To compare the contents of two objects. The equality, "=", will simply tell you whether two objects are in the same memory location; it doesn't tell you whether their contents are actually the same. To compare the contents, there is an equals() method which tells you whether the contents are actually equal; there is also a compareTo() which can also tell you which of two objects is "greater". Since objects can be quite complex, the programmer may have to overwrite the (often useless) default behavior of these methods.
