How to get string name of a method in java?

Question

How can I find out through reflection what is the string name of the method?

For example given:

class Car{
   public void getFoo(){
   }
}
         


        

Answer 1

You can get the String like this:

Car.class.getDeclaredMethods()[0].getName();

This is for the case of a single method in your class. If you want to iterate through all the declared methods, you'll have to iterate through the array returned by Car.class.getDeclaredMethods():

for (Method method : Car.class.getDeclaredMethods()) {
    String name = method.getName();
}

You should use getDeclaredMethods() if you want to view all of them, getMethods() will return only public methods.

And finally, if you want to see the name of the method, which is executing at the moment, you should use this code:

Thread.currentThread().getStackTrace()[1].getMethodName();

This will get a stack trace for the current thread and return the name of the method on its top.
