Question

Create a program called TennisWinPercentArray.java.  

In the main method

• Ask the user for the name of a tennis player

• Ask the user for the number of years the tennis player has played competitive tennis. Use this value as the size of a double array.

• Ask the user for the year the tennis player began playing competitive tennis

• In a for loop, ask the user to enter the number of wins and losses starting from the first year of play and store the win percentage (wins/(wins+losses)) value in the array. The element at index 0 will store the win percentage for the player’s first year.

• Call the method printWinPercentage with the player’s name, the first year of play and the array

In the printWinPercentage method

• There should be three parameters: a String for the player’s name, int for the first year of play, and a double array

• Display the player’s name

• Display the year and the win percentage for each year with 1 number after the decimal.
