    <p>So I am creating a random code that's not necessarily pertinent to anything at this level, but I'm more testing a few ideas. So for some reason my code will work randomly, but for most of the time it's throwing out a random negative number usually in the vicinity of -413796084. I don't know why it's doing this and I am trying to keep the numbers in the vicinity of 0 - 50. I thought I had done it right but obviously I haven't. Also I am relatively new at Java, if that helps explain any mistakes I made.</p> <pre><code>import java.util.Scanner; import java.util.Random; class damagecalc { public static void main(String args[]){ Scanner input = new Scanner(System.in); Random randamage = new Random(); int totaldmg; System.out.println("Will you (a) attack, (s) defend, (d) skip your turn, (f) magic, (i) use an item?"); String dmgString = input.next(); char dmgChar = dmgString.charAt(0); if(dmgChar == 'a'){ for(int finaldmg=50;finaldmg&lt;=50;finaldmg++){ totaldmg = randamage.nextInt(10); } totaldmg = randamage.nextInt(); if(totaldmg &gt;= 50){ System.out.println("You have defeated the monster!"); }else{ System.out.println("Damage Dealt:" + totaldmg); } } } } </code></pre> <p>EDIT------------------------------------------------</p> <p>So I changed my code and fixed some things and now it's just spitting out 0 every time. Maybe now it will be a little easier to figure out. But I definitely need help.</p> <p>This is the new code:</p> <pre><code>import java.util.Scanner; import java.util.Random; class damagecalc { public static void main(String args[]){ Scanner input = new Scanner(System.in); Random randamage = new Random(); int totaldmg; System.out.println("Will you (a) attack, (s) defend, (d) skip your turn, (f) magic, (i) use an item?"); String dmgString = input.next(); char dmgChar = dmgString.charAt(0); if(dmgChar == 'a'){ for(int finaldmg=1;finaldmg&lt;=50;finaldmg++){ } totaldmg = randamage.nextInt(1); if(totaldmg &gt;= 50){ System.out.println("You have defeated the monster!"); }else{ System.out.println("Damage Dealt:" + totaldmg); } } } } </code></pre>

    2. COit's spitting out 0 because you have randamage.nextInt(1) with the 1 being non-inclusive. You're telling it to generate a random number between 0 and 0.

    3. COyou need to not have any of these: totaldmg = randamage.nextInt(); if you look at the code before you changed it, you have totaldmg = randamage.nextInt(10) and then you follow it up immediately with totaldmg = randamage.nextInt(); this would overwrite your correct number with the extremely large +/- numbers

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.
