Java while loop predict the future tuition

Question

We would like to use while loop to predict the future tuition.

Suppose that the tuition for a university is $10,000 this year.

Tuition increases 7% every year.

In how many years will the tuition be doubled? 

public class Main {
  public static void main(String[] args) {
    double tuition = 10000; // Year 0
    int year = 0;
    //your code here

    System.out.println("Tuition will be doubled in " + year + " years");
    System.out.printf("Tuition will be $%.2f in %1d years", tuition, year);
  }/*from  ww w .ja v a  2s . c om*/
}




public class Main {
  public static void main(String[] args) {
    double tuition = 10000; // Year 0
    int year = 0;
    while (tuition < 20000) {// loop
      tuition = tuition * 1.07;// next year's tuition
      year++;
    }

    System.out.println("Tuition will be doubled in " + year + " years");
    System.out.printf("Tuition will be $%.2f in %1d years", tuition, year);
  }
}
