Part2:
Write a class that contains the following two methods:
/** Convert from feet to meters */
public static double footToMeter(double foot)
/** Convert from meters to feet */
public static double meterToFoot(double meter)
The formula for the conversion is:
meter = 0.305 * foot
foot = 3.279 * meter
Write a test program that invokes these methods to display the
following tables:
Feet

Financial Application:• Write a program that computes future investment value at a given interest rate for aspecified number of months and prints the report shown in the sample output.
• Given the annual interest rate, the interest amount earned each month is computedusing the formula:
Interest earned = investment amount * annual interest rate /1200 (=months * 100)
• Write a method, computeFutureValue, which receives the investment amount, annualinterest rate and number of months as parameters and does the following:
o Prints the interest amount earned each month and the new value of theinvestment (hint: use a loop).
o Returns the total interest amount earned after the number of months specified bythe user.
The main method will:o Ask the user for all input needed to call the computeFutureValue method.o Call computeFutureValueo Print the total interest amount earned by the investment at the end of thenumber of months entered by the user.

- Program4 - (from ch7) - Computer-Assisted Instruction (Project Name: AITeacher) - The use of computers in education is referred to as computer-assisted instruction (CAI). Write a program that will help an elementary-school student learn multiplication. Use a Random object to produce two positive one-digit integers. The program should then prompt the user with a question, such as: How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it is correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student gets it right. A separate method should be used to generate each new question. This method should be called once when the app begins execution and each time the user answers the question correctly.arrow_forwardT/F 5) The following two methods will both compute the same thing when invoked with the same value of x.
