    <p>I have a problem with understanding this code , My question is why the two threads does not interfere with each other during executing the statements in <code>run</code> method ?</p> <p>I mean that always a thead do all statements then come second thread to do statements.</p> <p>it is impossible that first thread do portion of statements then second thread do portion of statements then first thread continue its task .............</p> <p>note : I know that the two threads uses different <code>OutputStream</code> object</p> <p>Thread code here</p> <pre><code>class Printer extends Thread { private String ThreadName; public Printer(String name) { this.ThreadName=name; } public void run() { PrintStream out=new PrintStream(System.out); out.println(this.ThreadName+" : a"); out.println(this.ThreadName+" : b"); out.println(this.ThreadName+" : c"); out.println(this.ThreadName+" : d"); out.println(this.ThreadName+" : e"); out.println(this.ThreadName+" : f"); out.println(this.ThreadName+" : g"); out.println(this.ThreadName+" : h"); out.println(this.ThreadName+" : i"); out.println(this.ThreadName+" : j"); out.println(this.ThreadName+" : k"); } } </code></pre> <p>Entry Code:</p> <pre><code>class Main { public static void main(String[] args) { Thread t1 = new Printer("thread 1"); Thread t2 = new Printer("thread 2"); t1.start(); t2.start(); } } </code></pre> <p>try to replace <code>System.out</code> with <code>out</code> and compare the results then you will know exactly what am I asking for </p>

    3. COthe fact that they do not interfere when you run them does not imply that they do not interfere in general (e.g. run on another computer, under different circumstances etc.). When I run the code, the output of the first thread is typically 'paused' just before the newline when the output of the other thread is printed. And when repeatedly running the program, I get a different output each time.

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.
