Write $($define$)$ a public static method named longest, that takes two arguments $($all arguments will be Strings$).$ When this method is called, it should determine which string is longer, and return that string. If both arguments are the same length, then this method should return the first argument string.

Examples:

longest$("$abc$","$ab$")$ will return "abc"

longest$("$hello$",$ "goodbye"$)$ will return "goodbye"

longest$("$thursday$","12345678")$ will return "thursday"

You may wish to write some additional code to test your method.
