Question

Write a Java program that computes a business’s potential profits each year for 20 years using the following assumptions:

1. Gross profit in the first year is projected to be $20,000.
2. Expenses in the first year are expected to be $35,000.
3. Net profit or loss is gross profit minus expenses.
4. Gross profits are expected to increase 10% each year.
5. Expenses are expected to increase 4% each year.

Display the year, the gross profit, the expenses, and the net profit for each year. Use “printf” to make the output look uniform. Also display the year in which a net profit is first reported.

Answer 1

public class Main
{
   public static void main(String[] args)
   {
   //variable declaration and initialization
   float grossProfit = 20000;
   float expenses = 35000;
  
   //calculate net profit or loss
   float netProfitLoss = grossProfit - expenses;
   System.out.printf("\n\nYear 1:\nGross profit = %.2f\nExpenses = %.2f\nNet loss = %.2f", grossProfit, expenses, Math.abs(netProfitLoss));
   for(int i=1; i<20; i++)
   {
   //calculate gross profit
   grossProfit = grossProfit + grossProfit * 10 / 100;
  
   //calculate expenses
   expenses = expenses + expenses * 4 / 100;
  
   //calculate net profit or loss
   netProfitLoss = grossProfit - expenses;
  
   //display the result
   if(netProfitLoss<=0)
   {
   System.out.printf("\n\nYear %d:\nGross profit = %.2f\nExpenses = %.2f\nNet loss = %.2f", (i+1), grossProfit, expenses, Math.abs(netProfitLoss));
   }
   else
   {
   System.out.printf("\n\nYear %d:\nGross profit = %.2f\nExpenses = %.2f\nNet profit = %.2f", (i+1), grossProfit, expenses, Math.abs(netProfitLoss));
   }
   }
   }
}
