i making program needs variable main method, when try import using main main = new main(); can't access variable. how can use variable in class? public class main{ public static void main(string[] args){ int = 10; } } public class someclass{ main mainclass = new main(); main.a;//i errors when } that why called "local" variable. available locally in scope defined in , can in no way whatsoever access variable unless add native code , mess dirty pointers. if need a in class , static main method need make a static member of class, pulling outside local scope like public class main{ static int a; public static void main(string[] args){ = 10; } } public class someclass{ main.a; } but think should book java , object oriented development before proceed, because example shows have not many clues both of them.
