In JFrame Form I have added a jTextArea and added a text into it, while still in design mode. But when I run the form I want the text to be invisible, which is not happening. I checked the properties of the JTextArea but I am not really sure how to change the visiblity of the text..
For clearing the JTextArea filed you need to set its text as empty.
For this you need to see JTextArea#setText as null or "".Try this code at the execution of your application.
jTerxtAreaObject.setText("");
Set the color of the text as the same color as the background.

I want to make selected text of jtextarea underline while clicking a spicified button. this task I have accomplish in jtextpane but I need it in jtextarea any suggestions please.
Use a JTextPane (or JEditorPane), where you can use HTML tags to accomplish that.
The text of a JTextArea cannot be formatted in parts, as indicated here, for example:
A JTextArea is a multi-line area that displays plain text.

You can add a Highlighter to the text area and use a custom Painter to highlight the text. The default painter paints the entire background of the highlighted text, but you can customize the Painter to do whatever you want.
Check out Rectangle Painter for a couple examples of creating your own custom Painter.
Without resorting to wrapping a GWT TextArea in a separate DIV, how to add a search icon/magnifier icon inside the text area?
No, Not possible.Text area is not a normal Widget.
GWT's TextArea maps directly to a HTML TextArea thats why you can only set text to it. The only thing you can do ist create a Grid/VerticalPanel/HorizontalPanel and put in each cell a separate TextArea.

I have a JTextField that a User and an Admin update to try and solve a problem that a user may have. Although when I setText(conversation) to the JTextField the text starts in the middle and when it goes to the end of a line it does not go to a different line. Can I set the JTextField so that text begins at the top? and when the user/admin gets to the side of the text field it goes to another line? I have tried looking this up everywhere and can not find an answer
here is a picture of the window with the conversation text field
Just noticed that you are using a JTextField. JTextField is a single line and will hence print the text that appears to be center aligned. You should be using a JTextArea instead that that is multi-lineand it will solve your problem
I have a few text areas that are filled with loops of information. Is it possible to make it 'jump' or scroll back to the top automatically after the loop has completed, so that the user sees it from the start and not the end?
You can use setCaretPosition() to set the cursor at position 0 of the TextArea. That usually works for me.
Use setUpdatePolicy with NEVER_UPDATE, and make sure the setUpdatePolicy comes before setting any text to the JTextArea. In my example I initialize a JTextArea without any text and call setUpdatePolicy right after.
JTextArea jTextArea = new JTextArea();
((DefaultCaret)jTextArea.getCaret()).setUpdatePolicy(DefaultCaret.NEVER_UPDATE);
I have solved this problem by creating a new TextArea which acts as a sort of buffer (and isn't displayed). The loop writes to this area and when completed gets the text from that and sets it to the required TextArea.
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.
