Help with main function

Question

Can someone help me out with this? Im trying to create a main function out of this contructor.
public studentID()
int size; //hold returned values from box
int id;
int age;
size = Integer.parseInt(JOptionPane.showInputDialog (" Enter a nummber between 1 & 40")); //dialog box
recCount = 0;
idArray = new int[size];
ageArray = new int[size];
for(int i = 0; i <size; i++) //ask for values (size) times
id =
Integer.parseInt(JOptionPane.showInputDialog ("Enter an ID Number"));
age =
Integer.parseInt(JOptionPane.showInputDialog ("Enter an age"));
inputStudent(age, id); //calles method to put values in array
displayAll();
selectionSort(idArray, ageArray, size);
newNumberTable();
selectionSort(ageArray, idArray, size);
newAgeTable();
}

So what's the problem? Dump it all into the main method.
Actually I'd advise thinking carefully about whether it should really be in main(). Generally, IMHO, main should only bootstap an app. The real functionality should be in other methods that main() calls.
