    I was wondering if there was a way to use the System.out.printf statement to left justify a String and set aside a number of spaces that the user inputs? for example I know that if you want a String left justified and 5 spaces allocated for it it would be printf("-%5s", string) but is there a way to have ("-%'spaces's", string) where spaces is an integer input by the user?

    this is what I have:
    System.out.printf("| -%", width, "s : %1c\n", _line1, "|");
    but it gives a runtime error.

    You can do this by dynamically generating the format string. Here is an example of how you could do this in C:

    char string[] = "123";
    char format[50];
    int spaces = 5;
    sprintf( format, "-%%%ds", spaces );
    printf( format, string );
