declare the main class in the MANIFEST file of the .jar file and call the required classes from the main.

(1) i have a java app [ getnewkey.jar] , this app request user to input a key [eg AUIL01-1]    ---->  Consider you have the class 'MainFile.java', declare this 'MainFile' in the MANIFEST file. So watever you give to the .jar file will goto the main method of this class in the args[].

(2) i have a java class [key.class ]this generates a new key based on the last key.   ---> Declare one public method (say generateKey) which takes the input key and returns a new output key as type String.

 (3) i Want the java app to call the java class file once the user enters the key in the java app . The java class generates a new key i want to return this to the java app and display ( eg: 'New Key ... BUOPQ   ----> Now from the MainFile.java main method, instantiate this key.class and call the generateKey method.

Eg. public class MainFile{
  public static void main(String args[]){
    String inputKey = args[0];
     key mykey = new key();
    String outputKey = mykey.generateKey(inputKey);
System.out.println(outputKey);
   
 }
