//To improve on style, simplicity and maintainability I would break up this function with 4 nested ifs into separate functions

public boolean  f(){

        z();
    }
    else{
        s();
        return false;
    }
}

public boolean z(){
    if(B){
        y();
    }
    else{
        t();
        return false;
    }
}

public boolean y(){
    if(C){
        x();
    }
    else{
        u();
        return false;
    }
}

public boolean x(){
    if(D){
        w();
        return true;
    }
    else{
        v();
