string nextline

The key to the use of nextline () and Next () is that when the next () method encounters the first valid character (not a space, newline character), the scan begins, and when the first delimiter or terminator (space or line break) is met, the scan

I personally prefer to use the scanner scanner when I implement the input of the character window, which is relatively simple to operate. In the process of writing, I found that there are two ways to implement string input using scanner, one is next

First look at the explanation:nextint (): It is reads the int value, Nextint () places the cursor in the same line after reading the I Nput.Next (): read the input only till the space. It can ' t read words separated by space. Also, Next () places

Pipeline SC = new pipeline (system. In ); Int conditon2 = SC. nextint ();Switch (conditon2 ){Case 1:For (INT I = 0; I If (theory [I] = NULL ){System. Out. Print ("Enter the course number :");Courseid = SC. nextline ();System. Out. Print ("Enter the

        in the implementation of the character window input, many people prefer to use the scanner scanner, it is easier to operate. In the process of programming, I found that there are two ways to implement string input with scanner, one is next (

First, we introduce, in the Java language, for string input, because the scanner.next () function can not enter the space and carriage return, at this time, we have to use scanner.nextline () to solve such problems ，In the process of use, we will
