I am trying to check if a gas pump is free for use && full of gas, and then I am trying to make that pump the pump to be used by the cars in a queue.
Thread carThreads[]=new Thread[TOTAL_CARS]; try { Pump pump1 = new Pump(); pump1.setName("pump1"); pump1.setFuelAmount(2000); pump1.setState(0); Pump pump2 = new Pump(); pump2.setName("pump2"); pump2.setFuelAmount(2500); pump2.setState(0); Pump chosenPump = new Pump(); if( pump1.getState()==0 && pump1.getFuelAmount()<0 ){ chosenPump = pump1; System.out.println("Pump1 is free and has a fuel amount of: "+ (pump1.getFuelAmount()) ); } else if ( pump2.getState()==0 && pump2.getFuelAmount()<0 ){ chosenPump = pump2; System.out.println("Pump2 is free and has a fuel amount of: "+ (pump2.getFuelAmount()) ); } //else{ // System.out.println("Must wait for the tanker. It should be here soon"); //} Random r = new Random(); Car car; for(int i = 0; i<TOTAL_CARS; i++){ car = new Car(i, chosenPump); System.out.println("car"+ car.getID() +" was created"); (carThreads[i] = new Thread(car)).start(); Thread.currentThread().sleep(r.nextInt(10000)); line.enqueue(car); chosenPump.usePump( (Car)line.getfirst(), chosenPump, line ); System.out.println("this is the new line size for gas: "+ line.size()); }//end for }//end try catch (Exception e){ }}//end of main
