Difference between equality and identity in maths

identity: a variable holds the same instance as another variable.
equality: two distinct objects can be used interchangeably. They often have the same id.
E.g:
Integer a = new Integer(100);
Integer b = a;
a is identical to b.
Integer c = new Integer(100);
Integer d = new Integer(100);
c is equal but not identical to d.
Of course, two identical variables are always equal.
