6.18 Lab: Flip a Coin Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0.

The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies.def exact_change(user_total)def SomeMethod(a,b): a= a+b b=b+a print(a,b,end=" ") return (a+b) def main(): x=10 y=20 print(SomeMethod(x,y)) main() x and y are called: ? a and b are called: ?7.24 LAB: Car value (classes) Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()).

So for example: “CaTs RuLe!” would be given back as “cAtS rUlE!” . Spaces and punctuation should be left in place. You can use the Character class static functions to test the case of each letter. You do not need to place any code in static methods (besides the main method), you do not need to worry about try/catch blocks, and you do not need to make the program run more than once. in java
