Class.getMethod with variable args

[Stephen Upton]

Hi,

I'm struggling to find the right syntax to invoke a method using reflection that uses variable argument list, e.g.,

class A {
public void myMethod(int x, String... otherargs) {...}
etc....
}

then

Method m = AasClass.getMethod("myMethod", ???);
m.invoke(Ainstance, ???);

hope that's clear
thank you

Hi Stephen,

Welcome to JavaRanch!

varargs is just syntactic sugar for a final argument of array type; i.e., the "real" declaration of your method is

public void myMethod(int x, String[] otherargs) {...}

So you want...

Method m = AasClass.getMethod("myMethod", new Class[] {Integer.TYPE, String[].class});

Or since getMethod() now uses varargs itself, you can get rid of the "new Class[]" part and just use:

Method m = AasClass.getMethod("myMethod", Integer.TYPE, String[].class);
