出于某种原因，在输入员工姓名时，插入点会跳过员工 1 并直接转到员工 2。但是，员工 3 及以后的员工似乎会正确输入。这是我的完整代码。忽略它的愚蠢，我做事非常规.import

Scanner#nextInt() does not consume newline characters, instead passing through to the loop that reads employee names.

name[i] = in.nextLine();

The first line in the iteration now will not block as it has already received input from the previous block.

Solution: add in.nextLine() prior to the second loop to consume the newline character.
