Arrays

-Arrays in Java work differently than they do in other languages

-First declare the array

                        Int month_days=new int[12];

-Arrays can be initialized during declaration

-Multidimensional arrays

                        Int twoDp[][]=new int[4][5];

-Alternative array declaration

                        Int [] a2=new int[3];
