我在JAVA中遇到这个问题,我需要将多个双打分隔开;从单个jTextField并将其存储到数组中,每次单击“保存”按钮时,我还想设置5个输入的限制,例如:
12; 13; 14; 15; 16放到我的jtextfield中,然后我希望它停止,直到单击“保存”,然后它变成空白,依此类推
抱歉,如果我不太清楚,这是我第一次来,我仍然是JAVA的初学者。
提前谢谢!
这是我目前的实际代码,没什么

答案 0 :(得分:0)
您可以使用getText()
方法获取JTextField文本,然后可以使用StringTokenizer st = new StringTokenizer(textField.getText(),";")
标记该字符串。然后,您可以在“;”之间存储每个字符。
int i=0;
while (st.hasMoreTokens()) {
array[i] = st.nextToken();
i++;
}
请记住,在声明和初始化数组时,数组的大小是静态的并且已定义。您可以使用其他数据结构,例如ArrayList<T>
。
我希望这就是你想要的。
