yes. absolutely  you can call JAVA code.

You can only start an application, invoking its main method, by invoking the java executable from the command line.

#!/bin/bash
javac -classpath /home/snowy/whateverthepathis/First.java

you can refer the samples in below URLs

Hi Ganesh,

Really for this..

For Example. i have the simple java code

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World");
    }
 
}

it will print "Hello World"
how will you take this ouput in shell script?
As you said

#!/bin/bash
javac -HelloWorld /home/snowy/whateverthepathis/First.java

#!/bin/bash
