Question

这可能是一个显而易见的问题，我不知道，但我无法在任何地方找到任何答案。所以，我有一个JTextField，它正在获取一些文本并将其放入一个字符串[]但我希望它变成一个int []。这是我的一些代码，但当然我有错误，我需要它转换为int []。关于我如何做到这一点的任何想法？

此外我遇到问题的代码是在按钮actionevent中，只是让你轻松找到它:)谢谢！

Answer 1

您必须自己实施。看起来应该是这样的：

public int[] stringsToInts(String[] strings){
    int[] ints = new int[strings.length];
    for (int i = 0; i < strings.lengths; i++){
        ints[i] = Integer.parseInt(strings[i]);
    }
    return ints;
}

Answer 2

没有神奇的内置功能。你需要自己实现一个。

只需创建int []并遍历string []并在每次迭代中解析字符串并将其保存到新的数组匹配索引中，完成后返回新的int []数组。

如何将String []转换为int []？
