![]() ![]() The main difference with the scheme used in Java is the absence of a containing annotation, which the Kotlin compiler generates automatically with a predefined name. Java repeatable annotations are also supported from the Kotlin side. A programmer is always said to write clean codes, where naming has to be. This will make it repeatable both in Kotlin and Java. It will not only be easier to read and maintain, but it can help find bugs a lot faster. To make your annotation repeatable, mark its declaration with the meta-annotation. Just like in Java, Kotlin has repeatable annotations, which can be applied to a single code element multiple times. To avoid generating the TYPE_USE and TYPE_PARAMETER annotation targets, use the new compiler argument -Xno-new-java-annotation-targets. ![]() This is an issue for Android clients with API levels less than 26, which don't have these targets in the API. This is just like how the TYPE_PARAMETER Kotlin target maps to the .TYPE_PARAMETER Java target. If a Kotlin annotation has TYPE among its Kotlin targets, the annotation maps to .TYPE_USE in its list of Java annotation targets. The MyApplication.java file would declare the main method, along with the basic SpringBootApplication. ![]() RunWith Use to specify a runner object that the test case will be called from. The following are the basic and mostly used annotations. JUnit 3 started to compliment this new JDK something that worked perfectly. Ability to not generate JVM 1.8+ annotation targets We also cover some Spring Boot best practices. Java 5 has introduced us to the concept of Annotations. ![]()
