Problem specification
Given a text containing sentences, you need to implement
the methods of class String, apply it on your string and
evaluate your methods by String methods.
The methods that you are going to implement is
substring(int,int), replace(char, char), replaceAll(char, char),
compareto(string), length().
You need to define an array of character at first and run
above methods on them. Then transform the array of char to
a String and apply the same methods that have been
provided by Java. The result should be the same.
You need to enter the String and ask the user which method
she is going to run. Depending on the method that user
chooses, you are required to ask related info. For example if
user chose compareto(string) you need to ask which string
should be compared with the original one.
Error conditions
Think of different possibilities that make the program
incorrect.
Hints
The java API is there to help you.
To create a string from your character array use
String(char[] value) method from String class.
