Hi everyone,

im new on java..
currently reading ch2
there's this execrise at the end of ch2 which i dun quite get it
pg75 Q4

here's goes:
nSunVol = (long) (Math.PI * Math.pow ((nSunDia /2), 3) * 4/3);
nSunVol = (long) (4/3 * Math.PI * Math.pow ((nSunDia /2), 3));

it seen to me tat if i code it as L1 the ans is correct.
but when i coded it in L2 by switching the 4/3 to the front. It doesnt work.
Can anyone explain to me y?

thx

one can be u specified your variable as class variable
nothing wrong in this line
following program compile well

class SunVolume
{

  public static void main(String args[])
 {
       long nSunVol,nSunDia=17;
      nSunVol = (long) (Math.PI * Math.pow ((nSunDia /2), 3) * 4/3);
      System.out.println(nSunVol);
}
}
