Question

Similar to How to change "Generate Method Stub" to throw NotImplementedException in VS?, but for Eclipse instead of Visual Studio

Both NetBeans and Eclipse have a function that, if you declare a Java class to implement an interface but omit one or more methods, will automatically generate a stub method for you.

The difference is that the Eclipse version will do nothing, and return zero or null, e.g.

public String munge(String foo) {
    // TODO Auto-generated method stub
    return null;
}

The NetBeans version will throw an exception instead:

public String munge(String foo) {
    throw new UnsupportedOperationException("Not supported yet.");
}

which I prefer.

Is it possible to configure Eclipse to do this?

Go to Windows -> Preferences -> Java -> Code Style -> Code Templates. On the right you’ll see “Comments” and “Code”. Expand “Code” and the one you’re looking for is “Method Body”. Click “Edit…” and put whatever you want in there.
