i'm a beginner, Need help, Please!!!

I want to read number "a" from console and then store them in variable to use as passing to a different class (different .java file).

How do i code the 2 classes? thanks

public class PassedInMethod{ 

private int a; . 

 public PAssMethod(int a) { 
  a = a; // TODO: where to get the a? 
   System.out.println("a was passed in!"+a);


} 

public class Mainclass{


public static void main( String args[] ){
      Scanner input = new Scanner( System.in );

  int a;



  System.out.print( "Enter your nember: " );
  a = input.nextInt();



 PassedInMethod(int a);


}
