The import java.util.Collections cannot be resolved

Question

package Collection_1;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;


public class ArrayListMethods {

    public static void main(String[] args) 
    {
        
        List<Integer> intList = new ArrayList<Integer>();
        intList.add(9);
        intList.add(0);
        Collections.sort(intList);
            
        }       

}

This code is giving the error The import java.util.Collections cannot be resolved while importing import java.util.Collections . I'm using sort method from Collections class. I'm using eclipse IDE for writing the code. If anyone has any idea please try to answer.
