Hi, I don't know if it's because my English is not good, I don't understand this sentence which is one of the right statements about EL implicit objects:
"The implicit object param is a Map that maps parameter names to single String parameter values."
What does the "single" word mean here? Does it mean only one value for each name? (If so, I don't think this statement is right.) Or it means that the values can't be String array? Maybe this is a silly question, but I am really confused. Thank you.
