What are the main differences between using thread pools and queues in thread management?

The hashCode() method in Java returns an integer value (int) that represents the hash code of the object. This code is used for quick search and comparison of objects, for example, in collections like HashMap or HashSet.

It is important that if two objects are equal according to equals(), their hashCode() must return the same value. However, different objects can have the same hash code (collisions).

Example of overriding hashCode():

@Override
public int hashCode() {
    return Objects.hash(field1, field2);
}

Here, Objects.hash computes the hash code based on the object's field values.
