import java.util.ArrayList;

public class TemperaturesC {

public static void main(String[] args) {

	ArrayList<Integer> weeklyTemperatures = new ArrayList<Integer>();
	weeklyTemperatures.add(78);
	weeklyTemperatures.add(67);
	weeklyTemperatures.add(89);
	weeklyTemperatures.add(94);
	weeklyTemperatures.add(2, 111);

	for (int j = 0; j < weeklyTemperature.size(); j++) {
  
  System.out.println( weeklytemperature.get(j) );
  
}

}

}

You will have to make up your mind
weeklyTemperature
weeklyTemperatures
weeklytemperature
