Help needed on Reflection

[Joe Harry]

Guys,

I need to do something like this,

public void myMethod() {
  loggerFactory(---here I need to pass the method name...i.e. myMethod as String)
}

But I do not want to say it in double quotes...like "myMethod" is there any means of doing it using Reflection?

HelloClass.class.getMethod("METHOD_YOUWANTTOCALL", null).invoke(null, null);

HelloClass hcobj=new HelloClass();

hcobj.getClass().getMethod("METHOD_YOUWANTTOCALL", null).invoke(null, null);

Those parameters with NULLS are for Calling parameterized Methods

I think you did not understand my question, I want to print the name of the method inside the same method.

If you are the person who coded ( and also hard coded) the method and its body, why don't hard code the method name also...


Why you wanted to do like that..?

Jothi,

Do you want to log the name of the method automatically (as ENTER and EXIT for each methods) without hardcoding it explicitly?

[Charles Lyons]

Sounds to me like you want Thread.currentThread().getStackTrace() and take the first element. You can also get the method name like this:

Thread.currentThread().getStackTrace()[0].getMethodName()

This is a lot of work (and inefficient) for debugging purposes though - better to hard code it if you can.

The easiest way is to create (or throw) a new exception there and log that. Exceptions have the entire stack trace built in!

I was thinking on the same lines and I made use of StackTraceElement array and found the solution.

Thanks guys for the participation.

Raghavan,

You are right, I didn't want to hard code it. I mean the method name...

[Raghavan Muthu]

That's great! Hope you got the solution now

Whats the point in doint that....

Whats the point in getting programatically in the method itself...

You don't need to 'hardcode' the method name as Jothi quoted in his first post!

I simpley don't have to hard code the method names. I have a class where I have 50 odd methods and I really don't want to put anything in "double quotes".
