Question

I have a method that returns a double. When I call this method and print its result, it prints out 10.3333333 for example. I would like the method to return a something like 10.3 instead.

The method is:

  public double getscore() { 
      int x=0;
      double x1=0;
      for (int i=0; i<3 ;i++) {
          x+=mark[i];
      }
      x1=x/3;
      return (x1);
 }

Answer 1

    double d = 1.234567;
    DecimalFormat df = new DecimalFormat("#.#");
    System.out.print(df.format(d));
