After unpacking the "apache-tomcat-6.0.24-src.tar.gz" file in /home/anurag folder. when I move to apache-tomcat-6.0.24-src/bin and try to start the server by running command:

try this...
import javax.swing.*;
class Demo
{
public static void main(String[] args)

int str;
String s;
int l,sum=0;
s=JOptionPane.s howInputDialog( " enter integer");
str=Integer.par seInt(s);
l=s.length();

1. Go to C:\WINDOWS\syst em32, copy cmd application file.
2. Place this into C:\Program Files\Java\jdk1 .6.0_06\bin\New _beg directory.
3. Create a shortcut to cmd application on the desktop.
When you double-click on that, you will be in C:\Program Files\Java\jdk1 .6.0_06\bin\New _beg directory.Leave a comment:

It means that some of the methods that you're using in the program is deprecated in the Java API you're using. Try to compile and run your program using old Java API, e.g. if you're using JDK1.5 then try your program on JDK1.2, or lower versions.Leave a comment:

String s=s1+s2;

Memory is allocated for an object with the new operator. And now question is, how this memory is deallocated? Unlike C\C++ where memory is deallocated using the delete operator. java handles memory deallocation by an automatic called, Garbage Collection.
when no reference to an object exists , then that object is considered to be no longer required, and hence becomes a suitable candidate for garbage collection.
Garbage collection...Leave a comment:
