The main difference is that the && is a logical operator, determining if something is equal at the logical level, whereas & determines the same from the bitwise level. If two strings are different, then they have different characters at some index that is a valid index for both strings, or their lengths are different, or both. It means that for a class to have a custom equality comparison, it must override the equals() method, providing its own implementation. 1 You can't compare with > & < because there might exist more than one variable in your object and Java won't know which variable you want to use for comparison.
