Java中把字符串数组转换成整型数组 (未测试)

public class Test {    public static void main(String[] args) {        String [] str={"1","2","3"};         int [] num=new int[str.length];        for(int i=0;i<num.length;i++){            num[i]=Integer.parseInt(str[i]);        }        System.out.println(Arrays.toString(num));    }}
