如何从ArrayList获取secound行

Question

    package Nauka;
    import java.util.ArrayList;
    import java.util.Arrays;
    import java.util.Random;

    public class NaukaGamy {
    public static void main(String[] args) {
        ArrayList<Akord> gamy = new ArrayList<Akord>();

        gamy.add(new Akord("C dur\n\n","  c', d, e, f, g, a, h, c"));
        gamy.add(new Akord("C moll\n\n","  c, d, es, f, g, as, b"));

        System.out.println(gamy.get(1));

结果是：Nauka.Akord@7852e922

我要将secound line（C moll \ n \ n＆＃34;，＆＃34; c，d，es，f，g，as，b）作为解决方案。怎么做？

Answer 1

您需要在班级toString()中覆盖Akord方法。例如，

public class Akord {
    @Override
    public String toString() {
        return /*your fields to String*/;
    }
}
