Type mismatch: cannot convert from void to ArrayList

Question

Why am I getting this error for this code? I have the correct imports for ArrayList an Collections

private ArrayList tips;

public TipsTask(ArrayLi         


        

Answer 1

Collections.shuffle(tips) returns void. So you cannot assign this to an ArrayList()

What you want is

private ArrayList tips;

public TipsTask(ArrayList _tips){
    Collections.shuffle(_tips);
    this.tips = _tips;
}
