    Default JAVA Programmer Beginner


    I'm new to JAVA Programming and I need help. I'm using Eclipse as my IDE and I wrote a program:

    package org.babynamecomparison.java;

    import java.util.Scanner;

    public class BabyNameComparison {
    public static void manin(String[] args){
    Scanner userInputScanner = new Scanner(System.in);
    System.out.print("Enter 1st FirstName");
    String name1 = userInputScanner.nextLine();
    System.out.print("Enter 2nd First Name");
    String name2 = userInputScanner.nextLine();
    System.out.print("Enter 3rd First Name");
    String name3 = userInputScanner.nextLine();

    System.out.println(name1 + "" + name2);
    System.out.println(name1 + "" + name3);
    System.out.println(name2 + "" + name1);
    System.out.println(name2 + "" + name3);
    System.out.println(name2 + "" + name1);
    System.out.println(name3 + "" + name2);

    When I try to run it, it says "The selection cannot be launched, and there are no recent launches."
    I do get a warning that says, "Resource leak: 'userInputScanner' is never closed". What am I doing wrong?

    You can ignore the 'resource leak' warning, or you can silence it by "closing"
    the Scanner object with the method close() after your input instance of Scanner.
