使用ArrayList的removeRange方法

protected void removeRange(int fromIndex, int toIndex)

import java.util.ArrayList;

public class MyArrayList<E> extends ArrayList<E> {
    public void removeRange(int fromIndex, int toIndex) {
        super.removeRange(fromIndex, toIndex);
    }

    public static void main(String[] args) {
        MyArrayList<Integer> list = new MyArrayList<>();
        list.add(1);
        list.add(2);
        list.add(3);
        list.add(4);
        list.add(5);

        System.out.println("Before remove: " + list);
        list.removeRange(1, 4);
        System.out.println("After remove: " + list);
    }
}

Before remove: [1, 2, 3, 4, 5]
After remove: [1, 5]
