Java中怎么把字符串数组转为整形数组

[yangjinCK]

String [] str={"11","22","33"};
int [] num;

请教下怎么把字符串数组里的数据转在整形数组里面

[knightzhuwei]

import java.util.Arrays;

public class Test {
	public static void main(String[] args) {
		String [] str={"11","22","33"}; 
		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));
	}
}
