When 4 is connected to the string "2 + 2" with a plus sign, the integer 4 is converted to the string "4" and the result is the string "2 + 2 = 4". However "2 + 2 = " + 2 + 2 is interpreted by Java to mean ("2 + 2 = " + 2) + 2 The first integer 2 is changed to the string "2" because it is being combined with the string "2 + 2". The result is the string "2 + 2 = 2". The last integer 2 is combined with the string "2 + 2 = 2". So, the last 2 is converted to the string "2". So the final result is "2 + 2 = 2" + "2" which is "2 + 2 = 22".
There is another string class, called StringBuffer, that has methods for altering its string object. We will not discuss the class StringBuffer in this text, but a table explaining many of the methods of the class StringBuffer is included in Appendix 4. Although there is no method that allows you to change the value of a String object, such as "Hello", you can still write programs that change the value of a String variable, which is probably all you want anyway. To perform the change, you simply use an assignment statement, as in the following example: String name = "Soprano"; name = "Anthony " + name; The assignment statement in the second line changes the value of the name variable so that the string it names changes from "Soprano" to "Anthony Soprano".
1 Screen Output Let me tell the world. println and present some material on formatting numeric output. As part of that material, we give a brief introduction to packages and import statements. Packages are Java libraries of classes. Import statements make classes from a package available to your program. out. println for screen output. out is an object that is part of the Java language, and println is a method invoked by that object. It may seem strange to spell an object name with a dot in it, but that need not concern us for now.
