我如何获得由 ; 分隔的多个双输入？从一个 JtextField 并将它们存储在一个数组中？

Question

我在 JAVA 中遇到了这个问题，我需要将多个双打分开；从单个 jTextField 每次单击保存按钮时将它们存储到一个数组中，我还想设置 5 个输入的限制，例如： 12;13;14;15;16 进入我的 jtextfield 然后我希望它停止，直到我点击保存然后它变成空白等等
抱歉，如果我不够清楚，这是我第一次来这里，而且我在 JAVA.
方面还是个初学者提前致谢！
这是我目前的实际代码，没什么了不起

Answer 1

您可以使用 getText() 方法获取 JTextField 文本，然后您可以使用 StringTokenizer st = new StringTokenizer(textField.getText(),";") 标记该字符串。然后你可以存储“;”之间的每个字符

int i=0;
while (st.hasMoreTokens()) {
    array[i] = st.nextToken();
    i++;     
}

请记住，数组的大小是静态的，并且在声明和初始化数组时定义。您可以使用其他数据结构，例如 ArrayList<T>。

希望这就是你想要的。
