// This is the call of the method, giving two objects
addRek(wurzel, blatt);
// This is the important part
public void addRek(Blatt refer, Blatt blatt) {
refer = blatt;
// What I originally intended to do was to write the reference to 'blatt' into 'wurzel'.
// What he does, however, is write the reference into 'refer', which is obviously lost after the method ends
// What I need is a way to access the variable behind refer
}
// This is of course not the whole class, and I could rewrite it so this problem doesn't present itself, but if there is a way of doing it'd, that'd be nice.
