How to generate a void method in IntelliJ IDEA?

To create a new method from usage in the code like:

...
someMethodName()
...

AltEnter on the red code:

It's also possible to type void methodName() and use Complete Statement (CtrlShiftEnter), it will become:

void methodName() {
    |
}

You could create your own Live Template as @Makoto answered, but programming by intention seems to be more natural. When you don't have a method, you write code that will use it, then create the method from the intention action - this way IDEA will generate the method signature automatically according to the parameters and return type in the not yet existing method usage, like String result = someMethod(stringParam);.

Finally, it is worth nothing that in IntelliJ IDEA main() method can be generated using psvmTab.

IntelliJ IDEA 15

Generate a main method

• Default:

  Type psvm (public static void main) > press Tab

• Use the template from Eclipse (main instead of psvm)

  • File > Settings or press Ctrl + Alt + S

    

  • Editor > Live Templates

    

  • From the right side, click on the "+" sign > Live Template

    

  • Add the following details:

    • Abbreviation: main
    • Description: main() method declaration

    • Template text:

      public static void main(String[] args){
        $END$
      }
      

      

      You will see the new template added in Others.

  • Click on Define

    

  • Select Java > Press on OK

    

  • Type main in your Java code > press Tab

Generate a void method

• Type your method name followed by parentheses (+ the arguments, if you use them) - E.g.: m() or m(1,2) > Press Alt + Enter > Click on "Create method ..." (or press Enter if it is already selected)
