int boy ;
return boy;
}

}

Answer 1

instead do it like this..

import java.util.*;

public class Program
{
public static void main(String[] args) {
hassan me = new hassan();
amin him = new amin() ;
me.boy(System.in.nextInt());
him.mama();
}
}

public class hassan {

public hassan (){}

public static int boy (int x) {
int boy = x;
return boy;
}
}
public class amin {

public amin(){}

public void mama() {

System.out.println ("hay mom") ;
}
}

or just look this one

import java.util.*;

public class Program
{
public static void main(String[] args) {
hassan me = new hassan();
amin him = new amin() ;

Scanner scan = new Scanner(System.in);

him.mama();
System.out.print( me.boy(scan.next()) );

}
}

public class hassan {

public hassan (){}

public static String boy (String x) {
String boy = "I\'m "+x;
return boy;
}
}
public class amin {

public amin(){}

public void mama() {

System.out.print("hay mom, ") ;
}
}
