If you want to get real fancy, you could make it into a combinator template grader, and give fewer marks if students submit code that generates warnings :-) But that's much harder. They could be question types like Java_program_allow_warnings, Java_class_allow_warnings etc. (PresenceServer.java is the class the above. Note: Recompile with -Xlint:unchecked for details. Once you've got it working the way you want, you could make it into a new question type (or several types, adding appropriate extra Java code for 'write-a-function', 'write-a-class', 'write-a-program' questions as appropriate). Note: PresenceServer.java uses unchecked or unsafe operations. That should, if I understand the Java compiler properly (which I don't) give you only genuine syntax errors rather than warnings. You could filter the stderr output to remove lines beginning with 'Note:' and print the rest to stdout. The relevant line here is "return_code = subprocess.call()": change that to a more-generic n (see documentation here) in which you capture the stdout and stderr output. To prevent that you'd have to change the script to capture the actual compiler output. But you'd still have the compiler warnings present in your got column, so the student would still fail the tests. class file after the compile phase and proceed to run the code if it's present, rather than abort if the compiler gives a non-zero return code. One option might be to check for the presence of a. Read Also: Solved java uses or overrides a deprecated api.

Now it's over to you to decide exactly how you want the compile-and-run process to work in the presence of compiler warnings. In this post, I will be sharing how to fix unchecked or unsafe operations. That will lock the question into Java only and the language-select dropdown will disappear. Under Advanced Customisation, set the Ace language to Java rather than a comma-separated list of options. Customise it, and pull out all the non-Java-relevant code. As it suggests, recompile with -Xlint:unchecked for details. Īs a starting point, to get a feel for what's possible, create a new write-a-program question of type 'multilanguage'. You are using collections without type specifiers. What are Java command line options to set to allow JVM to be. JsonMappingException: No suitable constructor found for type simple type, class : can not instantiate from JSON object. What causes javac to issue the 'uses unchecked or unsafe operations' warning.

However, your situation may be different, so. Sending Email in Android using JavaMail API without using the default/built-in app. I wonder whether warnings like this (another example is the use of deprecated code) could be captured another way, as the current approach prevents tests from running that could actually be run? It could be given in the preloaded code, but that would require some more teaching.Ĭurrently CodeRunner reports this as a syntax errorīut actually this does not prevent the student's code from compiling and it's not really a syntax error, just an unsafe practice. It also doesn't work for a single class if the student must add an import (as the annotation isn't legal before an import). It is possible to suppress these messages programmatically, and sometimes this could be hidden in a template so that students don't have to know about this feature: if you want a student to submit more than one class in the same answer box, altering the template no longer works. It used to be possible to suppress warnings like this at the compiler level by passing a flag like -Xlint:none or -nowarn, but as far as I can see this no longer works. Note: recompile with -xlint:unchecked for details" "Note: uses unchecked or unsafe operations.
What happens is that when students use raw types the Java compiler generates a message like this: I'm raising the same question here because I think it is a more general issue. workspace/platforms/android/src/org/crosswalk/engine/XWalkWebViewEngine.Another user posted a question here about this Note: Recompile with -Xlint:deprecation for details. workspace/platforms/android/gradlew: Command failed with exit code 1 Error output: SuppressWarnings('unchecked') //above the method definition. If you want to suppress such warning just use the below annotation. You can run your program without any problem. I also attempted to use cocoon.io but I kept getting a compile error noreply Add null checks to FhirIO.Search for when the search results are empty. Solved-Uses unchecked or unsafe operations, recompile with -Xlint-Java Search score:2 Those are just warnings buddy.
