What is "textpane"?

[shivam0101]

JtextPane

Have you looked at the API doc for the JTextPane? It has a link to the tutorial. In the tutorial are code examples of how to use the JTextPane.

I did look and tried, i am not getting the colors on each line, are there any methods available to get the line number?

textEditor.setText("This is first line\nThis is second line\nThis is third line");

StyledDocument doc = textEditor.getStyledDocument();
Style styleRed = textEditor.addStyle("Red", null);
StyleConstants.setForeground(styleRed, Color.red);

Style styleGreen = textEditor.addStyle("Green", null);
StyleConstants.setForeground(styleGreen, Color.green);

lines = textEditor.getText().split("\n");


for(int i=0; i<lines.length; i++)
{
doc.setCharacterAttributes(0, 4, styleRed, true);
doc.setCharacterAttributes(4, 6, styleGreen, true);
}

Why do you have a loop?

The point of using the setCharaterAttributes is to set the attributes for different characters in the the Document. You are attempting to set the first 5 characters to RED and the the next 2 characters to GREEN. There is no need to do this 3 times.

If you are having problems then post your Short, Self Contained, Correct Example. Don't forget to use the "code tags" so the code you post retains its formatting.

Yeah,
i want the first 5 chars to be red the next 3 char to be green of every line in the jtextpane.

And you still haven't posted your SSCCE.

every line in the jtextpane.

Every line starts at a different offset in the text. You'll need a way to remember where the first character of each line is.
