你如何让你的程序打印出用户输入的值的数量？

Question

For example, if a person entered the numbers 22,44,55,33,77,443. It would print out "6 numbers have been entered".

Answer 1

Perhaps you're looking for String.split , for example:

String input = "22,44,55,33,77,443";
System.out.printf("%d numbers have been entered\n", input.split(",").length);
