Get the methodName and className from a line of code

I am writing a parser that takes as an input a file like :

Testabc:10 20
Testxyz:100 30

This file is the format ClassName:LineNumber TimeTakenToExecute it. My parser takes a bunch of these files and gets the method called at ClassName:LineNumber and outputs another file of the format :

Say line 9 and 10 of Testabc looks like :

Utils utils = new Utils();
utils.getName()

then the output of my parser should be :

Utils.getName() 20
Manager.getPassword() 30

I can get the string attached to the line in a class (i.e from Testabc:10 I can get utils.getName()).

I can also get a list of methods in my code directory and map it to a class (Eg map : getName:Utils). But it will not work for duplicate method names/overridden methods/classes that extend interfaces (In this case I want the method to show the implemented class name and not the interface name).

Is there any way I can get this information through reflection? i.e., get the class name and method name from a line of code?
