学习java的最佳方法是什么

Question

I originally had a bunch of code up here but now that I am somewhat more familiar with the world of programming (no expert by any means), I would like to know from a community's perspective, the best approach to learning java the practical way, I have since (the original post) taken formal classes in C and C++, but would like to give java another chance. I now know how to understand the java docs (at least somewhat), so that's not what I am asking, but rather what are some stepping stones or hurdles to progressively over come when learning java or any new language for that matter?

Answer 1

You are doing this Passenger p = new Passenger(); .

But I cannot see any class named Passenger in your code. Correct the class name.

Your code is really incomplete. survivalToll() method is also not defined.

Variable survivor not declared. Many more are there.

You are confused with the constructor as method. I think you code chunk should be replaced by

class Passenger {


    //private String[] lastNames;
    private Scanner scan;
    private String path;

    private ArrayList<String[]> passengerList;

    public Passenger(String filePath) {
        this.path = filePath;
        this.passengerList = new ArrayList<String[]>();
        this.readFile();
    }}
