(Financial application: compute the future investment value) Write a method that computes future investment value at a given interest rate for a specified number of years. The future investment is determined using the formula in
Use the following method header:
public static double futureinvestmentValue (
double investmentAmount, double monthlyinterestRate,int years)
For example, futureinvestmentValue(10000, 0.05/12 , 5) returns 12833 0 59.
Write a test program that prompts the user to enter the investment amount (e.g., 1,000) and the interest rate (e.g., 9%) and prints a table that displays future value for the years from 1 to 30, as shown below:

- Correct the following wrong statements. In Java, once a variable is declared in a method as local variable, it will be visible and could be used in any other method in the program.arrow_forward(Number of days in a year) Write a method that returns the number of days in a year using the following header: public static int numberOfDaysInAYear(int year)Write a test program that displays the number of days in year from 2000 to 2020.arrow_forwardCode in C# (OOP Concept) Do a program that does the following: Ask for a number from the user in the main method o Pass thenumber to a method call it "Multiplication”. In the Method Multiplication, multiply the number by a number enteredby the user (mention that the number should be positive). Send the result back to the main and print it from the mainModify the previous program if the user enters a negative second number in the method Multiplication, do not acceptthe number and ask the user to reenter it again. . Add another method call it also Multiplication Ask for a float numberfrom the main and send it to the new Multiplication. This method should also ask for another positive number fromthe user and multiply it by the float number. Design and implement a function called "multiply" in C++ that accepttwo numbers and returns either the arithmetic multiplication or repetition of a given string a specific number of timesdepending on the data types of the argument values.

- Using METHOD SAMPLE Problem: Create a method that will compute the value of PI, if pi is 3.14. Given formula is : value = pi x square of radius Solution: float area(int radius) final float pi = 3.14f; float val; val = pi * (float) (radius * radius); return(val); Direction: Analyze the given problem and create a java method.

- (language: Intellij-Java) Part One: Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5). Part2: Write a method which gets a value from the user and convert that value from Celsius to Fahrenheit: - For Celsius to Fahrenheit conversion use: F = 9*C/5 + 32 - Print the result of the conversion Part3: Create a method which takes an integer array input from the user and reverses the elements in the array. Print the reversed array. - For example, the expected “reversed” result for an array [5,33,0,8,2] is [2,8,0,33,5] - Don't use any inbuilt/existing array reverse method. Try to write the reversing logicarrow_forwardHere's the problem " (Math: approximate the square root) There are several techniques for implementingthe sqrt method in the Math class. One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming a calculation using the following formula: nextGuess = (lastGuess + n / lastGuess) / 2 When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, next-Guess becomes lastGuess and the approximation process continues. Implementthe following method that returns the square root of n.public static double sqrt(long n)" I have my java code here " import java.util.Scanner;public class Main2 {public static void main(String[]…arrow_forward(3) public static void test_b(int n) { if (n>0) test_b(n-2); System.out.println(n + " "); Consider the following method: What is printed by the call test_b(4)?

- Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.arrow_forwardProblem: Construct a program that simulates the major Bank Transactions: Deposit, Withdraw and Inquire. Your program should use methods for the 3 transactions and another method for the login transaction. Below is the initial structure of the your code: public class BankTransaction { static void DisplayMenu() { /*this method displays the menu of the transactions*/ } static void withdraw(float amount) { /*this method should deduct the amount withdrawn from the current balance*/ } static void deposit(float amount) { /*this method should add the amount deposited to the current balance*/ } static float inquire() { /*this method should return the current balance*/ } static boolean CorrectPinNUmber() { /*this method should ask user to input the pin number. returns TRUE if the pin number is valid*/ It } public static void main(String a[]) { } } Design your main program to test these methods. You can design your own user interface.arrow_forwardT/F 5) The following two methods will both compute the same thing when invoked with the same value of x.
