You need to double check the PATH environment setting  C  Program Files Java jdk-13 you currently have there is not correct  Please make sure you have the bin subdirectory for the latest JDK version at the top of the PATH list   java exe executable is in C  Program Files Java jdk-13 bin directory  so that is what you need to have in PATH   Use this tool to quickly verify or edit the environment variables on Windows  It allows to reorder PATH entries  It will also highlight invalid paths in red   If you want your code to run on lower JDK versions as well  change the target bytecode version in the IDE  See this answer for the relevant screenshots   See also this answer for the Java class file versions  What happens is that you build the code with Java 13 and 13 language level bytecode  target  and try to run it with Java 8 which is the first  default  Java version according to the PATH variable configuration   The solution is to have Java 13 bin directory in PATH above or instead of Java 8  On Windows you may have C  Program Files  x86  Common Files Oracle Java javapath added to PATH automatically which points to Java 8 now     If it s the case  remove the highlighted part from PATH and then logout login or reboot for the changes to have effect  You need to Restart as administrator first to be able to edit the System variables  see the button on the top right of the system variables column

I also encountered similar problem which is asked here  The issue was that some applications come with their own JRE and sometimes the installed JDK appears at lower priority level in environment path  Now there are two options    Uninstall the other application which has their own JDK JRE  Sometimes it is not possible to remove the other application  which was my case  So I moved JDk installed by me to higher priority level in environment path      I also removed the path as suggested by  CrazyCoder

The problem is that you compiled the code with java 13  class file 57   and the java runtime is set to java 8  class file 52   Assuming you have the JRE 13 installed in your local system  you could change your runtime from 52 to 57  That you can do with the plugin Choose Runtime  To install it go to File Settings Plugins  Once installed go to Help Find Action  type  quot runtime quot  and select the jre 13 from the dropdown menu

[java] Has been compiled by a more recent version of the Java Runtime (class file version 57.0)
