數組中存放對象之java中定義類數組存放類

public class ClassArrayDemo {
    int age;
    String name;

    ClassArrayDemo(int age, String name) {
        this.age = age;
        this.name = name;
    }

    @Override
    public String toString() {
        return "[" + name + "," + age + "]";
    }

    public static void main(String[] args) {
        ClassArrayDemo[] t = new ClassArrayDemo[3];
        t[0] = new ClassArrayDemo(18, "zs");
        t[1] = new ClassArrayDemo(19, "ls");
        t[2] = new ClassArrayDemo(20, "ww");
        for (int i = 0; i < t.length; i++) {
            System.out.println(t[i]);
        }
    }
}

結果：

[zs,18]
[ls,19]
[ww,20]
