If I understand you correctly, look into the FontMetrics class. http://java.sun.com/j2se/1.5.0/docs/api/java/awt/FontMetrics.html

In my experience, and this may have changed since I tried it last, spaces are not computed accurately by font metrics. I had to substitute the width of another letter for a space to make what I wanted to do work.

captain i think this is what i want (FontMetrics)but why cannot i do this.FontMetrics metrics = new FontMetrics(); secondly tave how did you figure out the height and width of a text then?

i am using swing a textField in which a user will enter a text and then if he/she clicks the button it will give him/her the output that this word is bigger than the other word.

Because the only constructor is:

FontMetrics

protected FontMetrics(Font font)

Creates a new FontMetrics object for finding out height and width

information about the specified Font and specific character glyphs in that

Font.

Parameters:

font - the Font

class AddTextListener implements ActionListener

{

public void actionPerformed(ActionEvent event)

{

FontMetrics metrics = textField.getFontMetrics(font);

int fontHeight = metrics.getHeight();

String text = textField.getText();

int textWidth = metrics.stringWidth(text);

resultLabel.setText(textWidth);//error is here

}

i know it will take string but how can i convert it into int? i tried Integer.ParseInt(resultLabel.getText()) but still not working because resultLabel is a string.

Just add a ""+ ... resultLabel.setText(""+textWidth)
