Calculator server client

BACAKU.txt

+Cara menjalankannya kan teman Sistem Informasi kek gini :
+1. buka file Calculator , trus bukalah cmd kan , baru ketik "start rmiregistry"
+2. buka file server , trus buka cmd, baru ketik "start java -classpath . -Djava.rmi.server.codebase=file:./ CalcServer localhost
+2002"
+3. buka file client, trus buka cmd, baru ketik "java -classpath . calc localhost 2002 tambah 1000 3000"
+
+untuk operasi kurang, , kali, bagi, modulo, pangkat, udah bisa juga. tinggal mengganti di java -clashpath . calc localhost 2002 GANTI 1000 3000
+
+NOTE : jalankan dlu rmiregistry, baru jalankan server dan client :)
+
+Maaf ya teman, cuma ini masih yang bisa ku bantu.
