Answer 3

output is some ascii value

Answer 4

Yeah that's what I'm saying it considers an array as a typical object and returns default string i.e a'[ representing an array, followed by a character representing the primitive data type of array followed by an Identity Hex Code. So if you wanna print an array as a string you have to use Arrays.toString() method from util class
