Oh, this error is similar to trying to play a brand new video game on an old gaming system. It basically means that you’re trying to run a program compiled with a higher version of Java (version 15 in this case) on an older version of Java Runtime Environment (JRE). To fix this, you’ll need to upgrade your JRE to match or exceed the version the program was compiled on.
hey, this error typically pops up when you’re using a java version that is not compatible with your current system. the number “61” is indicating the java version. version 61 equates to java 17. so, probably you’re compiling with a lower java version but running with java 17. you could resolve this issue by making sure your java versions match in your environment. hope this helps!
