1 Write a Java program the displays the State bird and flower. You should use your IDE for this exercise. The program should prompt the user to enter a State and print both the State bird and flower. The user should be able to enter a State without worrying about case. (e.g. Users could enter Maryland, maryland, MARYLAND or any other possible combination of lower and upper case characters. States may also contain leading and trailing white spaces. Hint: Store the State information in a multi-dimensional array. The program should continue to prompt the user to enter a state until “None” is entered. You will need to do some research to find the State birds and flowers. Here is a sample run:
Enter a State or None to exit: Maryland
Bird: Baltimore Oriole
Flower: Black-eyed Susan
Enter a State or None to exit:
Delaware
Bird: Blue Hen Chicken
Flower: Peach Blossom Enter a State or None to exit:
None

Design a class named Clock. You should use your IDE for this exercise. The class contains private data fields for startTime and stopTime, a no argument constructor that initializes the startTime to the current time, a method named start() that resets the startTime to the given time, a stop() method that sets the endTime to the given time and a getElapsedTime() method that returns the elapsed time in seconds. Create a TestClock class to construct a Clock instance and return the elapsed time. Command line arguments should be used to send the start and end times. You should use the java.time classes. Here is sample run:
java TestClock 11:45:12 11:48:13 Elapsed time in seconds is: 181

Create your own simple Java application to generate X random Integer values between 0 and Y. Use command line arguments for entry of X and Y.
Demonstrate your code compiles and runs without issue using screen captures as appropriate.
Try other student’s code, adding additional functionality as appropriate.

Write a Java program the displays the US State capital and population.
The program should prompt the user to enter a State and print both the State Capital and Population.
The user should be able to enter a State without worrying about case. (e.g. Users could enter California, california, CALIFORNIA or any other possible combination of lower and upper case characters). States may also contain leading and trailing white spaces.
Hint: Store the State information in a multi-dimensional array.
The program should continue to prompt the user to enter a state until “None” is entered.

Create your own data file consisting of integer, double or String values.
Create your own unique Java application to read all data from the file echoing the data to standard output. After all data has been read, display how many data were read. For example, if 10 integers were read, the application should display all 10 integers and at the end of the output, print “10 data values were read”
Demonstrate your code compiles and runs without issue.
