I hope you will take into account that I am just learning Java 1 month

Answer 1

Here you have created an array of integers with a length of 2 using new int[2]. In Java, when you initialize an array of integers using new int[2], it initializes each element to its default value, which is 0 for int type. Same goes for arrays of char and string and as well you have not intitialized any of the arrays that is why you are getting their respective default values as output .
