Madlibs 游戏的代码，如何存储每个输入而不是仅存储最后一个输入{JAVA}-解网

问：

所以基本上这是我下面的代码，要求用户根据字符串输入一个名词或动词，直到字符串完成，但是当它输出编辑的字符串时，它会输出最后一个动词和用户输入的最后一个名词。我的问题是，有了这段代码，有没有办法将每个输入保存在字符串中的相应位置，然后移动到下一个输入？ ps：我不被允许使用数组。

import java.util.Scanner;
public class MadLibsProject
{
    public static void story()
    {
        Scanner in = new Scanner(System.in);
        String noun = "";
        String verb = "";
        String story = "The Little Noun And The Old Noun By Shel Silverstein \nSaid the little boy, "+
        "sometimes I drop my noun. \nSaid the little old man, I verb that too.\nThe little boy whispered, I verb my noun.\n"+
        "I do too, laughed the old noun. \nSaid the little boy, I often cry. \nThe old "+
        "man nodded. So do I. \nBut worst of all, verb the noun, "+
        "it seems grown-ups don’t pay attention to me. \nAnd he felt the warmth of a "+
        "wrinkled old hand. \nI verb what you verb, said the little old noun.";
        String update ="";
        String noun1 = noun;
        String verb1 = verb;
        for(int i =0;i< story.length()-4;i++)
        {
            String madlib = story.substring(i,i+4);
            if("noun".contains(madlib) || ("Noun".contains(madlib)))
            {
                System.out.println("Please enter a noun");
                noun = in.next();
                
            }
            
            
            else if("verb".contains(madlib))
            {
                System.out.println("Please enter a verb");
                verb = in.next();
                verb1 = verb;
            }
            noun1 = noun;
            verb1 = verb;
            update = store(noun1,verb1);
            
        }
        
        System.out.print(update);
    }
    public static String store(String noun,String verb)
    {   
        // for int i = 0;i < story.length()-4; i++
        // madlib = story.substring(i,i+4)
        // noun.contains mmadlib
        String story = "The Little "+ noun+" And The Old "+noun+" By Shel Silverstein \nSaid the little boy, "+
        "sometimes I drop my "+noun+". \nSaid the little old man, I "+verb+" that too.\nThe little boy whispered, I "+verb+" my "+noun+".\n"+
        "I do too, laughed the old "+noun+". \nSaid the little boy, I often cry. \nThe old "+
        "man nodded. So do I. \nBut worst of all, "+verb+" the "+noun+", "+
        "it seems grown-ups don’t pay attention to me. \nAnd he felt the warmth of a "+
        "wrinkled old hand. \nI "+verb+"  what you "+verb+", said the little old "+noun+".";
        return story;
        
    }
    public static void main(String[] args)
    {
        
        story();
        
        
    }

这是我现在的输出：输入：请输入名词名词1 请输入名词名词2 请输入名词名词3 请输入动词动词1 请输入动词动词2 请输入名词名词4 请输入名词名词5 请输入动词动词3 请输入名词名词6 请输入动词动词4 请输入动词动词5 请输入名词名词7 输出：小名词7 和老名词7 谢尔·西尔弗斯坦（Shel Silverstein）小男孩说，有时我会去掉我的名词7。小老头说，我也动词了5。小男孩低声说，我是动词5我的名词7。我也是，笑了老名词7。小男孩说，我经常哭。老人点了点头。我也是。但最糟糕的是，动词 5 名词 7，似乎大人不注意我。他感受到了一只布满皱纹的老手的温暖。我动词5你动词5，说小老名词7。your text

Java 循环方法

The Little =Noun= And The Old =Noun= By Shel Silverstein \nSaid the little boy, 
sometimes I drop my =noun=. \nSaid the little old man, I =verb= that too.\nThe little boy whispered, I =verb= my =noun=.\n
I do too, laughed the old =noun=. \nSaid the little boy, I often cry. \nThe old 
man nodded. So do I. \nBut worst of all, =verb= the =noun=, 
it seems grown-ups don’t pay attention to me. \nAnd he felt the warmth of a 
wrinkled old hand. \nI =verb= what you =verb=, said the little old =noun=.

然后，利用 StringBuilder#replace 方法添加值。

下面是一个示例。

Scanner in = new Scanner(System.in);
StringBuilder s = new StringBuilder(story);
String t;
for (int i = 0, j, n = s.length(); i < n; i++)
    if (s.charAt(i) == '=') {
        j = s.indexOf("=", i + 1);
        System.out.printf("Please enter a %s%n", s.substring(i + 1, j));
        s.replace(i, j + 1, t = in.next());
        i += t.length();
        n = s.length();
    }

此外，您可能需要检查它是否是大写的。

Scanner in = new Scanner(System.in);
StringBuilder s = new StringBuilder(story);
String t;
boolean u;
for (int i = 0, j, n = s.length(); i < n; i++)
    if (s.charAt(i) == '=') {
        j = s.indexOf("=", i + 1);
        t = s.substring(i + 1, j);
        u = Character.isUpperCase(t.charAt(0));
        System.out.printf("Please enter a %s%n", t.toLowerCase());
        t = in.next();
        if (u) t = t.substring(0, 1).toUpperCase() + t.substring(1);
        s.replace(i, j + 1, t);
        i += t.length();
        n = s.length();
    }
