You can also create a copy of the existing clients between local and remote system IDs. Follow the below steps to create a copy of existing clients − Step 1 − To create a copy of a client in local SID, the transaction code is SCCL. Step 2 − Enter the following details − Select your desired profile, enter source client, and enter description. Step 3 − By default, the client copy is executed in a single process and you can distribute the workload on multiple processes to reduce time for copying. Step 4 − Copying a ... Read More
The answer is very naïve. If you have any quantity fields or currency fields, you require reference columns and reference table. You need to just add the reference field and table for any such columns in your table.
Passing Parameters by Value means calling a method with a parameter. Through this, the argument value is passed to the parameter. Example public class SwappingExample { public static void swapFunction(int a, int b) { int c = a+b; System.out.println("Sum of the given numbers is ::"+c); } public static void main(String[] args) { int a = 30; int b = 45; swapFunction(a, b); } } Output Sum of the given numbers is ::75
The File class provides exists() method this returns true if a file in the specified path exists else it returns false.ExampleLive Demoimport java.io.File; public class FileHandling { public static void main(String args[]) { File file = new File("samplefile"); if(file.exists()) { System.out.println("Given file existed"); } else { System.out.println("Given file does not existed"); } } }OutputGiven file does not existed
Java uses javac (compiler) to convert the java code to byte code (.class file). Then, JVM internally converts the byte code to system understandable code using the interpreter in addition to it JVM. Instead of executing a piece of code, again and again, JVM identifies them as “hot spots” and compiles them using Just in time compiler and, later reuses the same when required. Just in Time compiler is a compiler which is used by JVM internally to translate the hot spots in the byte code to machine understandable code. The main purpose of JIT compiler is to do heavy ...

You can use SUM if function as status is always 1 or 0.=IF(SUMIF(C:C,Q4,G:G)>=6,1,0)
As per dictionary, abstraction is the quality of dealing with ideas rather than events. For example, when you consider the case of e-mail, complex details such as what happens as soon as you send an e-mail, the protocol your e-mail server uses are hidden from the user. Therefore, to send an e-mail you just need to type the content, mention the address of the receiver, and click send. Abstraction is a process of hiding the implementation details from the user, only the functionality will be provided to the user. In other words, the user will have the information on what ...

You can make use of function code which is assigned to push button with “Exit” as function type and an event “AT SELECTION-SCREEN ON EXIT-COMMAND” to achieve this.A call is made to this event to validate the fields on the screen and you can implement all logic here.
Maven is a build tool which is based on the concept of a project object model (POM), Maven can manage a project's build, reporting, and documentation from a central piece of information. Using maven, we can build and manage any Java-based project. In case of multiple development teams environment, Maven can set-up the way to work as per standards in a very short time. As most of the project setups are simple and reusable, Maven makes a life of developer easy while creating reports, checks, build and testing automation setups. Maven provides developers with ways to manage the following: ... Read More
No, java.lang package is a default package in Java therefore, there is no need to import it explicitly. i.e. without importing you can access the classes of this package. If you observe the following example here we haven’t imported the lang package explicitly but, still we are able to calculate the square root of a number using the sqrt() method of the java.lang.Math class. Example Live Demo public class LangTest { public static void main(String args[]){ int num = 100; double result = ... Read More
