		// a for loop is used to execute the SAME STATEMENT multiple times.

		
		// a for loop usually starts at zero
		
		
		// but it can start anywhere
		
		
		// it has three parts
		
		
		// and it can go up by more than one
		
		
		// or even down by more than one.
		

		// compound interest means that you make a certain amount of money
		// and then your reinvest what you earned, combined with the principal. 
		// for example:
		/*
		double interestRate = 0.025; // 2.5 % interest rate
		double principal = 10000.0; // investment is 10 thousand dollars
		double firstYearInterestEarned = principal * interestRate; // you make the principal times the interest rate on the first year.
		
		System.out.println("First year: " + firstYearInterestEarned);
		
		double secondYearInterestEarned = (principal + firstYearInterestEarned) * interestRate;
		
		System.out.println("First year: " + secondYearInterestEarned);
