    Question How do I get a line of text to print to the console from an input file??

    Hello! This is the last question I have about this program, then I'll leave you guys alone, I promise. All I need to know is how to print the line of numbers to my console/output file. How do I get the console to just print the numbers for Amarillo in that same order of "3 2 1 3 5" minus the negative number. So for example, I just want to say "The values entered are: " + whatever code I need. The rest of the code is perfect I just need that. Thanks so much!!

    Input file:
    Amarillo 3 2 1 3 5 -7
    Rochester 5 6 7 4 6 -2
    Albuquerque 3 4 5 2 3 -9
    Durham 9 8 7 9 9 8 -4
    Boise 3 4 6 2 8 9 -1
    Jacksonville 2 5 2 1 5 7 2 1 1 -3
    Lexington 8 9 12 3 4 10 11 -6
    Tulsa 8 2 9 5 6 11 8 4 2 9 -1
    San_Francisco 1 1 2 1 1 -8
    Washington -3

    Program:
    import java.io.File;
    import java.io.FileNotFoundException;
    import java.io.PrintStream;
    import java.util.Scanner;
    public class CFPInputOutput {
