Description Write a Java program that requests a user to enter a flight code. The program should verify that the user enters a valid flight code. A valid flight code begins with 2 or 3 capital letters and is followed by 3 or 4 digits. This program should use the .matches(<...>) method with a regular expression. If the user does not enter a valid code, your program should continually request that they enter a valid flight code until a valid code is entered. NOTE: Your output should exactly match the expected output. Sample Run of Program 1 EI320 //user input Flight code is valid //output based on value of code Sample Run of Program 2 rea4121 //user input Flight code is NOT valid //output based on value of code REA4121 //user input Flight code is valid //output based on value of code
