Java keyword list abstract continue for new switch assert default goto * package synchronized boolean do if private this break double implements protected throw byte else import public throws case enum instanceof return transient catch extends int short try char final interface static void class finally long strictfp volatile const * float native super while Keyword marked with an asterisk (*) are keywords that, although valid, are not used by programmers. This is the last chapter of the Java Keyword series. This is probably the keyword I have used the least. In my 20 year career as a software developer, I have used this keyword once, and that was to make some addition to legacy code. The keyword native is a method modifier . Basically, it is a keyword that can only be applied to methods. According to the Java Language Specification (JLS), A method that is native is implemented i...
When determining the relationship between object at design time, it is easy to succumb to the habit of using inheritance; simply because it is easy. In a language such as C++, it is even easier to do so because the language supports multiple inheritance. Figure 1 : the java.util. List Interface Assume that Java does not have a Stack (java.util.Stack) class and you need to create a custom stack (call it MyStack). You could do this in three different ways, but for the purposes of this paper I will discard the creation of the Stack class as shown in the image above. Therefore, assume that there are only two ways. The first way is to extend the ArrayList class. The second way is to include an ArrayList object as a data member. The first solution uses inheritance to solve the problem. Remember, inheritance establishes an “is-a” relationship between objects. Therefore, the relationship between MyStack...
