   • Define Kotlin extension function in java code

     Top Answer

     Answered Jul 11, 2019 · 2 votes

     Actually, you can. Non out of box, but it is possible ;)

     Let's consider this example.

     First, create a class MyParent in Java

     public class MyParent {}-

     And, define extension method in this interface:

     interface MyParentExt { fun String.ext(importantParam: Int)}

     So, let MyParent implement this interface.

     public class MyParent implements MyParentExt {- @NonNull @Override public String ext(@NonNull String $receiver, int importantParam) { // do cool stuff return $receiver; } // For testing let's add other public method: public String ext(int importantParam) { return "Kotlin > Java"; }}

     So, let's check what we can do in childs:

     // Java child:public class MyJavaChild extends MyParent { MyJavaChild() { "Java xD".ext(0); // Invalid! There is no such a method! ext("Java xD", 0); // Valid call for extension function ext(0); // Just Valid ;) }}// Kotlin class:class MyGreatKotlinChild : MyParent() { init { "Kotlin is cool".ext(0) // Valid extension function! ext("Kotlin is cool", 0) // Invalid call. There is no method with such a signature! ext(0) // Valid. }}

     So, we can access our extension method in both, Java and Kotlin using lang-specified notation.

     As one of your requirements you wanted this method to be protected. Unfortunately, visibility of interface methods is always public. So, you still should be able to call this function on a member.

     But... Let's check how does it actually works ;)

     // Javapublic class Test { public static void main(String[] args) { MyChild child = new MyChild(); // Both methods are valid child.ext("Java...", 0); child.ext(0); }}// Kotlinfun main() { child.ext(0) // Normal function, valid call. child.ext("It actually works...", 0) // Hah, no way ;) // Just to be sure: "String".ext(0) // Nope, this ext method is visible for only class scope.}

     Also, your parent class just can extend ParentOfMyParent class where you would define your extension methods:

     // Kotlinabstract class ParentOfMyParent { protected abstract fun String.ext()}// Javapublic class Parent extends ParentOfMyParent { @Override protected void ext(@NotNull String $receiver) { }}// Kotlin-childclass Child : Parent() { init { "".ext() }}// Java-childpublic class ChildJava extends Parent { ChildJava() { ext(""); }}

     This way method has a wantned visibility.

     For the Run/Debug configuration that you have been using to Remote Debug, have you followed these steps :

     If so, can you post a snapshot of the Run Configuration ?

     What I have usually done with a Remote Debug run configuration is Add Source as Java Projects to the Source tab on the Run/Debug configuration. Thus to add a project called so, I would proceed as follows :

   • Java Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous tree type:

     Top Answer

     Answered Apr 08, 2014 · 1 votes

     Netbeans allows you to run the code even if certain classes are not compilable. During the application's runtime, if you access this class it would lead to this exception.

     To ensure you get the exact compilation error, you need to deselect 'Compile On Save' in the project options.

   • Byte code and Source code in Java?

     Top Answer

     Answered May 23, 2017 · 5 votes

     Student.java is the Java source code file, a text file

     Student.class is the bytecode compiled from it, a binary file

     Student.exe is a Windows executable (also binary, but not something you usually get from Java)

     Student is not a file at all, just an abstract concept (a Java class, whose full name would be something like com.vicheanak.myapp.Student).

     You may also encounter Student.jar which is an archive of all the class files and other resources that make up the application or library.

   What is Java source code?

   • The source code is the raw material that will be transformed into a machine-readable format. The transformation of Java source code into a machine-readable format is the responsibility of the Java compiler, commonly referred to as javac. This tool is more than just a translator; it is also a gatekeeper.

   How do I write a source code?

   • To write a source code, all you really need is a simple text editor - like the Notepad on Windows or TextEdit on Mac. This way, source code can be saved as plain text (e.g. in ASCII coding or with UTF-8 encoding) with the correct file name ending for the programming language.

   Where do I find Java source code?

   • The Java source code for all the API classes is shipped in the JDK installer in a file named src.zip. It's often just sitting in your install directory. Unzip it, and have a look. If it's not there, you may have chosen not to install it; reinstall the JDK and watch for the "source code" option, making sure to include it.

   Dec 22, 2009 · Java has gotten rid of the entire notion of a textual preprocessor (if you take Java as a "descendent" of C/C++). We can, however, get the best benefits of at least some of the C preprocessor's features in Java: constants and conditional compilation.
