Java has 8 basic data types. Because these data types are not something on the object hierarchy, they pass values to the method without passing by reference. Creating or accessing a basic data type by means, can be encapsulated by the corresponding "package class".
EG:
INT data type package class integer.
Class cmdarg
{
Public static void main (string args [])
{
INT SUM = 0;
For (int Cut = 0; cut Sum = Integer.Parseint (args [cut]); System.out.println ("and" SUM); } } Javac cmdarg.java Java cmdarg 10 5 3 And for: 18 The PARSEIN () method in the Integer class performs a corresponding value of the corresponding value from the string. 10, 5, 3, store the string array args [], but does not incorporate the value to the code of the array, is it default? Is the default constructor of cmdarg? It feels not. This is some strange.
