    <p>Total novice here trying to learn myself java with tools online. Right now Im clearly doing something wrong as I cant figure out how to get a separate class file to return a random int. The random code is fine, its just I don't know how to actually get it to return properly! Probably seems like java 101 to a lot of you but im lost. lol</p> <p>I want them in seperate class files as an excersize in how to not put everything in one file. This workd fine if I just put it in one class, but thats not what I want to practice here. Thanks for any help!</p> <p>Class file 1:</p> <pre><code>package whatsthis; import java.util.Random; import java.util.Scanner; public class Noidea{ private static Scanner user_input; public static void main(String[] args) { System.out.println("Git is awesome"); Scanner user_input = new Scanner(System.in); randnum rn = new randnum(); System.out.println("RANDOM NUM: " +rn); System.out.println("What is your name?"); String first_name; first_name = user_input.next(); System.out.println("Hello, "+first_name); int health = 100; while( health&gt;0 ) { //System.out.println(rndNum); //System.out.println(rndNum); System.out.println(health); System.out.println("Attack? Y/N"); String attack; attack = user_input.next(); if (attack.equals("Y")){ System.out.println("KILL!"); System.out.println("You've done " + rn + " damage!"); //health = health - rn; System.out.println(health); } else { System.out.println("cower.."); } } } } </code></pre> <p>Class file 2:</p> <pre><code>package whatsthis; import java.util.Random; public class randnum { public int randnum() { int Low = 10; //Used for lowened number in random int High = 15; //Used for highend number in random Random rndGen = new Random(); //Declare a new 'random' object int rn = rndGen.nextInt(High-Low) + Low; //Proper random between two numbers (high and low) return rn; } } </code></pre> <p>Instead of the number im looking for, it returns <strong>whatsthis.randnum@2d09b23b</strong> Why ios this and how do I fix it? Sorry again if this is painfully simple. </p>

    1. COI would change public int randnum() to public static int getrand() and then call it using int rn = randnum.getrand(). Don't use the same name for a class and a method within that class, unless the method is a constructor.

    2. COHello Paul, good question you got there. Very specific. I just want to comment on your 'randnum' class. When you are creating a class, every first letter of the class should be in Uppercase. In your case, it should be RandNum. I hope this help in your learning. Good luck!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
