While choosing a package name you need to keep the following points in mind. The name of the package should be in small letters. It is suggested to start the name of the package with the top level domain level followed by sub domains, ex: com.example.tutorialspoint. Example You can declare a package as in. package com.mypackage.tutorialspoint; Public class Sample { Public static void main(String args[]) { System.out.println("Welcome to Tutorialspoint"); } } Executing a package You need to compile the file with packages using –d ...

No, we cannot override a final method in Java. The final modifier for finalizing the implementations of classes, methods, and variables. We can declare a method as final, once you declare a method final it cannot be overridden. So, you cannot modify a final method from a sub class. The main intention of making a method final would be that the content of the method should not be changed by any outsider. Example class Demo{ public final void demoMethod(){ System.out.println("Hello"); } } public class Sample extends Demo{ ... Read More
I faced a similar issue earlier but it was because of a bug in JAVA security package (refer link for more details)http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7044060I just got updated myself to latest OpenJDK7 and it solved my issue. I think you can try the same and check if it helps.
If you don’t want to create a custom table then you can for creating a data model with the help of reuse method. You can then save this newly created data model in staging MDG. Other option that you have is Z-table. You can create a Z-table to persist the data.Hope this helps!
You are correct as XSA supports the custom error pages but classic does not support custom error messages.In case you need to do in any way, then what you can try out is you need to parse all requests through a load balancer or a proxy and then show custom error message. And it is not a easy and maintainable approach.
Yes, this and super are keywords in Java. Where ‘this’ is used as a reference of the current object and, ‘super’ is used as a reference to the superclass object.
The parameter that you are using seems to be a import type and it will require an associated type in order to be of any use.You can define the table parameters for this. You can find them within the tables tab. Once you have defined them then you can use them for either export or import.Hope it works for you!
No, main is not a keyword in Java.
No, null is not a keyword. Though they seem like keywords null, true and, false are considered as literals in Java.
Since the size of an array is fixed you cannot add elements to it dynamically. But, if you still want to do it then, Convert the array to ArrayList object.Add the required element to the array list.Convert the Array list to array.Exampleimport java.util.ArrayList; import java.util.Arrays; import java.util.Scanner; public class AddingItemsDynamically { public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.println("Enter the size of the array :: "); int size = sc.nextInt(); String myArray[] = new String[size]; System.out.println("Enter elements of the array ...
