Chapter 9, Problem 4FTE
Explanation of Solution
Given statements:
//Tokenize a string that is delimited
//with semicolons. The string has 3 tokens
String str = "one;two;three"; //Line 1
String tokens = str.split(";"); //Line 2
System.out.println(tokens); //Line 3
Error in the given statement:
Tokenizing string:
- It is a process of breaking down the string into the components called tokens.
- The string can be split using the split method which breaks the string using the delimiter for breaking it.
- The split method is used for the tokenizing the string.
Error #1:
The “tokens” variable must reference the array of tokens that is returned by the method “split ()” in “Line 2”. So the statement must be rewritten as:
String[] tokens = str...

Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Along with driver code
True or FalseWhen you call a string object’s Split method, the method divides the string into two substrings and returns them as an array of strings.

- Name format: You must use String object and not StringBuffer or StringBuilder. Many documents use a specific format for a person's name. Write a program that take one Line as an input. Example: Scanner input = new Scanner(System.in); System.out.println(“Enter firstName middleName lastName separated by at least one blank, It may have more than one blank separating firstName middleName lastName."); Input sample : Pat Silly Doe || Note these are separated by at least one blank. String line = input.nextLine() Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J. Please submit the .java source file and the sample run in a text file.

- Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter.
