Hi,
Can anyone please tell me the relationship between Portlet and Web Service? Any suggestion for Portlet development tutorial?

There is no any direct implementation in API.
U can do that using GregorianCalendar.

I suggest to convert both the object to Date object. Date class implements Comparable interface which has a method called compareTo(Object o). Using the method, one can compare two Date object.

1. int i=0;
2. i=i++;
3. System.out.println(i); //print out 0

i is initialized to 0 before it gets incremented to 1.

Nayan

class X {
public static void main(String[] args) {
int i = 0;
while (i++ < args.length) {
System.out.print(args[i]);
}
}
}

Here is the explanation:
Inside the while loop, the conditional part is i++ < args.length. i.e
i=i+1(but this is a postfix operator).So for the first execution of while loop, the value of i=0 but the value becomes 1 after that conditional part. Like this, whenever i value reaches to 5, after post fix operation, the value becomes 6 inside the while loop. if u try to get the value of args[6],compiler will throws ArrayIndexOutOfBoundException (Subclass of RuntimeException).
If you use while(++i<args.length), then the output will be BCDEF.

Normally, these are both the console, but as shown in the above example it doesn't have to be.

what do u mean by that? Do u meanit shouldn't behave like that?

CheckedException-> The exceptions which can be handled by the programmer. In some scenarios, programmer can anticipate the type of exceptions that can be thrown from the application. As for example, whenever we do file operation, we know that it might throw FileNotFoundException if it can't locate the particular file.
UncheckedException-> The exceptions which can't be handled by the programmer, those are Unchecked exceptions. All unchecked exceptions are subclass of RuntimeException. These exceptions are ususally hadled by JVM. Programmer don't have control over these exceptions, so JVM takes care of that.

String class and all the Wrapper classes override the equals method by default to check the contents of two objects. For other classes, u have to override equals() method explicitly.

Nice example, Arun
I forgot to mention example!!

In some applications, output is redirected to a file. In that scenario, System.err.println() is used to display the error messages in the console. If we use System.out.println(), then all the messages will be redirected to the specified file. This is done in order to prevent the error messages being displayed in the redirected file.

I mean, put the whole file in a String object. Now, u can search for the keyword using the indexOf() method of String class. That will give u the position of the keyword(u are looking for). Now, get the data whole data using the location and append that in u'r file. For that, u can use of substring(int,int) method.
Does this help u?

Hi,
Do u use package in u'r Java program? If u use package, then u have to set that in u'r CLASSPATH, or else set the CLASSPATH=.;

Interface is primarily the replacement of Multiple inheritance in Java.

Nayan

One more solution....
U can use the class called Timestamp which extends Date class. Date class has methods of comparing two objects.
Hope, this helps u.

Hi Angela,
I think, u can use String class methods to seek for specific words location. RandomAccessFile won't be helpful for that matter.
