| Is it possible to write JAVA program without including any
of the packages,such as "import java.io.*";
bcoz I instantly wrote a code without "import..." statement
and runned the program on command Line & it worked.
the code is:
class Person
{
String name;
int age;
Person(String s,int a)
{
name = s;
age = a;
}
accept()
{
System.out.println(name+"Hi!!!!!");
System.out.println(age);
}
}
class Demo
{
public static void main(Strings args[])throws
IOException
{
String name = args[0];
int age = Integer.parseInt(args[1]);
Person p = new Person(name,age);
p.accept();
}
