java - 日期和匹配月份的数组

Question

我目前正在学习软件开发类(class)，并被分配了一个任务，我遇到了一些麻烦，如果有人能提供帮助，我将不胜感激……顺便说一下，这是在 Java 中完成的任务:

编写一个访问两个数组的程序。一个数组将保存月份名称，另一个数组保存每个月的天数。

当用户输入月数时，程序将返回月名和天数....

这是我到目前为止输入的代码，但有点卡在最后....

    int number;
    number = Integer.parseInt(jTextField1.getText());
    int [] Days;
    Days = new int [12];
    Days [0] = 31;
    Days [1] = 28;
    Days [2] = 31;
    Days [3] = 30;
    Days [4] = 31;
    Days [5] = 30;
    Days [6] = 31;
    Days [7] = 31;
    Days [8] = 30;
    Days [9] = 31;
    Days [10] = 30;
    Days [11] = 31;
    jTextField3.setText(String.valueOf(Days));


    String [] Month;
    Month = new String [12];
    Month [0] = "January";
    Month [1] = "February";
    Month [2] = "March";
    Month [3] = "April";
    Month [4] = "May";
    Month [5] = "June";
    Month [6] = "July";
    Month [7] = "August";
    Month [8] = "September";
    Month [9] = "October";
    Month [10] = "November";
    Month [11] = "December";
    jTextField2.setText(String.valueOf(Month));

更好的版本是使用 Month 类:

public class Month {
    private String name;
    private int days;

    public Month() {}
    public Month(String name, int days) {
        this.name = name;
        this.days = days;        
    }

    public String getName() {
        return name;   
    }

    public String getDays() {
        return days;   
    }

}


Month[] months = new Month[12];
months[0] = new Month("January", 31);
// ...

int n;
// ...user read from keyboard n from 1 to 12 month;

// set month info
jTextField.setText("In " + months[n - 1].getName() + " are " + months[n - 1].getDays() + " days!");
