控制台需要输出用户信息

Question

我真的很难执行我正在尝试创建的这个程序。我希望用户能够输入他们想要的尽可能多的信息，并且我的程序可以存储这些信息，直到用户键入单词 "quit"。一旦用户键入这个词，我希望程序结束并在控制台中列出用户输入的所有内容。我知道我需要使用数组，但我并不擅长使用它们。

我已经完成了用户可以键入 "quit" 并且程序将结束的部分，但我不确定如何让它在控制台中列出所有内容。

这是我遇到错误的地方：

import java.util.Scanner;
public class Requirement1B {
public static void main(String[] args) {

Scanner scan = new Scanner (System.in);
String name, entry, exit = "";

System.out.println("Please Enter Your Name");
name = scan.nextLine();
System.out.println("Players Name: " + name);

while (true) {

    Scanner scan1 = new Scanner(System.in);
    System.out.println("Please Enter a Game Name, time spent playing the game(in Minutes) and your points"
            + " in this format...\t Game:Time:Points" ); 
    entry = scan.nextLine(); //this is the information I want show on the console once "quit"

    Scanner scan2 = new Scanner (System.in);
    System.out.println("If You Are Done type \"quit\" if not press return");
    exit = scan.nextLine();

    if (exit.equals("quit")) {
        break;
    } // This Works. but doesn't show information.

}

我希望信息如何在控制台中显示的示例是：

"Users Name" 例如Whosebug

"----------------------------------"-------------------------"

"Game:Time:points" 例如"COD:120:12345"

"Game:Time:points" 例如"FIFA:120:12345"

"Game:Time:points" 例如"GTA:120:12345"

"Game:Time:points" 例如"MINECRAFT:120:12345"

在此先感谢您的帮助。

Answer 1

你需要的数据结构是列表：

List<String> games = new ArrayList<>();
String game;
Scanner in = new Scanner(System.in);
while ((game = in.nextLine()) != null) {
  if (game.equals("quit")) {
    // process 'games' however you want, for example
    for (String g : games) {
      System.out.println(g);
    }
  } else {
    games.add(game);
  }
}

    public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    String line = "";
    String exit = "";
    boolean isInput = true;
    StringBuilder sb = new StringBuilder();
    System.out.println("Please Enter a Game Name, time spent playing the game(in Minutes) and your points"
            + " in this format...\t Game:Time:Points");
    System.out.println("If You Are Done type \"quit\" if not press return");

    while (isInput) {
        line = scan.nextLine();
        sb.append(line);
        if (line.equalsIgnoreCase("quit")) {
            isInput = false;
        }
    }
    System.out.println("Your String : " + sb.toString());
}
/*
 * Please Enter a Game Name, time spent playing the game(in Minutes) and
 * your points in this format...    Game:Time:Points If You Are Done type
 * "quit" if not press return Output : Game1: Points Game2: Points2 quit
 * Your String : Game1: PointsGame2: Points2 quit exit loop
 */

控制台需要输出用户信息

Console needs to output user info

java

eclipse

arrays

console

output
