我意识到我需要一个整数数组.Java 中的 Math 函数的哪一部分可以让我轻松地做到这一点?数字列表将按顺序从 1 到 100.

I realize that I need an array of integers. What part of the Math functions in Java will allow me to easily do that? The list of numbers will be from 1-100 in sequential order.

推荐答案

我不太明白你为什么需要数学函数.

I don't quite understand why you need the Math functions.

这行得通:

List<Integer> age = new ArrayList<Integer>();
for (int i = 1; i <= 100; ++i) {
    age.add(i);
}
JComboBox ageComboBox = new JComboBox(age.toArray());
