java - Number of player objects more than 30 -


lets have array list of players , want players above age of 30. players have usual attributes name , age , getname , getage methods. i'm new java here appreciated. thanks.

for(player p: players){ if(p.getage() > 30){ system.out.println(p.getname()); }}

here possible solution you. assumption: have class player , can read players , add in allplayers arraylist.

import java.util.*;  public class game {     //holds list of players.     arraylist<player> allplayers = new arraylist<player>();     //holds list of players older 30 years.     arraylist<player> olderthan30 = new arraylist<player>();      public game()     {         //read players list , fill in above arraylist players have.         //for example, allplayers = getallplayers(); can use io methods read external files.         //get players older 30 years of age calling method get30olderplayers().         olderthan30 = get30olderplayers();     }      private arraylist<player> get30olderplayers()     {         //an arraylist save player list return.         arraylist<player> olderthan30 = new arraylist<player>();          //loops through players 1 one.         (player p : allplayers)         {             //if player's age more 30....             if(p.getage() > 30)             {                 //...add arraylist olderthan30.                 olderthan30.add(p);             }         }         //at end return arraylist holds players older 30.         return olderthan30;     } }

good luck.
