thanks bro it worked

Answer 2

remove the semicolon after area() and declare it static.....
here's your modified code :-

class Student
{
static int l=10,b=20,area;
static void area()
{
area=l*b ;
System.out.println("area="+area);
}
public static void main(String args[])
{
System.out.println("l="+l);
area();
}
}
