Compile time errors are syntactical errors in the code which hinders it from being compiled. Example public class Test{ public static void main(String args[]){ System.out.println("Hello") } } Output C:\Sample>Javac Test.java Test.java:3: error: ';' expected System.out.println("Hello") An exception (or exceptional event) is a problem that arises during the execution of a program. When an Exception occurs the normal flow of the program is disrupted and the program/Application terminates abnormally, which is not recommended, therefore, these exceptions are to be handled. Example ... Read More
For SAP ABAP tables, you can enter up to maximum 16 characters. There is a limit of up to 30 characters on use of ABAP Variables, Classes and Method.When you run SE11 you can press F1 and it will show you maximum permitted limit on SAP ABAP Table name.It is not possible to extend this limit as for this you need to make changes in Kernel.
Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on. Thus when you write a piece of Java code in a particular platform and generated an executable code .class file. You can execute/run this class file on any system the only condition is that the target system should have JVM (JRE) installed in it. In Short, If you have a ... Read More
Not necessarily catch, a try must be followed by either catch or finally block. Example import java.io.File; public class Test{ public static void main(String args[]){ System.out.println("Hello"); try{ File file = new File("data"); } } } Output C:\Sample>Javac Test.java Test.java:5: error: 'try' without 'catch', 'finally' or resource declarations try{ ^ 1 error
A checked exception is an exception that occurs at the time of compilation, these are also called as compile time exceptions. These exceptions cannot simply be ignored at the time of compilation; the programmer should take care of (handle) these exceptions. if you use FileReader class in your program to read data from a file, if the file specified in its constructor doesn't exist, then a FileNotFoundException occurs, and the compiler prompts the programmer to handle the exception. Example import java.io.File; import java.io.FileReader; public class FilenotFound_Demo { public static void main(String args[]) { ... Read More
You need to set up a workflow engine and then customize event generation. Next is to write down a Java service to connect to SAP system using Java Connector and then register a RFC server. For this, you have to follow steps:Navigate to Transaction SM59 -> Expand TCP/IP connections directory and click on Create (F8).In the RFC destination field, enter the name of the RFC destination system. Next is to set the connection type to T (Start an external program through TCP/IP).Next is to provide a Function Module handler that can be called using tRFC from SAP system -> Next ... Read More

A java archive file is a file format/ archiving tool which contains all the components of an executable Java application. All the predefined libraries are available in this format. To include any of these (other than rt.jar) in to your project you need to set the class path for this particular JAR file. You can create a JAR file using the command line options or using any IDE’s. Creating a Jar file You can create a Jar file using the jar command as shown below. jar cf jar-file input-file(s) Let us consider an example, create a Sample Java ... Read More
A native method in Java is a method whose implementation is written in other languages such as c and c++. The ‘native’ keyword is used before a method to indicate that it is implemented in other language.
Yes, this is feasible. You can create simple transformation for XML in ABAP. You can also use cl_proxy_xml_transform to transform data between XML and ABAP. Let us say that you have created ABAP proxy using T-Code: SPROXY or it is generated via WebService generation utility, you can use utility class “cl_proxy_xml_transform” to convert data of the ABAP to XML format or also from XML → ABAP.
