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.
