Methods & String Assignment

You absolutely must know how to use the following string methods: length(), charAt(), substring(), indexOf(), as well as changing a String to a character array and vice versa.
There are some other very simple methods that you also need to know: toUpperCase(), toLowerCase(), trim().

Strings are very useful and important, so the more you know about handling and manipulating them the better.

This is an introductory program but some of the later programs are quite hard to do. Take time and work out the procedure that you think should work - probably before you start coding.

Program

Write a program that does the following. It should use methods and no global variables.

• gets a string from the user
• The string should be be changed to all lowercase (or uppercase) for ease of manipulation. (So you don't need to worry about a word being Big, big or BIG. It's all the same word.) It won't matter in the end what the case is.
• write a method that removes all articles: "a" and "the". Do not remove other words that contain these letters (like "other", "scythe")
• You also need to check for the sentence beginning or ending with an article
• write another method that changes the words "pick up" to "pickup" and also changes "climb up" to "climb"
• print out the string
• now remove the second word (this does not have to be in a method, it can be in main() if you want) and print the string out again.

If you have extra time, write another method that removes all punctuation (ie. anything that is NOT a letter, a number, or a space).

And also remove consecutive spaces.
