java - 使用 Scanner 的字符串数组

Question

在我的程序中，我需要创建一个字符串数组，该数组允许用户使用扫描仪在控制台中一个接一个地输入最多 100 个文本字符串。然后，当用户键入单词“stop”时，我需要程序能够显示键入的所有字符串 (<=100)。

我不希望有人为我编写整个程序，但也许只是一些提示？

我确信这是非常基本的，但我对 java 很陌生，我不能让这个模块失败，非常感谢任何帮助!

我希望这有帮助!

String[] array = new String[100];
String str = null;
Scanner sc = new Scanner(System.in);
for (int i = 0; i < 100; i++) {       
    str= sc.nextLine();
    if(str.equals("stop")) {
        break;
    }
    array[i] = str;
}
