Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

Question

Create a Java Code that satisfies the Coffee Machine requirements. You should define at least 4 methods.
checkResources ()-check if the resources are sufficient
a. When the user chooses a drink, the program should check if there are enough resources to make
that drink.
b.
E.g., if Latte requires 200ml water but there is only 100ml left in the machine. It should not
continue to make the drink but print: "Sorry there is not enough water."
c. The same should happen if another resource is depleted, e.g., milk or coffee.
processCoins ()
a. If there are sufficient resources to make the drink selected, then the program should prompt the
user to insert coins.
b.
Remember that quarters = $0.25, dimes = $0.10, nickels = $0.05, pennies = $0.01
c. Calculate the monetary value of the coins inserted
isSuccessful () - to check if the transaction is successful
a. Check that the user has inserted enough money to purchase the drink they selected.
E.g., Latte cost $2.50, but they only inserted $0.52 then after counting the coins the program
should say "Sorry that's not enough money. Money refunded.".
b. If the user has inserted too much money, the machine should offer change.
makeCoffee ()
If the transaction is successful and there are enough resources to make the drink the user
selected, then the ingredients to make the drink should be deducted from the coffee
machine resources.

IN JAVA - Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. End with a newline. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.

Write, Compile and Execute a Java program that prompts the user to enter a point (x, y) and checks whether the point is within the circle centered at (0, 0) with radius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, as shown in Figure below. (Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10. The formula for computing the distance is the square root of ((x₂-x₁)² + (x2 - y1)²). Test your program to cover all cases.) y-axis A (4,5) (0, 0) (9,9) Two sample runs are shown below. x-axis y-axis A (2,2) (0,0) Enter a point with two coordinates: 2 2 Enter Point (2.0, 2.0) is in the rectangle Enter a point with two coordinates: 6 4 Enter Point (6.0, 4.0) is not in the rectangle (6,4) x-axis
