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...

Question 1 - Array Iterators
Like the JS on A2, there is no visual component to this question. The HTML really just needs to load the JavaScript, everything else
will output to the console. The JS file should the completion of the task, and all necessary testing, so that just loading the file will
complete the task with enough different inputs to ensure it works.
Even Numbers [3 marks]
Create a function that determines if a provided number is even. Define an array of numbers, then on the array use the appropriate
array iterator to determine if the array contains only even numbers using the function you defined. Output the results, and test with
several arrays.
Long Names [3 marks]
Define an array of names. Use an iterator to retrieve a new array containing only the names longer then 12 characters. Your iterator
should be passed an anonymous arrow function. Test with several different arrays
First Names [3 marks]
Define an array called fullNames that contains 7 javascript objects of...
