I am looking for the better way to do arrays, This is my way but I am not sure if it is suitable.

Code:
package arraylist;

import java.util.ArrayList;

/**

public class Arraylist {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
         
 

	  /*This is how elements should be added to the array list*/
	ArrayList<Integer> weeklyTemperatures = new ArrayList<Integer>();
		weeklyTemperatures.add(78);
		weeklyTemperatures.add(67);
		weeklyTemperatures.add(89);
		weeklyTemperatures.add(94);
		weeklyTemperatures.add(2, 111);
                System.out.println(weeklyTemperatures.get(0));
                
    }
    
}
