No. There is no need to switch to modules. There has never been a need to switch to modules. Java 9 and later releases support traditional JAR files on the traditional class path, via the concept of the unnamed module, and will likely do so until the heat death of the universe. Whether to start … Read more
You can use the JShell command to exit as: /exit Side note: Interestingly, with the use of command abbreviations for input shortcuts:- /ex (of course /exi) also, resolves into the same command.
Just add this <forceJavacCompilerUse>true</forceJavacCompilerUse> to your maven compiler build plugin in your POM and you’ll see all the javac errors! Source with more details
I had a similar case, and (as mentioned by @Holger in the comment) the module info in the message is simply misleading – this is an actual case of trying to cast something to something that doesn’t match it. In your case, ClientImpl simply is not a subtype of XigniteCurrenciesSoap.
The “old” way output a bunch of StringBuilder-oriented operations. Consider this program: public class Example { public static void main(String[] args) { String result = args[0] + “-” + args[1] + “-” + args[2]; System.out.println(result); } } If we compile that with JDK 8 or earlier and then use javap -c Example to see the … Read more
As others pointed out, the Map contract allows rejecting nulls… [S]ome implementations prohibit null keys and values […]. Attempting to insert an ineligible key or value throws an unchecked exception, typically NullPointerException or ClassCastException. … and the collection factories (not just on maps) make use of that. They disallow null keys and values. Attempts to … Read more
Add these dependencies into your pom/gradle: Gradle: compile(‘javax.xml.bind:jaxb-api:2.3.0’) compile(‘javax.activation:activation:1.1’) compile(‘org.glassfish.jaxb:jaxb-runtime:2.3.0’) Pom: <!– https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api –> <dependency> <groupId>javax.xml.bind</groupId> <artifactId>jaxb-api</artifactId> <version>2.3.0-b170201.1204</version> </dependency> <!– https://mvnrepository.com/artifact/javax.activation/activation –> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1</version> </dependency> <!– https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime –> <dependency> <groupId>org.glassfish.jaxb</groupId> <artifactId>jaxb-runtime</artifactId> <version>2.3.0-b170127.1453</version> </dependency>
With the help of this answer, I successfully solved the problem. We are going to apply a fix in sdkmanager. It is a shell script. It is located at $android_sdk/tools/bin, where $android_sdk is where you unzipped the Android SDK. Open sdkmanager in your favorite editor. Locate the line which sets the DEFAULT_JVM_OPTSvariable. In my copy, … Read more
Not exactly. JEP 247: Compile for Older Platform Versions defines this new command-line option, –release: We defined a new command-line option, –release, which automatically configures the compiler to produce class files that will link against an implementation of the given platform version. For the platforms predefined in javac, –release N is equivalent to -source N … Read more
This is part of JDK 9 in the form of or, which takes a Supplier<Optional<T>>. Your example would then be: return serviceA(args) .or(() -> serviceB(args)) .or(() -> serviceC(args)); For details see the Javadoc or this post I wrote.
