我如何把它放在一个 for 循环中

Question

I would like to put the following to a for loop. How do I do this since we haven't studied arrays yet. My instructor would like me to put the quarters 1-4 to a for loop.

quarter = 1;
interest = principal * quarterlyRate; // item 5
finalAmount = principal + interest;
System.out.printf("%6s%8d%16.2f%30.2f%n", year, quarter, interest, finalAmount);```

Answer 1

Maybe this is what you want:

# looping here
for (int i=0; i<4; i++) {
   interest = principal * quarterlyRate; // item 5
   finalAmount = principal + interest;
   System.out.printf("%6s%8d%16.2f%30.2f%n", year, i, interest, finalAmount);```
}
