如何解决如何使用Arrays.sort以字母顺序输出名称?
我基本上想使用Arrays.sort()方法按字母顺序对学生的姓名进行排序,然后将其写入名为class SomeWidget(QtWidgets.QWidget):
def __init__(self,parent=None):
super().__init__(parent)
layout = QtWidgets.QVBoxLayout(self)
# ...
的新文本文件中。我尝试这样做,但这会给我一个错误,我不知道我是在正确地起诉它还是放在正确的位置。
样本输入:
StudentNames
样本输出:
Select Your Class Size!
A 6x5 Classroom or a 3X10 classroom?
Enter '6x5' or '3x10' please!
6x5
Ok,so you have selected 6x5
Your classroom size looks like this:
XXXXXX
XXXXXX
XXXXXX
XXXXXX
XXXXXX
Now Enter The Number Of Students!
4
Enter the names of the 4 students!

The Student Names Have Been Sorted In An Alphabetical Order
The Names And Seat Location Of The Student Are As Follows:
Hussain Seat Location: (1)(1)
User Seat Location: (1)(2)
Jacob Seat Location: (1)(3)
Bob Seat Location: (1)(4)
我得到的输出: 选择您的班级人数!

基本上它什么都没有输出,我评论了我的A 6x5 Classroom or a 3X10 classroom?
Enter '6x5' or '3x10' please!
6x5
Ok,so you have selected 6x5
Your classroom size looks like this:

打印语句,这样它会显示我会得到的错误,但什么都不输出。
代码:
catch
解决方法
我相信BeUndead要说的是:
// Output the first names in the
for (int x = 0; x < numOfStudents; x++) {
names[x] = inp.next();
}
Arrays.sort(names); // This is where I put it,but it wouldn't work
for (int x = 0; x < numOfStudents; x++) {
if(containsx) {
if(row >= 6) {
column++;
row = 0;
}
}
else {
if(row >= 3) {
column++;
row = 0;
}
}
seats[x] = "("+Integer.toString(column)+")" + "("+Integer.toString(++row)+")";
bw.write(Arrays.toString(names)+" Seat Location: "+seats[x]);
bw.newLine();
}
但是,您必须了解,这只是一个起点。您的代码中还有更多错误。进行更改,检查结果,然后再次询问更具体的问题。
