} 433 Strings as objects The previous two sections of this chapter have concentrated on the basic data types and control structures of Java To conclude the chapter we are returning to strings There are a number of reasons behind this First, strings in Java are regarded as objects and we feel that before reading the next chapter it would be useful for you to see more messages being sent to objects and, also, since many of you will be familiar with strings within other programming languages it would be easy for you to understand the main object concepts that you need to program in Java Second, strings, while being regarded as objects in Java, have some properties of basic data types; these properties have been designed to appeal to C programmers who may have used strings in their programs in a non-object-oriented way Before proceeding it is worth reminding you of an item of vocabulary which will be used within this section A message is something that is sent to an object A message consists of a name and some arguments with the possibility of there being zero arguments When a message is sent to an object a variety of things could occur: first, the state of the object could be changed; second, the state of the object could be changed and a value returned from the message; third, the state of the object could remain unchanged and a value be returned Messages will correspond to the methods which are associated with the class which describes the receiver object When a message is sent to a destination object its class is discovered and the code corresponding to the message executed In Java there are two types of sequences of characters These are String and StringBuffer Objects described by the former are constants which cannot be changed, while objects described by the latter can be modified Normally Java code involves strings being converted into StringBuffers, modified and then reconverted into strings There are a number of ways of creating Strings and StringBuffers The first is to declare them using the normal declaration facility that you have seen previously For example, the declaration: String filename, rootDirectory; StringBuffer userName; declares two strings called filename and rootDirectory and a StringBuffer called userName These can be initialized by means of an assignment For example: userName = "James Davis"; sets the contents of userName to be the string "James Davis" This is very straightforward but hides a subtle point that we made in the first paragraph: in Java strings are regarded as objects, but there are facilities within Java for strings which are not object-oriented, but which have been included to smooth the path of programmers who are used to other languages (most notably C) when they program in Java If strings were pure objects in Java, then assignments such as the above would be disallowed The only way to communicate properly with a real object is via a message, so if strings were pure objects the way of setting the value of a string would be to write an expression such as: newUsersetStringValue("James Davis"); which sets a string value within the object newUser There are other examples of this compromise within Java For example, when you want to join together (concatenate) two strings and set a StringBuffer variable equal to the result of this operation, you would use the + operator For example, the code: StringBuffer pcFile = userId + "" + extension; concatenates the string in userId with the single character string "" and the string in extension The + operator carries out this concatenation and returns with the string which has been so.

operators, common collection APIs on the SystemLinqEnumerable class, to perform collection manipulation In the introduction to standard query operators, we spent a few pages detailing deferred execution and how developers should take care to avoid unintentionally reexecuting an expression via a subtle call that enumerates over the collection contents The deferred execution and resultant implicit execution of standard query operators is a significant quality, especially when the query execution is expensive Programmers should treat the query object as the query object, not the results, and expect the query to execute fully even if it executed already The query object doesn t know that the results will be the same as they were during a previous execution Listing 1425 appeared within an Advanced Topic section because of the complexity of calling multiple standard query operators one after the other Although requirements for similar execution may be common, it is not necessary to rely on standard query operators directly C# 30 includes query expressions, a SQL-like syntax for manipulating collections in a way that is frequently easier to code and read, as I ll show in the next chapter

14 showed a query using standard query operators for GroupJoin(), SelectMany(), and Distinct(), in addition to the creation of two anonymous types The result was a statement that spanned multiple lines and was fairly complex to comprehend, certainly a lot more complex than statements typically written in C# 20, even though it appears fully compatible with C# 20 syntax The introduction of standard query operators facilitated scenarios where such complex statements were desirable even though the resultant code may be complex and hard to read In addition, the queries which standard query operators implemented were functionally very similar to queries generally implemented in SQL

Depending on the frequency and time to execute, fixed statements have the potential to cause fragmentation in the heap because the garbage collector cannot compact fixed objects To reduce this problem, the best practice is to pin blocks early in the execution and to pin fewer large blocks rather than many small blocks NET 20 reduces the NET Framework problem as well, due to some additional fragmentation-aware code

The culmination of these two factors resulted in the C# language designers adding a new syntax to C# 30: query expressions With query expressions, many standard query operator statements are transformed into more readable code, code that looks very much like SQL In this chapter, I introduce the new syntax of query expressions and use this syntax to explain how to express many of the queries from the preceding chapter
