Can you help?

Hi,

My question is this:

My work has given me a in use (working) file in which they want me to change the head office address. The file .class so obvioulsy it is a compiled java file thus its source can only be read using a decompiler that I have done.

I am using DJ Java Decomipler and have opened the file and have made the change required. It was a simple change of address.

The problem now is how to save the change? I can save the file as .java or .jad. And if I try to compile the .java file I get the 2 errors which I am not sure.

Isnt there any way where I can simply save it back to .class?

What should I do? I want to save the change.

Thanks.

There is a lot wrong with your code. For starters, try this code by itself and see how that works for you. Then go from there:

public static void main(){
int age = enterAge();
JOptionPane.showMessageDialog(null, "You are " + age + " years old.");

}

public static int enterAge(){
return Integer.parseInt(JOptionPane.showInputDialog("Your Age?"));
}

Also, you are making everything static. This can get messy, as you cannot then make class variables easily. I prefer to do it this way:

class SomeClass{
public static void main(String[] args){
new SomeClass();
}

public SomeClass(){
//This is the constructor
int someInt = getAnotherInt();
}

public int getAnotherInt(){
return 5;
}

I hope you get the idea there. Lastly,

age = enterAge(/*int*/age);
That line is a mess. You need to declare type before you can assign, and you NEVER declare type inside a parameter, and that method [enterAge()] doesn't even take any parameters to begin with. It should look more like this:
int age = enterAge();

Good Luck

Oh good...it's not just me then. I thought I was going mad for a second there!

Anyway, on your topic, um...you really don't have the source code for this project? That's not a Good Thing...and decompiling and then recompiling just smacks of a truly dreadful hack. This is production code?

Anyway, you need to compile the new java file, for which you need a java compiler.

I'd recommend that you find the creator/distributor of the code and get the source. Otherwise you're playing with fire with easy chance of things blowing up on you and possibly going against copyright and perhaps other laws.
