I am learning Threads in Java online and I am a beginner, I am facing difficulty in understanding some concept. Can anyone help me? Link I am learning from:<a href="http://www.codeproject.com/Articles/616109/Java-Thread-Tutorial" rel="nofollow">http://www.codeproject.com/Articles/616109/Java-Thread-Tutorial</a> Problem: <pre><code>public class Core { public static void main(String[] args) { Runnable r0,r1;//pointers to a thread method r0=new FirstIteration("Danial"); //init Runnable, and pass arg to thread 1 SecondIteration si=new SecondIteration(); si.setArg("Pedram");// pass arg to thread 2 r1=si; //<~~~ What is Happening here?? Thread t0,t1; t0=new Thread(r0); t1=new Thread(r1); t0.start(); t1.start(); System.out.print("Threads started with args, nothing more!\n"); } } </code></pre> EDIT: Code of FirstIteration and SceondIteration <pre><code>class FirstIteration implements Runnable{ public FirstIteration(String arg){ //input arg for this class, but in fact input arg for this thread. this.arg=arg; } private String arg; @Override public void run() { for(int i=0;i<20;i++){ System.out.print("Hello from 1st. thread, my name is "+ arg+"\n");//using the passed(arg) value } } } class SecondIteration implements Runnable{ public void setArg(String arg){//pass arg either by constructors or methods. this.arg=arg; } String arg; @Override public void run() { for(int i=0;i<20;i++){ System.out.print("2)my arg is="+arg+", "+i+"\n"); } } } </code></pre>

Guidance

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.
