Java Question. Autocomplete and other things.

Question

I'm currently learning Java so i'm a beginner. I tried to make a program with the JOptionPane Output. I know that i need to import the javax.swing but i've seen that when you write JOptionPane it automatically get's imported, unluckily that does not happen for me. Does somebody knows why?

And also , is there a combination of keys for seeing the autocomplete window?

Answer 1

Which IDE do you use? IDE's usually provide the auto-import feature. It recognizes classes/methods you haven't imported yet and suggests you missing import statements.
Ctrl + Shift + O imports packages automatically in IntelliJ. There have to be equivalent key combinations in other IDE's. Search for them in Google.
This feature might be disabled in your IDE.
