the TextArea, the scroll bars move with it and scroll to the end of the data.

For easy readability and to stop this from happening, I suggest you add:

jDataPreviewTextArea.setCaretPosition(0);

Just under:

jDataPreviewTextArea.setText(lastThree.toString());

The updated code now looks like this:

      	//JPF TEST CODE - FIRST 3 & LAST 3 LINES //      
      	String line = "--------------------------------------";
 
      	StringBuilder firstThree = new StringBuilder(jDataPreviewTextArea.getText());
		final int NUM_LINES = 3;
 
		for(int i = 0;i<NUM_LINES; i++){
			firstThree.append(i);
			firstThree.append(")");    	  		
			for(int j = 0;j<obj1.bin[i].length; j++){
				firstThree.append(" ");
				firstThree.append(String.valueOf(obj1.bin[i][j]));
			}
			if (i < NUM_LINES - 1)
			{
				firstThree.append("\n");
			}			
		}		
		jDataPreviewTextArea.setText(firstThree.toString());
		jDataPreviewTextArea.setText(jDataPreviewTextArea.getText() + "\n" + line + "\n");
 
		final int totalNumberOfLines = obj1.numberOfLines();
		final int minusThree = (totalNumberOfLines - 3);		
 
		StringBuilder lastThree = new StringBuilder(jDataPreviewTextArea.getText());
		for(int k = minusThree; k < totalNumberOfLines; k++){
			lastThree.append(k);
			lastThree.append(")");
			for(int j = 0;j<obj1.bin[k].length; j++){
				lastThree.append(" ");
				lastThree.append(String.valueOf(obj1.bin[k][j]));
			}
			if (k < totalNumberOfLines - 1)
			{
				lastThree.append("\n");
			}
		}
		jDataPreviewTextArea.setText(lastThree.toString());		
		jDataPreviewTextArea.setCaretPosition(0);
		//END JPF TEST CODE - FIRST 3 & LAST 3 LINES //
