如何获取默认EquivalenceLibrary？

import java.util.Objects;

public class MyClass {
    private int value;

    // ...

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        MyClass other = (MyClass) obj;
        return value == other.value;
    }

    // ...
}

class MyClass:
    def __init__(self, value):
        self.value = value

    def __eq__(self, other):
        if isinstance(other, MyClass):
            return self.value == other.value
        return False

public class MyClass
{
    private int value;

    // ...

    public override bool Equals(object obj)
    {
        if (obj == null || GetType() != obj.GetType())
        {
            return false;
        }
        MyClass other = (MyClass)obj;
        return value == other.value;
    }

    // ...
}
