Answer 1

String str = "3,4,5,6";
String[] strArr = str.split(",");
int[] intArr = new int[strArr.length];
for (int i = 0; i < strArr.length; i++) {
intArr[i] = Integer.parseInt(strArr[i]);
}

Answer 2

public static void main(String args[]) {
String str = "3,4,5,6";
String[] subs = str.split(",");
int a = Integer.parseInt(subs[0]);
int b = Integer.parseInt(subs[1]);
int c = Integer.parseInt(subs[2]);
int d = Integer.parseInt(subs[3]);

}

这个按“，”号拆分然后是一个数据接下来就是遍历数组了用这个split(String regex)

String[] arry = str.split(","),返回一个String数组 。 然后 for循环遍历
