can i keep arrays in parameters of method

Answer 1

Sure you can :) The following method takes an int array as parameter and prints all elements of it.

public static void printArray(int[] arr) {
for(int i=0; i<arr.length; i++){
System.out.println(arr[i]);
}
}

Answer 2

You can use both multidimensional array and jagged array as your parameters. :)
