Question

I have the below code put in Eclipse, and I cannot get Eclipse to let me run it as a Java application. I was able to do so on the computer on which I wrote it, but I’ve tried twice since on two different computers and neither has the option. I’ve tried to set a manual configuration to do it and I’ve tried Alt+Shift+X, but neither worked. I can run Java applications on all of these computers normally, just not this one for some reason.

import java.util.Scanner;

public class Donor {

public String name;
public int age;
public double donation;

    Donor() {

    //Initialized to these values for debugging
    name = "NoName";
    age = 0;
    donation = 0;

    }

    Donor(String nameinit, int ageinit, double donationinit) {

    name = nameinit;
    age = ageinit;
    donation = donationinit;

    }

    public String toString() {

    String str = "";

    str += String.format("%s-30%i-6$%d-20", name, age, donation);

    return str;

    }

    public static void main(String[] args) {

    Scanner input = new Scanner(System.in);
    String nameinit = null;
    int ageinit = -1;
    double donationinit = -1;
    String outp = null;

    System.out.print("Enter the donor's name: ");
    nameinit = input.nextLine();

    System.out.print("Enter the donor's age: ");
    ageinit = input.nextInt();

    System.out.print("Enter the donation amount: ");
    donationinit = input.nextDouble();

    Donor d = new Donor(nameinit, ageinit, donationinit);
    outp = d.toString();

    System.out.printf("%s30 %s6 %s10", "Name", "Age", "Donation");
    System.out.print("\n" + outp);

    input.close();

    }

}

Have you clicked with the right button and choose “run as” option, Java Application? It should work just fine in any environment.
