how can we know which is narrower than other
if you are assigning one array variable to other variable instead of assigning values in array through index then it will not effect the original array
But i think 4th also correct. any comments?
Object type (not the reference variable's type), determines which overridden
method is used at runtime.
V)what is the difference of these
String s ="abcd";
String s = new String ("abcd");
