Maybe the IDE provides something similar. Basically I have seeing
the IDE mock about the following:

    buf.append(x+y);

It then suggests to use:

    buf.append(x);
    buf.append(y);

And it also mocks about the following:

    StringBuffer buf=new StringBuffer();

It then suggests to use:

    StringBuilder buf=new StringBuilder();

But that + is internally realized via StringBuilder is a property
of javac with target >= 1.5 and not of the IDE.

See for example:
