if / else if inside getter/setter Java -

i started education software engineering learning basics of java... have create simple text-based airport game , ran little trouble.

i tried google , sof search function , found many "solutions" however; none seem fix problem. forgive me "noob" qeustion :p

in game have several airports generates random amount of passengers each round, minimum of 100 , maximum of 999. used following code... works , doesnt give me errors still random results below 100. doing wrong? said tried many different ways seems neglect if / if else conditions...

int paxgenerator;  public int getpaxgenerator() {     return this.paxgenerator = (int) (math.random() * 1000);  }  public void setpaxgenerator(int paxgenerator) {      if (paxgenerator<100) {         this.paxgenerator = 100;     } else if (paxgenerator > 999) {         this.paxgenerator = 999;     }  } 

edit:

return this.paxgenerator = (int) (math.random() * 900) + 100; indeed fix problem, thx @user43219 however, sake of learning; can give me example of how should correctly implement if else statement? because want create 12 new objects, have generate different random number. if place random code outside getter/setters gives me same number everytime... , if else statement isnt allowed outside getter/setters... bear in mind im beginner things arent obvious me :p thx in advance!

you not calling setter. line:

return this.paxgenerator = (int) (math.random() * 1000); 

does not implicitly call setpaxgenerator() - bypasses setter , sets property value directly.
