It is not about the sequence. Consider these as two different programs.
My question is if I am passing the Runnable job to class A (Thread), still it is not executing it class B.

If I dont override run in class A , both line will print B.?

public class TestMe { public static void main(String[] args) { new A(new B()).start(); new Thread(new B()).start(); } } class A extends Thread{ public A(Runnable runnable){ super(runnable); } @Override public void run() { System.out.println( "A" ); } } class B implements Runnable{ @Override public void run() { System.out.println( "B" ); } }

Why above main method the first call print "A" and second is printing "B", although I am passing same job to both the thread?

Hi Bear,
Sorry about the misinterpretation of the question by me as my eyes skipped the part
<%
//This is where I want to use the value which is in the mobNo variable
%>
I thought he would be using the input value on the same page but not inside the jsp tags.

Thanks

Hi,
you can use a hidden variable on the page and once the user entered value you can set the value of this hidden variable on the same jsp page.
eg. document.getElementById('variableid').value = mobNo;

Thanks

Hi All,

Can anybody explain me the the code.

class VLA2 implements Comparator<VLA2> { private int dishSize; public static void main(String... s) { VLA2[] va = { new VLA2(40), new VLA2(200), new VLA2(60) }; Arrays.sort(va, va[0]); for (int i = 0; i < va.length; i++) { System.out.println(va[i].dishSize); } int index = Arrays.binarySearch(va, new VLA2(40), va[0]); System.out.println(index); index = Arrays.binarySearch(va, new VLA2(80), va[0]); System.out.println(index); } @Override public int compare(VLA2 a, VLA2 b) { return b.dishSize = a.dishSize; } public VLA2(int d) { dishSize = d; } }

Thanks

Hi

for that you must go for the further reading on Java introspection and reflection.
Have a look at the java.beans.Introspector class.

Thanks

Hi,

Look for the concept of type casting.
For your eg. you can call getVar() as follows.

Class myClass = Class.forName("myclass"); myclass myobj = (myclass) myClass.newInstance(); myobj.i = 54; myobj.getVar();


Thanks

Hi Wouter Oet,

Thanks for reminding me the rule. Onward I will follow it.

Thanks

Hi,

Please check this post.

Thanks

Hi,

Try this.

Edit: removed complete solution.

Thanks

Hi,

please check this link

Hi,

Integer.parseInt(args[0]);

This line will throw the ArrayIndexOfBound exception if you are not passing any parameter to main or if the interger greater than months.length.

Thanks

Hi,

Please suggest the right way of using the constructor!!I m not just getting as to hw it works!!

I/m not clear about your doubt.What are you trying to say?

1.How to use the constructor
2.How to write your own exception
3.How to throw an exception from try block.
4.How throw works in try catch block

Thanks

Hi,

What is the error?
Are you passing any non integer param to main?

Thanks

Hi,

Is it possible to throw an exception in try block

Its possible.
import java.io.FileNotFoundException; public class FirstException { FirstException(String msg) { msg = "this is bound to execute"; System.out.println(msg); } public static void main(String[] args) throws Exception { try { // Suppose here you are looking for any resource for eg.File // If program is unable to find file throw new FileNotFoundException(); } catch (FileNotFoundException e) { throw new Exception("File not found"); } catch (Exception e) { System.out.println(e.getMessage()); } finally { // This block will get get executed whether exception occures or // not. System.out.println("i will get printed"); } } }
