write a program that takes two double command line arguments representing the sides of a rectangle. The program should then call a void function that reports the area of the rectangle accurate to three decimal places.
Program71.java
Write a program that creates a 32-element array of random integers all from 1 to 100, inclusive. Then execute a custom method with the array as its only argument. The method should begin by using a loop to print the array elements in 4 rows and 8 columns, with all columns being five characters wide. Duplicates are okay. This same loop should determine how many integers in the array are odd numbers. After this loop ends, use this figure to declare a new array of integers named odds. Process the array again in the method, but this time with a foreach loop, and add the odd integers to the odds array. Return the odds array back to main. In main, report the size of the array and sort it ascending. Finally use a while loop to print the odd integers all on one line separated by spaces.
Program72.java
See Section 7.13 and watch the Command Line Arguments (2:08) video (video image below). Then, write a program that takes two double command line arguments representing the sides of a rectangle. The program should then call a void function that reports the area of the rectangle accurate to three decimal places.
