Re: Help with my java applet - displaying output with text
When posting code, please use the highlight tag to preserve formatting. Also, code should be in the form of an SSCCE. For example, I'm not sure what's giving you trouble- does the algorithm work? Does the applet show up? Start over and post only the code that's giving you trouble, hard-coding the rest (if your problem is displaying a String on a gui, write code that displays a hard-coded String on a gui first).

Re: Help with my java applet - displaying output with text
Well, this is the section of code we really care about:
Notice how you're appending the String so it contains the counts, separated by commas.
You say you want that String to contain more information. Why don't you just append that information the same way you append the comma?
Also, System.out.println() is your best friend. Don't be afraid to use it to check the value of the String as you go through the loop!

Re: Help with my java applet - displaying output with text
I understand what you mean by this but I am not sure on how to lay it out so it appears how i need it too? .
Re: Help with my java applet - displaying output with text
There are a couple ways to format text. You can either use html or escape characters such as \n for a newline and \t for a tab.Originally Posted by AdamLuke18

Re: Help with my java applet - displaying output with text
I just realized that you're using AWT instead of Swing. I'm not sure how AWT deals with escape characters and html. Is there a reason you aren't using Swing?
Also, I was wrong about escape characters working in components, at least for JLabels. Use html instead. Here's an example:
import javax.swing.JFrame; import javax.swing.JLabel; public class Test{ public static void main(String[] args) { JFrame frame = new JFrame("Test"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JLabel label = new JLabel("<html>one<br/>two</html>"); frame.add(label); frame.setSize(100, 100); frame.setVisible(true); } }
Alternatively, you could split this up into separate JLabels, one for each line.
As for setting your JLabel's size, do you mean the font size (if so, use html or the setFont() method if you aren't using html) or the size of the colored box around your text (if so, use a layout)?

Re: Help with my java applet - displaying output with text
For the number at the start, you're appending the value of the array at index i. I'm not sure how your algorithm works, but you need to make sure you're filling the array correctly. For the number at the end, you shouldn't just use a hard-coded "1" in your String. Again, you're looking at the value of the array at index i. It's up to you how that value and that index map to your output.
As for the multiple lines, I've given you several suggestions. Either use html (not sure if it works in AWT) or split the lines up into multiple JLabels.

Re: Help with my java applet - displaying output with text
Why were all the posts deleted?
Here's some of it:
Yeah sorry about that this is my first post. The algorithm works fine i just need to display the output as
There are:
2 words of length 1
1 word of length 2
1 word of length 3
whereas mine just outputs the numbers 2,1,1
I am not sure how to change this. I think I have to use a variable from the array and display it but i am not too sure. The array code isThe result button is currently displaying the 2,1,1 output.String array[]=text.split(" "); int counter=0; for(int i=0;i<array.length;i++) if(counter<array[i].length()) counter=array[i].length(); int intArray[]=new int[counter]; for(int i=0;i<intArray.length;i++){ intArray[i]=0; } for(int i=0;i<array.length;i++){ intArray[array[i].length()-1]++; } String mystring=""; for(int i=0;i<intArray.length;i++){ if(intArray[i]>0) { mystring+=String.valueOf(intArray[i]); mystring+=", "; } } result.setText(mystring); // set label here to display text
Thanks
If you don't understand my answer, don't ignore it, ask a question.
Re: Help with my java applet - displaying output with text
I would guess because OP was getting flak for crossposting, or maybe he found the answer and wants to get rid of any evidence of getting homework help online?
