Effective Java(TM) Programming Language GuidePage 197C H A P T E R5Substitutes for C ConstructsTHEJava programming language shares many similarities with the C programming language but several C constructs have been omitted. In most cases its obvious why a C construct was omitted and how to make do without it. This chaptersuggests replacements for several omitted C constructs whose replacements are notso obvious.The common thread that connects the items in this chapter is that all of theomitted constructs are dataoriented rather than objectoriented. The Java programming language provides a powerful type system and the suggested replacements take full advantage of that type system to deliver a higher qualityabstraction than the C constructs they replace.Even if you choose to skip this chapter its probably worth reading Item 21which discusses the typesafe enum pattern a replacement for Cs enumconstruct.This pattern is not widely known at the time of this writing and it has several advantages over the methods currently in common use.Item 19: Replace structures with classesThe Cstructconstruct was omitted from the Java programming language becausea class does everything a structure does and more. A structure merely groups multiple data fields into a single object; a class associates operations with the resultingobject and allows the data fields to be hidden from users of the object. In otherwords a class can encapsulate its data into an object that is accessed solely by itsmethods allowing the implementor the freedom to change the representation overtime (Item 12).Upon first exposure to the Java programming language some C programmersbelieve that classes are too heavyweight to replace structures under some circumPage 2CHAPTER 5 SUBSTITUTES FOR C CONSTRUCTS98stances but this is not the case. Degenerate classes consisting solely of data fieldsare loosely equivalent to C structures:// Degenerate classes like this should not be public!class Point {public float x;public f ...
