The output prints the second array element,e. Just as printing it, you could use it in any other way where acharvalue is suitable. Furthermore, you can also iterate over all the array elements using aforeachloop as explained in our tutorialHow To Use Loops in Java. A loop is a struct...
.forEach(System.out::println);Copy If we run this, we get the output: cat dogCopy Let’s compare this with the equivalent code in plain Java using aforloop and abreakstatement, to help us see how it works: List<String> list = asList("cat","dog","elephant","fox","rabbit","duc...
Alpine Linux port for OpenJDK. A few of these improvements were ported to JDK 8, but in general, newer Java versions feel much better in containers and enable developers to use cloud resources more efficiently. Garbage collection changes
