Lab 8 - Strings
CSE 110 Principles of Programming with Java
Spring 2021
Due April 4th 2021, 11:59PM Arizona Time
1 Lab Objectives
The following objectives will be met at the end of this lab -
• Declare and define String objects
• Find the length of a String object
• Use various String functions
• Perform String manipulation
1.1 Lab Objectives
The source code file Lab8.java that you will create in this section, is what you will upload as your submission file to Canvas by
the due date for this lab. Please ensure that the source code runs on your machine and produces the co
ect output as required.
Overall Objective: For this lab, you will accept two Strings from the user and then perform the following
operations on them - find the length of the two Strings, determine if they are uppercase, lowercase or mixed
case Strings and finally you will check if the two user-input Strings are equal or not.
For this section, you will create a new project in your IDE called Lab8 and create a source file called Lab8.java inside that
project. The following requirements must be met to successfully complete this section -
Obj.1 [1 point] Within the main() function create an object of the Scanner class for user input.
Obj.2 [2 points] Within the main() function, create two String objects to hold the user input.
Obj.3 [2 points] Within the main() function, accept two Strings from the user using the Scanner object.
Obj.4 [2 points] Within the main() function, determine and display the length of the two user-input String objects.
Obj.5 [5 points] Within the main() function, determine if the user input Strings are alphanumeric or if they contain any
special characters in them. Display a message letting the user what type of Strings have been entered.
Obj.6 [(2+4) points] Define a static boolean function called compareStrings(String s1, String s2) that returns true
if the Strings s1and s2 are the same.
Obj.7 [2 points] Within the main()function, call the function compareStrings(...) to compare and display if the two use
input Strings are the same or not.
Note: You can use extra functions as you see fit. There is no limitation on how many functions you use to achieve the end
esult.
Once you are done editing your source code, make sure to save it (save often to prevent loss of data and work) and then
compile your source code. The next step is to follow the submission guidelines in Section 2 of this document and turn you
lab in.
