如何在java中从字符串数组中获取数字

public class Main {
    public static void main(String[] args) {
        String[] strArray = {"10", "20", "30"};
        int[] intArray = new int[strArray.length];

        for (int i = 0; i < strArray.length; i++) {
            intArray[i] = Integer.parseInt(strArray[i]);
        }

        // 打印结果
        for (int num : intArray) {
            System.out.println(num);
        }
    }
}
