Use Java, write in first-year beginner level. Please do 2 of them and I will give a thumb up otherwise would be a thumb down. Use a line comment at the top to write the problem description. Use meaningful variable names.

Problem 1: isInValidNumber Method.

The static method isInValidNumber should accept a double number as its argument and return the value true, if the number is out of the range of 10 and 50, boundaries excluded. It will return false otherwise. Use this method in an input validation loop in the main method.

Problem 2: Pennies for Pay

Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day.

The program should display a table showing the salary for each day, and then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies.

Input Validation: Do not accept a number less than 1 for the number of days worked.
