Given two provided Lists of Integer called firstList and secondList, combine the elements of both Lists into one new List.
• Instantiate a new List, combinedList.
• Put each element from firstList into combinedList.
• Put each element from secondList into combinedList.
• Finally, print the elements of combinedList to the console.
