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]

You have a file Chocolate.java and you have a driver class named Driver.java. Fill in the correct visibility modifiers so that the comments in the main method are upheld.  public class Driver {     public static void main(String[] args) {         Chocolate t = new Chocolate();         // each of the lines below is run independently        System.out.println(t.numPieces); // compile error         System.out.println(t.getCost()); // compiles and runs        System.out.println(t.cost); // compiles and runs     } } —— in a separate file in a different package/directory ———  public class Chocolate {        1   int numPieces;       2   double cost;       3   double getCost() {        return cost;     }     /** no-argument constructor implemented **/ }    1  :[vis1]   2  :[vis2]   3  :[vis3]

You have a file Cat.java and you have a driver class named Driver.java. Fill in the correct visibility modifiers so that the comments in the main method are upheld.  public class Driver {     public static void main(String[] args) {         Cat t = new Cat();         // each of the lines below is run independently        System.out.println(t.age);    // compiles and runs        System.out.println(t.isKitten); // compiles and runs System.out.println(t.getIsKitten()); // compile error     } }  —— in a separate file in a different package/directory ———  public class Cat {        1   int age;       2   boolean isKitten;       3   boolean getIsKitten() {        return isKitten;     }     /** no-argument constructor implemented **/ }    1  :[vis1]   2  :[vis2]   3  :[vis3]

Complete the following code. Make sure to complete the code in such a way that doesn’t invalidate the comments and that no implicit conversions are taking place on assignments of primitive data types.  [import] public class Test {     public static void main(String[] args) {         int percent;         double price;         // create a keyboard Scanner         Scanner scanner = [init]         // get an integer value from the user         percent = [int]          // get a double value from the user         price = [double]           // compute sale         double sale = price * (percent/100.00);         // print sale to 1 decimal place    [print]     } }
