I am a novice programmer and i was wondering if i can use strings in the switch statement.
i was wondering if this type of code would work:

switch (codon){
    case "GGG": return "Phe ";
    case "GGU": return "Met ";

(im writing a program that translates RNA code into its corrisponding chain of amino acids, aka a polypeptide)

if ("GGG".equals(codon))
  return "Phe ";
else if ("GGU".equals(codon))
