问题 I'm putting the following at the end of my project gradle file: gradle.projectsEvaluated { tasks.withType(JavaCompile) { options.compilerArgs += ['-Xep:MissingOverride:ERROR', '-Xep:MissingCasesInEnumSwitch:ERROR',] } } However, in my code if I remove an @Override annotation somewhere or remove a switch statement, my Android project still builds. Shouldn't it fail with an error? 回答1: I googled your problem and found this post that described your problem and the solution looks like this:

问题 The following code String[] values = ... .... Map<String, Object> map = new HashMap<>(); for (int i = 0; i < values.length; i++) { map.put("X" + i, values[i]); } is converted by IntelliJ to: Map<String, Object> map = IntStream.range(0, values.length) .collect(Collectors.toMap( i -> "X" + i, i -> values[i], (a, b) -> b)); which can be shortened to Map<String, Object> map = IntStream.range(0, values.length) .collect(Collectors.toMap( i -> "X" + i, i -> values[i])); The 2 stream versions don't

问题 the problem is that I upgraded to Windows 10 and now I'm installing my tools to programming and now that I installed the JDK 7 of Java, when I try to use in the cmd the command: - "javac" The result of this is: "javac" is not recognized as an internal or external command... But I was edited the PATH with the correct link of jdk, because when I use "java", it is ok. Now, I tryed in the console with this command: PATH=%PATH%;"C:\Program Files\Java\jdk1.7.0_79\bin" And when I ejecute this

问题 I've been playing around with Java Annotation Processors, with great results. Now I would like to do the following, which as far as I can see is not possible. I have several Classes that implement the Builder Pattern. Say for instance new FooBuilder().doSomething("A").doSomethingElse("B").execute(); It is vital that the "chain" of method calls is terminated using an execute() method. Otherwise, the builder will basically do nothing. So I wanted to use JAP to verify the presence of an execute(

问题 Before, I had java 8. I recently installed java 11. I moved my path Java\jdk-11.0.7\bin to the top of my environment variables. When I do javac -version it gives me version 11. But when I do java -version , it gives me version 8. How do I correct this? Specifically, I want to run a jar file that was compiled using java 11. 回答1: Whenever you install JDK, it asks for the path of JRE as well. There is a possibility that you mentioned a different path for JRE than the JAVA_HOME or opted out the
