How the control flows through the Java program during compilation?

[Tabassum Momin]

Hello everyone, I would like to know about how the control flows, while compiler compiles the JAVA program

Let me take a simple example.

public class Demo
{
public static void main(String arr[])
{
Test tst= new Test(); // line 5
tst.display(); // line 6
}
}

class Test
{
void display()
{
System.out.println("Hello");
}
}

-->I would like to know that when compiler come across line 5 and 6, how does it come to know that the class Test and it's method display() exist.

Here is your code, properly formatted in code tags:

public class Demo
{
  public static void main(String arr[])
 {
   Test tst= new Test();        // line 5
   tst.display();                   // line 6
 }
}

class Test
{
  void display()
 {
   System.out.println("Hello");
 }
}

When it gets to lines 5 and 6, it DOESN'T know that the class and method exist. But it's not to hard to say "Well, I better be able to figure it out before I'm done. I'll just remember these two things, and I'll check again before I'm done looking at everything else that they are somewhere.".
