```
public int hashCode(Object obj)
```
    Description copied from interface: Equivalence
    
    Returns a hash code value for the object passed. As an example, implementors can provide an alternative implementation for the hash code calculation for arrays. So, instead of relying on Object.hashCode(), call java.util.Arrays.hashCode().
    
    Specified by:
    
    hashCode in interface Equivalence<T>
    
    Parameters:
    
    obj - instance to calculate hash code for
    
    Returns:
    
    a hash code value for the object passed as parameter
  - equals
```
public boolean equals(T obj,
                      Object otherObj)
```
    Description copied from interface: Equivalence
    
    Indicates whether the objects passed are "equal to" each other. As an example, implementors can provide an alternative implementation for the equals for arrays. So, instead of relying on Object.equals(Object)}, call java.util.Arrays.equals()).
    
    Specified by:
    
    equals in interface Equivalence<T>
    
    Parameters:
    
    obj - to be compared with second parameter
    
    otherObj - to be compared with first parameter
    
    Returns:
    
    true if both objects are the same; false otherwise
  - toString
```
public String toString(Object obj)
```
    Description copied from interface: Equivalence
    
    Returns a string representation of the given object.
    
    Specified by:
    
    toString in interface Equivalence<T>
    
    Parameters:
    
    obj - whose string representation is to be returned
    
    Returns:
    
    a string representation of the passed object
  - isComparable
```
public boolean isComparable(Object obj)
```
    Description copied from interface: Equivalence
    
    Returns whether the given object is comparable. In other words, if given an instance of the object, a sensible comparison can be computed using Equivalence.compare(Object, Object) method.
    
    Specified by:
    
    isComparable in interface Equivalence<T>
    
    Parameters:
    
    obj - instance to check if it's comparable
    
    Returns:
    
    true if the object is comparable; false otherwise
  - compare
```
public int compare(T obj,
                   T otherObj)
```
    Description copied from interface: Equivalence
    
    Compares the two given objects for order. Returns a negative integer, zero, or a positive integer as the first object is less than, equal to, or greater than the second object.
    
    Specified by:
    
    compare in interface Equivalence<T>
    
    Parameters:
    
    obj - first object to be compared
    
    otherObj - second object to be compared
    
    Returns:
    
    a negative integer, zero, or a positive integer as the first object is less than, equal to, or greater than the second object
