Cannot call 2 batch files .. executes only one batch and the program exists

Question

Hello,
I am trying to call 2 batch files from the program . due to some reason only first batch file is called and second one is not called . any idea why it is happening.
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import java.io.*;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
public class MyBatchFiles {
      public static void main (String args[]) throws Exception {
    StringBuffer output  = new StringBuffer();
    StringBuffer error = new StringBuffer();
    try {
               //call batch files
               Process Process=Runtime.getRuntime().exec("cmd /c start F:\\batch1.bat"); // Batch File Path
                   Process.waitFor();
                  BufferedReader inputStreamReader  = new BufferedReader(new InputStreamReader(cubeBuildProcess.getInputStream()));
               BufferedReader errStreamReader  = new BufferedReader(new InputStreamReader(cubeBuildProcess.getErrorStream()));
               output = new StringBuffer();
               error = new StringBuffer();
               for(String ProcessLine;(ProcessLine=inputStreamReader.readLine())!=null;)
                         output.append(ProcessLine);
               for(String ProcessLine;(ProcessLine=errStreamReader.readLine())!=null;)
                         error.append(ProcessLine);
               System.out.println("transformer output = " + output);
               System.out.println("transformer error = " + error);
               if (error!=null){
                         //calling batch2
                         Process Process2=Runtime.getRuntime().exec("cmd /c start F:\\batch2.bat"); // Batch File Path
                         Process2.waitFor();
                         BufferedReader Process_inputStreamReader  = new BufferedReader(new InputStreamReader(Process2.getInputStream()));
                         BufferedReader Process_errStreamReader  = new BufferedReader(new InputStreamReader(Process2.getErrorStream()));
                         for(String ProcessLine1;(ProcessLine1=Process_inputStreamReader.readLine())!=null;)
                                   output.append(ProcessLine1);
                         for(String ProcessLine1;(ProcessLine1=Process_errStreamReader.readLine())!=null;)
                                   error.append(cubeCopyProcessLine);
       }catch(Exception e) {
              e.printStackTrace();
}Thanks
Mike

It's your if statement. Why do you think it could be happening?
