Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
java
Exercise 1:
Write a
Ask a user to enter two integer numbers
Finds the square root of each number
Finds the minimum
Finds the maximum.
Exercise 2:

- Write a value returning method that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 6 and 10 are passed as arguments to the method, the method should return 10. Your program should firstly prompt the user to enter two integers, and display the value that is the greater of the two. using Java programmingProgram61.javaWrite a program that prompts an employee to enter his/her hourly pay rate and hours worked last week. Call a method that takes these inputs as arguments. This method should calculate and print the employee's regular pay and overtime pay in currency format. The method should return the gross pay to main. The main method should print the gross pay in currency format.Sample Output (image below) Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below)java Finish the method called profit() that will take two int arguments and returns a String saying if there is a profit, a loss, or no loss. The first argument is the buyPrice value and the second argument is the sellPrice value. There is a profit if the sell price is more than the buy price. This is a return method with two int parameters

Choose one of the options:TrueFalse
- 2. Write a java program which will input an integer value from the user (Use Scanner class). Your program will have mathOper() method in addition to the main() method.The main() method will be responsible for:a. extracting the 1's digit (ones), the 10's digit (tens), and any digits larger than the 10's digit. For instance, if the input is 3562, the 1's digit would be 2, the 10's digit would be 6, and the remaining digits would be 35.b. call the mathOper() method with these 3 values,c. print the results to the screen.The mathOper() method will make the following calculations:a. Multiply the 1's digit by 7, subtract the result by 2 and then divide that by 5.b. Add 3.5 to the 10's digit, multiply the result by 4.3 and then divide that by 2.c. Subtract 5 from the remaining digits, multiply the result by 3, find the remainder after dividing that by 7, and then add 6 to the remainder value.d. Add the 3 values obtained from ‘a’, ‘b’, and ‘c’ operations.e. Return the final value.Sample output…Writing Methods that Return a Value in Java In this lab, you complete a partially written Java program that includes a method that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, −, *, /,or% ). The two numbers and the operator are passed to the method where the appropriate arithmetic operation is performed. The result is then returned to the main() method where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3.00 * 4.00 = 12.00 The source code file provided for this lab includes the necessary variable declarations, and input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Write the Java statements as indicated by the comments.

For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Additional requirements: Welcome the user with a message that you read from a file called "input.txt". ( inpu.txt file contains numbers between1-100.) Write the results to the terminal and also to the output file called, "output.txt" and remind the user to look at that file if he/she wants to. You only need to submit the designs, input/output files ( if applicable ) source code ( .java and not the project or the .class ) files of all the classes you'll implement and the driver program for the problem. ( Do not submit…Please be quick. 5. Define a method in JAVA that should take 4 numbers as the parameters and returns the average of all the numbers. The function return type should not be void i.e. the average value should be returned by the function.
