I was studying Annotations in that while executing the below problem.
this code i am executing in JDK 12.0.1 in windows 10.
class food{
public void eat(){
System.out.println("eat something");
}
}
class food1 extends food{
@Override
public void eat(){
System.out.println("done...........");
}
}
class test{
public static void main(String[] args)throws Exception{
food f=new food1();
f.eat();
}
}
I expected output-done but it is showing error
\\Error: A JNI error has occurred, please check your installation and try
\\again
