  1. POWondering about classes in arrays?
    text
    copied!<p>I have a script with the following code:</p> <pre><code> import java.io.IOException; import java.util.ArrayList; import java.util.Collections; import java.util.List; import java.util.Random; public class app { public static int p; public static int b=0; public static int i; public static int add; public static List&lt;Integer&gt; a = new ArrayList&lt;Integer&gt;(); public static List&lt;Node&gt; c = new ArrayList&lt;Node&gt;(); public static void main(String[] args){ Random rand = new Random(); for( i = 0;i&lt;=10;i++){ int random = getRandom(); if(random!=0){ a.add(random); }else if(random == 0){ } } Collections.sort(a); System.out.println(a); for(int z = 1;z&lt;a.size();z++){ Node n = new Node(); Node.pos=a.get(z); System.out.println("Node pos set to "+a.get(z)); c.add(n); System.out.println("Node at " + n.pos); } System.out.println("class array length " + c.size()); System.out.println("Node at index " + 0 +" has a pos of " + c.get(0).pos); } public static int getRandom(){ Random randd = new Random(); int randomnum = randd.nextInt(10); if(!a.contains(randomnum)){ return randomnum; }else if(a.contains(randomnum)){ } return 0; } } </code></pre> <p>Now what I'm trying to accomplish with this, is I want the Node <code>n</code> that's created to be added to an array, which holds all the nodes and their positions. But it seems like once I create another node, all the nodes before it change their pos to that one.</p> <p>For example, I can try <code>c.get(0).pos</code> and it will return the same number as the one at 9, or however big the array is. How do I make every node that's added to the array keep its values? What's the problem?</p>
