The Scanner class of the java.util package gives you methods like nextInt(), nextByte(), nextFloat() etc. to read data from keyboard. To read an element of an array uses these methods in a for loop:Example Live Demoimport java.util.Arrays; import java.util.Scanner; public class ReadingWithScanner { public static void main(String args[]) { Scanner s = new Scanner(System.in); System.out.println("Enter the length of the array:"); int length = s.nextInt(); int [] myArray = new int[length]; System.out.println("Enter the elements of the array:"); for(int i=0; i
You need to use the transaction SE11. This transaction is used to create indexes on the tables.One main thing to keep in mind over here the way these indexes are moved to production. You need to use the transaction to create indexes in development environment. Once they are created, you need to transport them to the production environment.Once you have made the change, activate the table.
While writing an interface/class names you need to keep the following points in mind. First letter of the interface/class name should be capital and remaining letters should be small (mixed case). interface Sample Likewise, first letter of each word in the name should be capital an remaining letters should be small. interface MYInterface Keeping interface names simple and descriptive is suggestable. Better not to use acronyms while writing interface/class names. Example Live Demo interface MyInterface { void sample(); void demo(); } ... Read More
Yes, you can do what you are aspiring for. But it depends upon your actual requirement. Let’s say you need to execute the some custom application or program in SAP, then you can opt for any available connector which reads a file or else. This connector then later establishes a connection to the queue and then sends a message.Let’s say you cannot keep polling for files availability, and then you need to use the remote function call methodology. RFC has a SDK available and its online support is tremendous. You can use it too for sending a message. Read More
You made a small mistake but a mistake having a big impact. SSIS 2014 does not support VS 2012 in your case. Just switch to VS 2013, your problem will be resolved.
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 ...

You are absolutely correct. You cannot use anything other than DI to perform data manipulation.Because if you violate this, the warranty is void and SAP would stop any kind of support it.Coming to your point of using EF in your project, I will issue a simple warning to you just because a basic operation also results in updating many tables. In simple words, a lot of data manipulation happens. So in case you still stick to using EF, then you will need to take care of doing that on your own.
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
While you have a valid point that most of the SAP HANA projects are coupled with varied SAP landscape but there does exists a lot of projects which involve only native SAP HANA development.It entirely depends on your interests and knowledge base but sound understanding of the core concepts around data ware housing needs to be clear, if you are planning to build anything utilizing the base concepts.Presently, as per my understanding, clients prefer ABAP on HANA as they have one or other existing ABAP solutions. So, any enhancement using ABAP seems more sensible and appropriate.So I will suggest you ... Read More
This cannot be overridden or suppressed by a pseudo code of pragma. If you run your query with extended syntax check, you will find the message as well that this cannot be suppressed. The extended check can be done by going to PROGRAM => Check => Extended Syntax Check
