    Default What is the difference between next() and nextLine()?

    Can you tell me the difference between those two?
    I have noticed that when i use next(), for example:
    String entered_name=scan.next(); , I can enter only one word, this method doesn`t accept two words separated by space
    On the other hand when i use nextLine(), for example:
    String entered_name=scan.nextLine(); , I am not allowed to enter anything, the program just skips this step and entered_name remains empty.

    What I need is to be able to enter several words separated by space.
    What is the difference between those two and what is the solution to my problem?

    Thanks in advance!

    Have you read the Scanner class's API doc? Do you have any questions about the descriptions there of those two methods?
    Please post your questions here.
    A token is a string of non blank characters surrounded by white spaces.
    The current line ends with a newline character.

    Can you post the program you are having trouble with?

    What I need is to be able to enter several words separated by space.
    Use the nextLine method to read all of what is on the current line. It is possible for the current line to only have a newline character which would return an empty string.
