Question

我有一个程序从命令行接收用户的输入。令人讨厌的是，当我第一次使用扫描仪时，输入的文本会在下一行（System.out.println之后）进行。但是，所有其他时间它与System.out.println在同一行。

代码：

//Create a scanner
Scanner input = new Scanner(System.in);

//Gets type
System.out.println("--Television Show or Film (t or f): ");
String type = input.nextLine();
input.close();

输出：

--Television Show or Film (t or f): 
t

Desierd输出：

--Television Show or Film (t or f): t

感谢任何帮助。另外，我正在使用Eclipse Console。

Answer 1

使用System.out.println而不是{{1}}？

Answer 2

尝试：

   System.out.print("--Television Show or Film (t or f): ");
   String type = input.next();

Answer 3

原因是您使用println System.out版本的print。仅使用System.out.print("--Television Show or Film (t or f): ");：Sub FindMatches() Dim oldrow As Integer Dim newrow As Integer For oldrow = 4 To 14 For newrow = 3 To 20 If Cells(oldrow, 12) = Cells(1, newrow) And Cells(oldrow, 13) = Cells(newrow, 1) Then 'date and brand If Cells(1, 14) = Cells(newrow, 2) Then Cells(newrow, 3).Value = Cells(oldrow, 14).Value ' m1 End If If Cells(1, 15) = Cells(newrow + 1, 2) Then Cells(newrow + 1, 3).Value = Cells(oldrow, 15).Value ' m2 End If If Cells(1, 16) = Cells(newrow + 2, 2) Then Cells(newrow + 2, 3).Value = Cells(oldrow, 16).Value ' m3 End If If Cells(1, 17) = Cells(newrow + 3, 2) Then Cells(newrow + 3, 3).Value = Cells(oldrow, 17).Value ' issue End If If Cells(1, 18) = Cells(newrow + 4, 2) Then Cells(newrow + 4, 3).Value = Cells(oldrow, 18).Value ' repack End If If Cells(1, 19) = Cells(newrow + 5, 2) Then Cells(newrow + 5, 3).Value = Cells(oldrow, 19).Value ' extra End If If Cells(1, 20) = Cells(newrow + 6, 2) Then Cells(newrow + 6, 3).Value = Cells(oldrow, 20).Value ' wastage End If End If Next newrow Next oldrow End Sub

Java如何在同一行上获取scanner.nextLine（）？
