You can use Java's exec() capabilities to start a Perl process just like you can run other applications. You must handle the resulting standard in, out and error streams as discussed many times in this and other forums.
You will have to have a Perl interpreter installed on your system, but nothing extra on the Java side.

You can also search for similar scripting languages to Perl available for Java. For example, the article below says Sleep and Perl is similar:

Hai All,
I executed the following piece of code

try{

Process p1 = Runtime.getRuntime().exec("cmd.exe /c perl.exe -S
samplePerl.pl");

} catch(Throwable event){
System.err.println("Exception occured"+e);
}

It is not giving the output.can anyone tell the error in this or what I have to do further.
Thanks in advance

Where did you expect the output to go?
See the Javadocs for java.lang.Process - paying especial attention to the discussion of the input, output and error streams.
