Hi Friend,

Here we are sending you some sample program code for running batch (.bat) file in Java. We have used "exec()" command for running the batch file. Suppose we have created a batch file "notepd.bat" which calls the notepad and this is responsible for opening a notepad.

notepd.bat
==========

echo "This would open notepad"
CALL notepad

Our java class is "CallBatchFile.java" who runs the bat file.
CallBatchFile.java
==================
import java.io.*;
class CallBatchFile{
public static void main(String args[]){
try
{
System.out.println("Start Running the batch file");
Runtime.getRuntime().exec("notepd.bat");
System.out.println("Completed");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

Output :
C:\>javac CallBatchFile.java

C:\>java CallBatchFile
Start Running the batch file
Completed
and one notepad window will be open.

Thanks & Regards
