According to java why can not this program be compiled?

[Varuna]

public class Lab1
{
static Person pers;

public static void main (String [] args){

//Lab1.Person pers = new Lab1().new Person();
pers=new Person();
pers.setFirstName("Bob");
pers.setLastName("Fields");
pers.printOut();
tester();
pers.printOut();
}

static void tester(){
Lab1.Person pers =new Lab1().new Person();
pers.setFirstName("Homer");
pers.setLastName("Simpson");
pers.printOut();
}

class Person
{
String firstName;
String lastName;


public void setFirstName(String newFirstName)
{
firstName=newFirstName;

}
public String getFirstName()
{
return firstName;
}
public void setLastName(String newLastName)
{
lastName=newLastName;
}
public String getLastName(String newFirstName)
{
return lastName;
}



//Behavior
public void printOut()
{
System.out.println("Name: " + firstName + " " +
lastName );

}
}


}

The above program can not be compiled the error message is "non-static variable this cannot be referenced from a static context
pers=new Person();" The problem I have in mind is pers is declared as an static variable and it is assigned an exact Person obect so even if it is an static variable it can find it's way to the to the Object, so even if things are this way according to my view why it can not be compiled

Varuna:confused:

You already had the solution in there. Unless there is a reason you uncommented this line?

Lab1.Person pers = new Lab1().new Person();

It worked when I changed the top part to this:

public class Lab1 {
    //static Person pers;

    public static void main(String[] args) {

        Lab1.Person pers = new Lab1().new Person();
        //pers = new Person();
        pers.setFirstName("Bob");
