我想在 println 中添加一個 function

Question

我正在嘗試將用戶輸入的名稱添加到 Java 的打印行中

 System.out.printf("According to your survey, an average of %.2f people rode the per day.",  media );

我想將它添加到文本“rode the...”的部分

Answer 1

首先獲取用戶輸入。 然后添加到打印行

String input = input.next();
 System.out.printf("According to your survey, an average of %.2f people" +input +  " rode the per day.",  media );

Answer 2

float media = 1.5f;
Scanner stdin = new Scanner(System.in);
System.out.printf("According to your survey, an average of %.2f people rode the %s per day.",
                  media,
                  stdin.nextLine());

運行上述代碼時，在輸入值並按ENTER之前，您不會看到任何打印內容。 例如，如果您輸入 Jabberwocky ¹ ，則將顯示以下行：

According to your survey, an average of 1.50 people rode the Jabberwocky per day.

¹ Jabberwocky
