I am creating a text editor using JTextPane that allows the user to bold, color and align the text by highlighting the text then selecting the option to either bold, color or align. After the adjustment is made, the selection goes away, but I want it to stay. Is there a way to get it to stay, or should I manually reselect the text? If so, how can I do that?
The example in Oracle's Java Tutorials does what you need and provides the source code.

I am looking for a way to print content in JTextComponent's text with multiple fonts and styles.
For example: first Title with bigger font and then some custom text in different style in one component
You can use a JTextPane for this. You can control font, color, bold, size etc.
Read the section from the Swing tutorial on Text Component Features for more information and working examples.
For a another simple example to get you started check out: Is there a way to filter / search for content in a HTMLEditorKit?
I am developing a spam detector application using Java GUI (NetBeans). Now I have a simple user interface which includes a text area in which the user is going to paste his email in to order to check if its a spam or not, but the problem is when you paste a text in the text area all the text properties will be lost such as : Font type, color, hyperlinks etc...
So what should I do?
That's because you need RTF-enabled Swing component to visualize various text properties.
JTextArea is visualizing only plain text. Use JEditorPane or JTextPane instead.
Okay, I'll admit - the title is not the most descriptive/helpful but I couldn't really think of a better way to put it, which is probably also why I couldn't find an answer when I was searching.
Basically, I'm making a basic MS Notepad like text editor and I want to add two JButton's to make a JTextArea's font Bold and Italic. I need someway of indicating whether the text is currently bold and/or italic like in MS Office programs where the background of the buttons are orange when text is bold, italic or underlined - only I can't seem to change the background of the button. I think this is due to the fact that I am using the operating system's look and feel, but that information still doesn't solve my problem.
So does anyone have any suggestions on how I can provide some feedback as to whether the text is bold and/or italic through the JButton like in Microsoft Office Word? Thanks in advance.
Hmm...sounds like you'll want to make use of the JToggleButton class.
You can set the background color of a JButton object with the method setBackground.
So:
JButtonName.setBackground(Color.ORANGE);
In addition to David's and mre's comments, JButtons and by extension JToggleButtons are not opaque by default, so the background is not painted. In addition to setting the background color, you also need:
jButtonName.setOpaque(true);
I have a project, I'm creating an application in Java and I need text editor with sample functions (Bold, Italic, Size, Align, Undo, Redo).
So is there a class in Java for this purpose or a tutorial to show how to develop it?
I tried to style text in a jTextPane but when I change a word in bold, the whole text become in bold.
I want just to stylize the selected text only.
This should get you started: Editor based on JTextPane
Or this tutorial: How to Use Editor Panes and Text Panes
(source: oracle.com)
The Java Tutorial's TextComponentDemo illustrates many features such as undo/redo, styling selected text and binding key strokes to editing actions.
I'm trying to make it so when I tab to some text fields on in my JFrame the data in the text field will be highlighted. I thought I had done this in the properties before but I am not seeing the option now. Does anyone know how to do this?
You could use a FocusListener to work out when your field has focus (tutorial here).
Decide whether you want to select the text in the field, or whether you just want to change the background color. It's not quite clear what you mean by highlight.
