01 answer this Complete method printPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7: 42 seconds import java.util.Scanner; public class PopcornTimer {public static void printPopcornTime(int bagOunces) { /* Your solution goes here */ } public static void main (String [] args) {Scanner scnr = new Scanner(System.in);int userOunces; userOunces = scnr.nextInt();printPopcornTime(userOunces);}}}
Define a method printPrice() that takes one string parameter and one integer parameter and outputs as follows, ending with a newline. The method should not return any value. Ex: If the input is mango 2, then the output is: One mango costs 2 dollars. import java.util.Scanner; public class Price { /* Your code goes here */ public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String product; int productPrice; product = scnr.next(); productPrice = scnr.nextInt(); printPrice(product, productPrice); } }

U is upward, D is downward, L is left and R is right : Using the methods pickDir() and exractInt() as shown below, to write a simple automated game: how long does it take a robot to travel from a left line of a field to the right line? Assume field is 15 units apart (meters, kilometers, it doesn’t matter), and the robot starts on the left line. pickDir(): // return string with random direction and random distance (within maxDist) public static String pickDir (int maxDist) { Random r = new Random(); // random number generator // return direction + distance return ( "" + "LRUD".charAt( r.nextInt(4) ) + (r.nextInt(maxDist) + 1) ); } extractInt(): // returns integer from string, from pos p1 to p2: str = "D1" – extractInt(str,1,1); public static int extractInt (String str, int p1, int p2) { return ( Integer.parseInt( str.substring(p1, p2+1) ) ); } Write the main() method that keeps looping until the robot’s random left…
A pet shop wants to give a discount to its clients if they buy one or more pets and at least five other items. The discount is equal to 20 percent of the cost of the other items, but not the pets. Implement a method: public static void discount(double[] prices, boolean[] isPet, int nItems) The method receives information about a particular sale. For the ith item, prices[i] is the price before any discount, and isPet[i] is true if the item is a pet. Write a program that prompts a cashier to enter each price and then a Y for a pet or N for another item. Use a price of –1 as a sentinel. Save the inputs in an array. Call the method that you implemented, and display the discount.
