I am using Notepad++ for java problems (Please type the code in here and show me the output)

6.7 Financial application compate the future investment value) Wnie 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 Programming Exercise 2.21. Use the following method header public static double futureInvestmentvalueC double investmentAmount, double monthlyInterestRate, int years) For example, futureInvestmentValueCI0000, 0.05/12 returns 12833.59. Write a test program that prompts the user to enter the investment amount (eg 1000 and the interest rale (e g 9%) and prints a lable that displays future value for the years from 1 lo 30, as shown below: The amount invested: 1000 Annual interest rate: 9 Years Future Value 1093.80 1196.41 13467.25 14730.57

1)

MinimumOf3Nos.java

import java.util.Scanner;

public class MinimumOf3Nos {

   public static void main(String[] args) {
       //Declaring variable
       int minimum;
      
       //Scanner object is used to get the inputs entered by the user
       Scanner sc=new Scanner(System.in);
      
       //creating an integer array of size 3
       int[] nos=new int[3];
      
       /* getting the 3 numbers entered by
       * the user and populating them into an array
       */
       for(int i=0;i<3;i++)
       {
           //getting the number entered by the user
           System.out.print("Enter the number "+(i+1)+":");
           nos[i]=sc.nextInt();
       }
       //calling the method by passing the array as input
       minimum=min(nos);
      
       //displaying the minimum of 3 nos
       System.out.println("The minimum of 3 numbers is :"+minimum);

   }

   //This method find the minimum number among 3 numbers
   private static int min(int[] nos) {
       int min=nos[0];
       for(int i=0;i<nos.length;i++)
       {
           if(min>nos[i])
               min=nos[i];
       }
       return min;
   }

}

output:

Enter the number 1:45
Enter the number 2:12
Enter the number 3:99
The minimum of 3 numbers is :12

               {
               //calculating the investment value for every year
               futInvestmentValue = (investment_amount )* Math.pow(1 + (interest_rate/1200),i*12);
              
               //Displaying the investment value
               System.out.printf("%d %.2f",i,futInvestmentValue);
               System.out.println(" ");
               }

   }
