implements interface extends ArrayList class

Question

I created an interface:

public interface Random<E>{
    // methods signatures
}

I know it is unusual to do so but I need to make a class extending the ArrayList class and implements this interface, so I write some code likes this:

public class RandomTest<E> implements Random<E> extends ArrayList<E>{
   // a lot of code
   // overriding methods

    public static void main(String[] args){
    RandomTest<Integer> list = new RandomTest<Integer>();
}

But it can't compile. Just keep showing -

"Syntax error on token "extends", , expected."

I am confused.

You are coding in java, the syntax is

Class A extends B implements C,D,E.....

you have changed the orders of extends implements....

replace

public class RandomTest<E> implements Random<E> extends ArrayList<E>{

for

class RandomTest<E> extends ArrayList<E> implements ....
