(Intro to Java)
explain the answers to the below questions using step-by-step explanation.
(language: Intellij-Java)
Part One: Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5).
Part2: Write a method which gets a value from the user and convert that value from Celsius to Fahrenheit:
- For Celsius to Fahrenheit conversion use: F = 9*C/5 + 32
- Print the result of the conversion
Part3: Create a method which takes an integer array input from the user and reverses the elements in the array. Print the reversed array.
- For example, the expected “reversed” result for an array [5,33,0,8,2] is [2,8,0,33,5]
- Don't use any inbuilt/existing array reverse method. Try to write the reversing logic

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…

One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming a calculation using the following formula: nextGuess = (lastGuess + n / lastGuess) / 2 When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, next-Guess becomes lastGuess and the approximation process continues.
