I've just discovered that if you type sysout then hold ctrl and press space it changes to System.out.println()
you can also indent the code properly.
select the code you want to format and press ctrl +shift+ 'F'
this will indent your data properly.

How to make shortcut to invisible menu item in Java
(1 answer)
Closed 5 years ago.
For most shortcuts, I add the action to the toplevel JMenu and provide the shortcut to the JMenuItem using setAccelerator(..). How do I make a global shortcut for an action without adding it to the menu?
This question already has an answer here, but I had trouble finding it because I was asking it differently.
As pointed out there, look for getInputMap / getActionMap in the Java keybindings tutorial.
I'll finish writing the question and mark it as a duplicate in case it helps to find it.

Problem with multi-line JTextField
(3 answers)
Closed 7 years ago.
I am doing a java program in Netbeans on windows os. I have a StringBuilder object
StringBuilder builder = new StringBuilder();
I have to append newline to it. I have tried
builder.append(“\n”);
builder.append(System.getProperty("line.separator"));
builder.append(System.lineSeparator());
It works when am displaying the output through System.out.println(builder);
But none of them works when am displaying it to a jTextField. What is the problem
As it is said in the following post: Newline "\n" in TextField java
JTextField or TextField (not sure which you're using) are for single lines only. If you want a basic multiline text display and you're using Swing, then use a JTextArea. If you're not using Swing, then please tell us which GUI library you are using as this is an important detail that your question should mention.

Hello I needed to know how do I uncomment out code in eclipse? I know Crtl+Shift+C will comment out a set of code how do I undo that?
Here You have all shortcuts for Eclipse:
http://www.shortcutworld.com/en/win/Eclipse.html
As You can see on point 7, its Ctrl + Shift + \.
As Already said, It is the same shortcut to comment and uncomment.
I Would like to precise the most important, IMHO, shortcut in Eclipse : ctrl + shift + l which lists all the shortcuts.
To comment any code, select it and press Ctrl + 7.
Use again to undo.

How We create a textfield behave as autocomplete by onkeypress evnet in java as Database is Mysql.
You should use a DocumentFilter (thanks MadProgrammer) instead of a KeyListener. The former is more reliable and easier to deal with.
Also instead of a JTextField you should use a JComboBox instead to show a drop down after the user begins typing.
Now I will not put the effort into creating some code for you since you did not show effort in asking the question.

I have taken one JFrame in which we have shown the information about our firm
there is one information(label) like:
website: www.samteksystems.com
I want that whenever I click on www.samteksystems.com it should display that website.
Please help me in this.
You can add a mouseListener to the label, and in the mouseReleased() method, you could use Desktop.browse() to visit the URL.
