using java variable from another file method in run of other file

I have two files like this:

Client.java:

public class Client implements Runnable {
//code

   public void run() {
   //more code
       Crypt cls = new Crypt();
       cls.decrypt(request,key,type);
       //print "val" here.
   //more code
   }
}

And then the Crypt.java file which is like this:

public class Crypt{

    public static byte[] decrypt(byte[] val, byte[] key, int type)
    {

        //val assigned here
        // the following is used to assign it.
       val[length - len - 1] ^= key[8 + (((byte)(key[8 + b] + key[8 + a])) & 0xFF)];


      return val;
    }   

}

I need to be able to access the val variable in in the Client.java file again after it has run through the Crypt.java file.

I've tried cls.val and cls.decrypt.val but I don't know how to get it working.

Thanks for the help!

Your dycrypt() method in class Crypt is a static member of the Crypt class. So you don't need to create an instance of Crypt class in Client class like - 

Crypt cls = new Crypt();
cls.decrypt(request,key,type);

You can just call the decrypt() method using the class name and store the returns into a byte[] array - 

byte[] vals = Crypt.decrypt(request, key, type);

Then using a for loop/for-each loop you can print the vals array - 

for(byte each : vals){
   System.out.println(each);
}

Simply assign the return value of dectypt to a variable and use it. 

byte[] res = cls.decrypt(request,key,type);

Since your decrypt() method returns a value, assign it to a variable when you call it.

byte[] result = cls.decrypt(request, key, type);

and then your result variable is the value you want, in Client.java and ready to be used.
