L05 - Using Arrays

1. Create a new class named UsingArrays.
2. Using the lecture slides as a guide, declare and initialize an array of four integers that contains the values 3, 7, 13, and 18.
3. Using a for loop, display each of the four array values and the square of that value.

Sample Dialog

3 squared is 9
7 squared is 49
13 squared is 169
18 squared is 324

4. Add a for loop and display each of the four array values. Also, if the value is less than 10, display the message less than 10. If the value is greater than 10 but less than 15, display greater than 10 and less than 15. If the value is greater than 10, display greater than 15.

Sample Dialog

3 is less than 10
7 is less than 10
13 is greater than 10 and less than 15
18 is greater than 15

5. Write a program called ArrayTest that will do the following actions (complete each action before moving on to the next one):
   • Create an array in the main method that contains the following integer values:
     • 34
     • 2
     • 14
     • 34
     • 58
     • 4
   • Print out all of the array values using a for loop
   • Find and print the array element with the maximum value
   • Find and print the average value of the elements in the array
   • Copy three elements from this array, starting at the second element, into a new array of size 3
