Write a Java class called PyramidVolume that reads from the user 2 integers represent
area of the base (B) and the height of a pyramid (h).
Then calculates and prints the volume of this pyramid (rounded to 1 decimal place)
according to the following formula:
volume = (1/3) h B
Note:
If the user enters any non-positive value (i.e. less than or equal to zero), an error message
should be displayed and nothing should be calculated.

Functions With No Parameters but With Return Values Practice II
by CodeChum Admin
Create a function named askInput that asks the user an integer input if called. The function will return the string “Even” if the integer is even, and “Odd” if otherwise.
In the main function, call the askInput function and store the returned value in a variable then print it in a newline.
Input
1. One line containing an integer
Output
Enter·a·number:·10
Even
1. In a sample Java source code three variables ag1, age2 and age3 are declared as integers, where age3 stores the sum of age1 and age2. An object showAge is also defined in the code; write only a print statement to display the sum of age1 and age2 using the object
2. Write a simple program in Java to display the age of a father from the following statement: The sum of ages of two sons is 5 less than the age of their father
3. Write an executable source code in Java that receives two decimal numbers from a user and returns their average on a display screen

All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program. You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the number of monthly payments you’ll…arrow_forward
