a JNI error has occurred, please check your installation and try again and A java exception has ocurred error after exporting the program in eclipse

Question

After exporting the program, when I try to run the JAR file, the error occurs: a JNI error occurred, check your installation and try again followed by a java exception occurred. I have no idea how to solve this, I don't know if it's something about the code or the Java version I'll post the code here (the main code) so please help!

My java is: 8 281 as JDK

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
