Hey guys,

I am trying to sort a String Array by the length of it's elements. I found only this solution: Arrays.sort(strs, Comparator.comparing(String::length)). Is there a more 'elegant' way to do it (strs is the name of the Array)?

Dear community, I've installed OpenJDK 21. I have configured JAVA_HOME and JDK_HOME accordingly, setup the JDK Runtime under Project Settings (JavaSE-21, which correctly points to the Eclipse Adoptium's jdk 21 folder). The build.gradle file is configured to run with Java version 21 (see following config). I have no clue why, when I start the Gradle tasks via the Gradle integration tab, it uses the java.exe included in the redhat's extension (java v. 17). Running gradlew from the shell, it works correctly (i.e. .\gradlew.bat init)...

I want to learn Springboot and webflux, need best resources recommendation

As said in the title, i have some idea about basic java, and i tried reading "hands on reactive programming in spirng 5" but i was lost. Someone told me i could jump into springboot, rather than learn spring first. If someone could help me with how i should proceed and which resources to use, that would be great. Thanks!

Flow chart to Java.

Hello! I was given a flow chart with no instructions on how to turn it to code. It's meant to be super basic because all we have really learned are scanners, strings, while, if, those kinds of things. I have been working on this for almost two days and keep striking out. I have included a screenshot of what I have figured out to so far.
