For the given code below, which lines are valid (will compile and run)? Assume each line is run independently.   public class Bottle {     private static boolean plastic;     private char letter;     public static int trash() {        return 0;     }     public boolean recycle() {        return true;     }     public static void main(String[] args) {         Bottle obj = new Bottle();         1 obj.recycle();        2 obj.trash();        3 Bottle.recycle();        4 Bottle.trash();                                  5 System.out.println(obj.letter);          6 System.out.println(obj.plastic);        7 System.out.println(Bottle.letter);        8 System.out.println(Bottle.plastic); } }   1  : [1]   2  : [2]   3  : [3]   4  : [4]   5  : [5]   6  : [6]   7  : [7]   8  : [8]
