    You tell us what's wrong...does it compile? Are there exceptions? Does it misbehave? Please read the link in my signature entitled 'getting help', and please wrap your code in the code tags

    for ( {
    out.print(">")
    That doesn't seem valid to me.

    String input = keyboard.next();
    String playername = "Player";

    String input = input;

    It isn't a good idea to have the same variable name "input".

    Change one of them to "input2" otherwise you'll probably get an error saying that input was already defined.

    You don't, I don't think you do anyway, have a class variable called "out". I think you're looking for

    System.out.println("Welcome " + input);

    Also, if you're looking for a full name, then use nextLine() instead of next(). next() goes till it finds a space.

    A for loop goes like this:


    for (variable_type variable = some_value; variable < someOtherValue; variable++)

    or that's one of the ways it could go.

    If you want to print out n ">" then you could

    for (int i =0; i < n; i++)
    {
    System.out.println(">");
    }

    String input = input; // is not acceptable because... input variable is already there...

    it gives compile error......at this point ....

    if we change String input1 = input;System.out.println(""+output1);

    the code will run fine output is ===

    Welcome,Player,to 0verload.
    Type your name,player
    > //cursour waits here for user input ... if u give input like uname...than output
    Welcomeuname


    modified code

    import static java.lang.System.out;
    import static java.lang.System.*;
    import java.util.Scanner;

    public class game {
    public static void main(String[] args) {
    System.out.println("Welcome,Player,to 0verload.");
    System.out.println("Type your name,player");
    for ({
    out.print(">");
    Scanner keyboard = new Scanner(System.in);
    String input = keyboard.next();
    String playername = "Player";
    String input1 = input;
    out.println("Welcome " + input1);
    }
    }
    }


    note :: playername variable is neverused ... and .. unused import system.lang
