Java 8: More efficient way of comparing lists of different types?

Question

In a unit test, I want to verify that two lists contain the same elements. The list to test is build of a list of Person objects, where one field of type Stri

Answer 1

This is how I solved the equality of 2 lists of Person

public class Person {
  private String name;
  //constructor, setters & getters 
  @Override
  public boolean equals(Object o) {
    if(this == o) return true;
    if(o == null || getClass() != o.getClass()) return false
    Person p = (Person) o;
    return name.equals(p.name);
  }
  @Override
  public int hashCode() { return Objects.hash(name);}
}

// call this boolean method where (in a service for instance) you want to test the equality of 2 lists of Persons.
public boolean isListsEqual(List givenList, List dbList) {
  if(givenList == null && dbList == null) return true;
  if(!givenList.containsAll(dbList) || givenList.size() != dbList.size()) return false;
  return true;
}

// You can test it in a main method or where needed after initializing 2 lists    
boolean equalLists = this.isListsEqual(givenList, dbList);
if(equalLists) { System.out.println("Equal"); }
else {System.out.println("Not Equal");}   

I hope this can help someone in need.
