Chapter 7, Problem 5FTE
Explanation of Solution
Given code:
// String array creation
String[] words = { "Hello", "Goodbye" } ;//Line 1
// Convert the array value to uppercase
System.out.println(words.toUpperCase());//Line 2
Errors in the given code:
The error is present in the Line 2,
- In the statement to convert string to uppercase characters, the keyword “words” refers to the array name.
- But, to convert string array case to uppercase character, subscript of the array should be used...

these are directions and examples
myChoice( items )
This function accepts a list of items as input and creates a function that returns a randomly-chosen item. After choosing a random item, that same item will be always be returned, regardless of the functions input, with one exception. If the first input is the string 'rechoose', then a new random item will be chosen and therafter returned. this is KEYYYY!!
Examples
