与重启程序相关并简化if else语句

Question

public static void main(String[] args) {
    String Day; // The user’s name.
    TextIO.put("This program is to tell you what to eat for today.");
    TextIO.put("\nBefore it starts, can you tell me what's the day today?");
    int count;
    int CCount;
    String Answer;
    CCount = 0;
    count = 0;
    do {

        if (Day.equals("Monday")) {

我想在这篇文章中提出两个问题（对不起，如果我的问题可能看起来很愚蠢，但我真的需要帮助）。

问题1：如何重新启动程序？在星座运势结束时，我想询问用户是否想重新开始重新开始。

问题2：是否有任何方法可以通过字母表简化代码？ 例如在我的代码中，我设置了MON和mon和Mon，是否有任何方法可以将这三者合并为一个？

Answer 1

我目前没有时间回答问题一，但问题二是

    if(day.toLowerCase().equals("mon")){ /*this makes the user input all lowercase,
                                        so you dont have to detect case anomalies*/ 
    }

根据UnknownOctopus的建议，你也可以使用

if(day.equalsIgnoreCase("mon"))

你会得到同样的效果。

修改 对于问题1，您需要创建一个名为wantsToPlay的布尔值或类似的布尔值，并将其设置为true（boolean wantsToPlate = true;。 然后你把你的程序的其余部分放到一个说

的while循环中

while(wantsToPlay){
//program
//ask user if they want to play again
//if input is yes or yay or whatever then{
//wantsToPlay = true;
//}else{
//wantsToPlay = false;
}
