![]() JAR file containing the HelloWorldApp.class file inside the dist.Software programmers surely have their preferred tools when it comes to developing applications and among the most well-known and appreciated Integrated Development Environments (IDEs), NetBeans IDE is on one of the top spots. File bytecode HelloWorldApp.class after compilation is inside the build / classes / helloworldapp section. We can check the built files by opening the Files window and expanding the HelloWorldApp section (the name of the project). To build the program, select Run> Clean and Build Main Project or press the shortcut Shift + F11. Recompile the application and create a *.Delete all files that have been compiled and previously built. ![]() Using this Clean and Build command, the IDE will run the necessary code to perform the following tasks: Building and deploying applications:Īfter writing the source code, checking it, we can use the Clean and Build feature to build the program. Click the error icon to move to the line containing the code. The markings on the left will correspond to the lines of the code containing the error, and the right error symbol will indicate all the files with errors, including unseen errors. If an error occurs, they will be marked with a red arrow symbol on the left and right-aligned at the Source Editor section. When the system displays the message as above it means that the compilation process was successful To run the program, select Run> Run Main Project or press F6: This Project Properties can also adjust settings for: project libraries, packaging, building, running.
