SPECIFICATIONS:

• Class Name: StringLab02.java
• These if-else statements should be contained in a separate method that is called by the main method.
• If/Else-Statements: Use if and/or if/else-statements in the program.
• Run Once: Note that the sample output shows many different outcomes bymany different program-executions. Only one menu item (with appropriate user-defined input parameters) will be performed per program-execution.
• Default: Include a default message ("Not a valid number!") if the user chooses an invalid menu-option.

NOTES:

• Caution: Part 1: All of the sample output shown is from using the input String "this is a test", so the sample output will show 14 and 13 as the length and maximum index of the String, respectively. However, those numbers will change based on other input Strings used by Mimir to automatically test the program. If the String had been "Java is Life", then the numbers for length and maximum index would be 12 and 11, respectively. Therefore, do not hard-code results into a menu-option.
• Scanner: Programmers will likely experience a problem using the Scanner object after reading in alternating primitive data (such as an int) and a String object. Refer to 10:50 - 19:05 in the video that can be referenced from the "Chapter 4.4 - Scanner" webpage in Mimir's "Lesson" tab, the Scanner section of the Relevant API (Pro-Tip), and/or Section 4.4 in the textbook (Quirky Behavior) for a remedy. Judiciously call the nextLine() method of the Scanner object to remove the new line character (' '), when appropriate.
• Caution: Part 2: The nextLine() method of a Scanner object is used to "clear the buffer" of the carriage return that may have been left by a preceding nextInt() or nextDouble() method of the Scanner object. This is sometimes a necessary practice. However, do not call the nextLine() method of the Scanner objectunless the program will subsequently (absolutely for sure) call another method of the Scanner object to read from the input buffer in Mimir!
  • Note: In a real-IDE, calling the nextLine() method of the Scanner object will not cause a problem, regardless of the existence of data in the input buffer (provided by the user via the keyboard). However, Mimir is using a simulated-IDE that will experience a run-time error when the nextLine() method of the Scanner object is called without data in the input buffer.
• For example, if the last method call to a Scanner object for a particular run (execution) of a program is a nextLine(), then a run-time error will occur!
• Fabricate Tests: Since many of the test cases are hidden, the impetus on the student is to thorough vet code! Do not simply rely on the visible test cases (especially with the "equals" and "compare-to" operations.
• Test Often: Instead of writing the whole program (and debugging a gazillion syntax/logic mistakes), submit the program for testing in Mimir after the code forone menu-option is coded.
• String:Refer to the video in the "Chapter 4.3 - The String Class" webpage in Mimir's "Lesson" tab, the relevant API, the Java API for String, and/or Section 4.3 in the textbook for more information regarding the String class (and in particular, the methods of the String class)
• If/Else: Recall that an if-else structure will always execute exactly one result.
• Sample Output: The plethora of sample-output is provided in order to demonstrate several possible outcomes

STRING	ACTION	SAMPLE CODE	OUTPUT
	New line	System.out.print("a b");	a b
\"	Quotation mark	System.out.print("a and \"b\".");	a and "b".
