I uninstalled Eclipse IDE due to this issue.
Then I tried to run java program in my Linux mint Terminal.
So I started with a small code
public class Myth
public static void main(Stringargs)
System.out.println("Hii There");
and run it by giving commands javac Myth.java
and java Myth but insted of giving output it gives the following error
Error: A JNI error has occurred, please check your installation and try again

This
java.lang.UnsupportedClassVersionError
means, that some of the libraries in your project are using diferrent version of java , and set accordingly in path.
Quick things to resolve this:
$>which java
output->location of current java (eg. /usr/bin/java)
java --version
output->1.7.0 or 1.8.0
if this is the case , try switching version, for this do the following:
export JAVA_HOME=<path to diff java version sdk>
export PATH=$JAVA_HOME/bin:$PATH
This allows new path to come in front of old path, also for eclipse specific errors, take a look at eclipse cache in home directory(.eclipse folder in your project). You may safely delete this directory along ith .project files if any and recompile.
Hope this helps!!
Edit: Offset=6 means your current version for java(JDK) is 1.6. Try switching it to later versions. Also check that you are using Jdk path and not jre path

java -v, would also do it, there should be no spaces. If it is then your current java path is something like (/usr/java/jre1.x.y/) instead it should be (usr/java/jdk/1.x.y)

change it to /usr/java/jdk1.8.0_171 . If you dont have a jdk installed get it from oracle site by accepting icense agreement, its free. oracle.com/technetwork/java/javase/downloads/… see java jdk 1.8 u171, and download jdk
