Disabling part of a method

[juru]

Well, i want to know if there is a way to disable part of a method(.class) rather than decompiling the class and fixing the errors and all.
For ex:

public method test() {
try {
	    is_17_ = String.methodE(is_16_, true);
	} catch (RuntimeException runtimeexception) {
	    throw Test.method1D(runtimeexception,
				      (""));
	}
}

and i want to disable the Throw, what would i have to do?
EDIT:
i would like it to look like this:

public method test() {
try {
	    is_17_ = String.methodE(is_16_, true);
	} catch (RuntimeException runtimeexception) {
	is_B_ = new byte[100];
	    //throw Test.method1D(runtimeexception,
				      (""));
	}
}

And if anyone could help me do that in bytecode, it would also be appreciated .

So, let me guess that this is decompiled code that you're messing with. If so, I'd go to the folks who coded it and ask to get the source code. You'll have a much easier time changing that.

No, that is the example, I am the one who has the src(its a basic applet) i made it last night, because i wanted to learn how to disable somepart of a method

OK,... then why don't you post the whole class if it's not too big, or shorten it to the smallest possible amount of code that still compiles and still shows your problem. Please adjust your variable and method names, and fix your indentation to make everything readable. Also, please specify exactly what you are trying to do here and why. You stated something about removing a catch block which sounds a bit fishy .... why is there a catch there in the first place, possibly because there's a method within the block that can possibly throw an exception, and you may need the catch,... I'm not sure. Any way, the more information and readable code you can provide, the better we'll understand your problem.

Why is the class src so important? disabling a method, can you not show me how to do it with that method itself?

Your code as written makes no sense, isn't compilable in the least (String method "methodE"?), and makes it hard to understand your question out of context. Sure you can often place a portion of a methods code within an if block and use a boolean variable to control its execution, but I've not seen that done with a throws clause. I guess it all smells funny to me.

You have the source, but want to manipulate bytecode? Sounds almost certainly like a fudgy workaround for something-or-other. What is that something-or-other? Simply disabling the throwing of a runtime exception isn't going to magically fix some bug you've got, if that's what you're thinking

[juru]

No, i wanted to experement with that, for example, whatever the applet sends out can be changed by a class. (like..1+1=2, the output can be changed so 1+1=6, something similar)

You mean "can I hack bytecode to do something other than what it was compiled to do?"

To which the answer is "yes" with suitable effort and skill
