Mr. Agarwal invests certain sum at 5% per annum compound interest for three years. Write a program in Java to calculate: (a) the interest for the first year (b) the interest for the second year (c) the amount after three years. Take sum as an input from the user. Sample Input: Principal = ₹5000, Rate =10%, Time = 3 yrs Sample Output: Interest for the first year: ₹500 Interest for the second year: ₹550 Interest for the third year: ₹605

Here is a simple Java program that calculates the compound interest for each year and the total amount after three years:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("Enter the principal amount:");
        double principal = scanner.nextDouble();

        System.out.println("Enter the rate of interest:");
        double rate = scanner.nextDouble();

        double firstYearInterest = (principal * rate) / 100;
        System.out.println("Interest for the first year: ₹" + firstYearInterest);

        double secondYearPrincipal = principal + firstYearInterest;
        double secondYearInterest = (secondYearPrincipal * rate) / 100;
        System.out.println("Interest for the second year: ₹" + secondYearInterest);

        double thirdYearPrincipal = secondYearPrincipal + secondYearInterest;
        double thirdYearInterest = (thirdYearPrincipal * rate) / 100;
        System.out.println("Interest for the third year: ₹" + thirdYearInterest);

        double amountAfterThreeYears = thirdYearPrincipal + thirdYearInterest;
        System.out.println("Amount after three years: ₹" + amountAfterThreeYears);
    }
}

This program first takes the principal amount and the rate of interest as input from the user. It then calculates the interest for the first year by multiplying the principal with the rate and dividing by 100. The interest for the second year is calculated in a similar way, but the principal for the second year is the sum of the original principal and the first year's interest. The same process is repeated for the third year. Finally, the total amount after three years is calculated by adding the third year's principal and interest.
