hi friends,
How to read XML file into two dimensional array using java. Am new to this concept. Please suggest me any ideas and suggest any websites and examples regarding this question.
I have a big XML which contains around 300 elements. I need to modify 2 or 3 elements in this xml using Java. I don't want to go for conventional marshalling and unmarshalling as it involves the parsing of the whole XML. How is XPath/XSLT manipulation? I know that I can easily read the data but i need to modify the same and put in back in the same XML. The primary concern here is performance. Kindly advise

From what time I've spent with threads in Java, I've found these two ways to write threads.
public class ThreadA implements Runnable {
public void run() {
//Code
}
}
//with a "new Thread(threadA).start()" call
public class ThreadB extends Thread {
public ThreadB() {
super("ThreadB");
}
public void run() {
//Code
}
}
//with a "threadB.start()" call
Is there any significant difference in these two blocks of code?
