Craeting Stub

Question

Hi All,
I got a problem please try to help me out,iam sending a java file in which i had done some coding but now stuck in middle,
what iam trying to do is that if i got family.java file and it got x number of public methods and i like to create a stub for this
family.java file so i want all these public methods with its return type,parametrs ,Excetpion the method throws means the whole
signature of the public methods to be written in its stub. for example if family.java got this public method
public String[] gotStr(int[] hope,String name,Member mm) throws Exception,
so this whole public method should be writtrn as it is in its
familystub.java file .
can anybody please help me out that what should be done in this CreateStub.java file so that i can get all the public methods of family.java files to familystub.java file using CreateStub.java file as tool.
This is what i had done uptill now

hi dpz,
i found the solution something like this got through the CreateStub class .
import java.io.*;
import java.util.Vector;
import java.lang.reflect.*;
import java.lang.Class;
public class CreateStub{
     Family thisClassMethods ;
     Method[] methodsToBeRetrived;
     Field[] classFields;
     Vector publicMethods;
     public CreateStub(){
          thisClassMethods = new Family();
     public void     getPublicMethods(){
          methodsToBeRetrived = thisClassMethods.getClass().getMethods();
          classFields = thisClassMethods.getClass().getFields();
          publicMethods = new Vector();
     for (int i=0; i<methodsToBeRetrived.length; i++) {
     String str = methodsToBeRetrived.toString();
               if(str.indexOf("Family") != -1){
                    //System.out.println("The str: "+str);
                    //System.out.println("The index : "+str.indexOf("Family"));
                    String temp = str.substring(0,str.indexOf("Family"));
                    //System.out.println("The temp : "+temp);
                    //System.out.println("The str index : "+ str.indexOf("Family"));
                    //System.out.println("The family length : " + "Family".length());
                    str = str.substring(str.indexOf("Family")+"Family".length()+1);
                    str = temp + str;
                    //System.out.println("The final str : "+str);
                    temp = str;
                    publicMethods.add(str);
     System.out.println ("The methods are ");
     for(int j=0; j< publicMethods.size(); j++){
               System.out.println((String)publicMethods.elementAt(j));
          writeToAFile();
          //return classMethods;
     public void writeToAFile(){
          File temp;
          FileWriter writer;
          String tempFileName = "Family"+"Stub"+".java";
          try
               temp = new File(tempFileName);
               try
                    writer = new FileWriter(temp.getPath());
                    String stringToWrite = "//-*************************************************\n";
                    stringToWrite = "//-*************************************************\n";
                    stringToWrite = "public class FamilyStub \n{\n\t\t public FamilyStub() \n\t\t{\n\t\t}\n";
                    stringToWrite += "\t\t"+"//++++++++++++++++++++++++++++++++++++++++"+"\n";
                    stringToWrite += "\t\t"+"//++++++++++++++++++++++++++++++++++++++++"+"\n";
                    for(int j=0; j< publicMethods.size(); j++){
                         stringToWrite = stringToWrite + "\t\t"+ (String)publicMethods.elementAt(j) + "\n";
                         stringToWrite += "\t\t{"+"\n\n\t\t}\n";
                         stringToWrite += "\t\t"+"//++++++++++++++++++++++++++++++++++++++++"+"\n";
                         stringToWrite += "\t\t"+"//++++++++++++++++++++++++++++++++++++++++"+"\n";
                    stringToWrite += "}";
                    writer.write(stringToWrite,0,stringToWrite.length());
                    writer.close();
               catch(Exception e)
                    System.out.println("Problem in writting the file");
          catch(NullPointerException e)
               System.out.println("Null Pointer for tempFileName");
     public void printClassName(Object obj) {
System.out.println("The class of " + obj +
" is " + obj.getClass().getName());
     public static void main(String args[]){
          CreateStub m = new CreateStub();
          m.getPublicMethods();
hey dpz now can you tell me how can i use this class for many more classes as this is the solution for single Family class now if i want to use this class for many more classes how can i do that
