Avoid using breaks in loops or statments.
Ice Cream Truck
In this program, you will write a menu program for an ice cream truck.
Name your program IceCream.java
For this program, you will need to write 3 methods, as follows:
dispayTotal
Takes a double parameter for the total food price.
Takes another double parameter for the percent tip
calls the calculateTax method to add taxes to the price.
calls the calculateTip method to add the tip to the price.
Displays the price to two decimal places along with the message "With taxes and tip, your total comes to $<price>"
returns nothing
Note that you will need to watch the 16 videos before you can complete this method
calculateTax
Takes in a double parameter for the subtotal for the food.
Calculates the tax, assuming the tax rate is 9.25% in San Jose
adds the tax onto the the total price,
returns the update price
calculateTip
Takes in a double parameter for the current bill (price of food + tax).
Takes in…

- Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.arrow_forwardCreate a method that takes a value and indicate whether it is positive or negative by a return aBoolean value.Declared as: boolean isPositive (float a)arrow_forward2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For example 12 and 13 are relatively prime, but 12 and 14 are not. a. Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not. Sample Run 1: Enter Two positive integers X and Y: 12 13 12 and 13 are relatively prime Sample Run 2: Enter Two positive integers X and Y: 12 14 12 and 14 are not relatively primearrow_forward
