Semi-colon error that i cant solve....

Question

I AM GETTING A "; expected" ERROR, AT THE
"int calcpriority(timearv) { " LINE. AND THE "int AgeFac()" LINE
^ ^
I AM ASSUMING IT HAS SOMETHING TO DO WITH HOW I CREATED THESE TWO METHODS. (there are two arrows in the error message that point to the 1st bracket of each method)
PLEASE HELP.
import java.lang.String;
class Patient {
          int id;
          int age;
          int agefactor;
          int tl;
          String name;
          int priority;
          int timearv;
          int timenow;
          //constructor
          public Patient(int d, String n, int a, int s, int x) {
               id = d;
               age = a;
               tl = s;
               name = n;
               timearv = x;
               timenow = timenow + 2;               
//formula to calculate priority
          int calcpriority(timenow){
               int priority;
     priority = tl + (timenow - timearv) + AgeFac();
          }//constructor
public String toString() {
          String q = "Patient ID:"+id + "\t" + "Age:"+age + "\t" + "Trauma Level:"+tl + "\t" + "Name:"+name + "\t" + "Arrival Time:"+timearv + "\nCurrent Time:"+timenow + "Priority:"+priority;
          return q;
          }// of toString     
          public static void main(String[] args){
          Patient x = new Patient(1,26,5,"malcolm",1);
          int AgeFac()
               int agefactor
               if (age > 55){
               agefactor = 2;
               }//if
               else if (age < 12){
               agefactor = 2;
               }//else if
               else{
               agefactor = 1;
               }//else
          }//agefactor
               System.out.println(x);
     }//main
}//patient class

Answer 1

ok thanks for that, so i've rearranged the code and now i get the following error messages...."missing return statement"
}//AgeFac
and "missing return statement"
} (this one comes after the declaration of the calcpriority method...
import java.lang.String;
class Patient {
          int id;
          int age;
          int agefactor;
          int tl;
          String name;
          int priority;
          int timearv;
          int timenow;
          int p;
          int af;
          int AgeFac(){
               if (age > 55){
               af = 2;
               }//if
               else if (age < 12){
               af = 2;
               }//else if
               else{
               af = 1;
               }//else
               agefactor = af;
          }//AgeFac
          //formula to calculate priority
               int calcpriority(int timenow){
               p = tl + (timenow - timearv) + 2;
          //patient constructor
          public Patient(int d, String n, int a, int s, int x) {
               id = d;
               age = a;
               tl = s;
               name = n;
               timearv = x;
               timenow = timenow + 2;
               priority = calcpriority(timenow);
          }//constructor     
          public String toString() {
          String q = "Patient ID:"+id + "\t" + "Age:"+age + "\t" + "Trauma Level:"+tl + "\t" + "Name:"+name + "\t" + "Arrival Time:"+timearv + "\nCurrent Time:"+timenow + "Priority:"+priority;
          return q;
          }// of toString     
          public static void main(String[] args){
               Patient x = new Patient(1,"malcolm",26,4,1);
               System.out.println(x);
               //System.out.println(GetAgeFac);
     }//main
}//patient class
