The substring() method is used to return a part (or substring) of the String used to invoke the method. The first argument represents the starting location (zero-based) of the substring. If the call has only one argument, the substring returned will include the characters to the end of the original String. If the call has two arguments, the substring returned will end with the character located in the nth position of the original String where n is the second argument. Unfortunately, the ending argument is not zero-based, so if the second argument is 7, the last character in the returned String will be in the original String s 7 position, which is index 6 (ouch). Let s look at some examples:

public String toLowerCase()
This method returns a String whose value is the String used to invoke the method, but with any uppercase characters converted to lowercase for example,
String x = "A New Moon"; System.out.println( x.toLowerCase() ); public String toString() // output is "a new moon"
This method returns the value of the String used to invoke the method. What Why would you need such a seemingly do nothing method All objects in Java must
Using the String Class (Exam Objective 8.2)
have a toString() method, which typically returns a String that in some meaningful way describes the object in question. In the case of a String object, what more meaningful way than the String s value For the sake of consistency, here s an example:
String x = "big surprise"; System.out.println( x.toString() ); public String toUpperCase() // output reader's exercise
This method returns a String whose value is the String used to invoke the method, but with any lowercase characters converted to uppercase for example,
String x = "A New Moon"; System.out.println( x.toUpperCase() ); public String trim() // output is "A NEW MOON"
This method returns a String whose value is the String used to invoke the method, but with any leading or trailing blank spaces removed for example,
String x = " hi "; // result is " hi // result is "hix" x"
System.out.println( x + "x" ); System.out.println( x.trim() + "x");
The StringBuffer Class
The StringBuffer class should be used when you have to make a lot of modifications to strings of characters. As we discussed in the previous section, String objects are immutable, so if you choose to do a lot of manipulations with String objects, you will end up with a lot of abandoned String objects in the String pool. On the other hand, objects of type StringBuffer can be modified over and over again without leaving behind a great effluence of discarded String objects.
A common use for StringBuffers is file I/O when large, ever-changing streams of input are being handled by the program. In these cases, large blocks of characters are handled as units, and StringBuffer objects are the ideal way to handle a block of data, pass it on, and then reuse the same memory to handle the next block of data.
