Java with Google protocol buffer

Java Google protocol buffer step by step example with source code.

1.Overview of Java Google Protocol Buffer

Why GPB(google protocol buffer)? We can consider an example and application perform some read/write operation in the network. Each user writes and read some standard information. So, now the problem occurs in serializable. Serialization and de-serialization is CPU intensive operation that consumes a considerable amount of CPU resources. How we can serialize our application and get data from it.

Different Methods for

1. Java Serialization Method: use default java Seralizable interface that will take care effectively.
2. When java serialization not: when such an architecture occur where different language performs read/write operation in that case it will not work. (ex. Python, nodejs, C++, C etc).
3. We can used serialized XML to solve above problem, that now days adopted by rest web service.

Disadvantage of this is inside that network it is little bit bulk and its is human readable formation.
In that case some encoding and decoding operation should perform by user.

4. Use some ad-hoc conversion technique resolve such type of problem.

Another way to solve the above problem is to user Google protocol buffer:
Let me demonstrate you how we can create a proto file and generate language specific code:-

1. Step Create file having extension .proto file.
2. Install protoc compiler as per the required version that is protoc.
3. Now generate .proto to .java file.

protoc  - -java_out=C:\Users\SKY-O4DSol\Desktop\proto\ 
 --proto_path=C:\Users\SKY-O4DSol\Desktop\proto 
C:\Users\SKY-O4DSol\Desktop\proto\Employee.proto

Create proto file

option java_outer_classname = "EAddressBook";
message Employee {
  required string name =1;
  required int32  id   =2;
  enum PhoneType  {
     MOBILE =0;
     WORK   =1;
     HOME   =2;
  }
 message PhoneNumber {
   required string number=1;
   optional PhoneType  ptype = 2[default = HOME];
 }
 repeated PhoneNumber  phone=4;
 }
 message EmplyeeBook {
   repeated Employee emp =1;
 }

It generate .proto to .java file run command mentioned in step 3.
