Serialize to File 

Google-gson is a java library from Google for encoding and decoding JSON text. Get the latest binaries from http://code.google.com/p/google-gson/. The following example shows serializing a JSON string to file.

File Name  :  
com/bethecoder/tutorials/google_gson/common/Student.java 
   
package com.bethecoder.tutorials.google_gson.common;

import java.util.Date;

public class Student {
  private String firstName;
  private String lastName;
  private int age;
  private String hobby;
  private Date dob;

  public Student(String firstName, String lastName, int age, String hobby,
      Date dob) {
    super();
    this.firstName = firstName;
    this.lastName = lastName;
    this.age = age;
    this.hobby = hobby;
    this.dob = dob;
  }
  
  public String getFirstName() {
    return firstName;
  }
  public void setFirstName(String firstName) {
    this.firstName = firstName;
  }
  public String getLastName() {
    return lastName;
  }
  public void setLastName(String lastName) {
    this.lastName = lastName;
  }
  public int getAge() {
    return age;
  }
  public void setAge(int age) {
    this.age = age;
  }
  public String getHobby() {
    return hobby;
  }

  public void setHobby(String hobby) {
    this.hobby = hobby;
  }
  public Date getDob() {
    return dob;
  }
  public void setDob(Date dob) {
    this.dob = dob;
  }

  public String toString() {
    return "Student[ " +
      "firstName = " + firstName +
      ", lastName = " + lastName +
      ", age = " + age +
      ", hobby = " + hobby +
      ", dob = " + dob +
      " ]";
  }
}

package com.bethecoder.tutorials.google_gson.tests;

import java.io.FileWriter;
import java.io.IOException;
import java.util.Date;

import com.bethecoder.tutorials.google_gson.common.Student;
import com.google.gson.Gson;

public class SerializeToFile {

  /**
   @param args
   @throws IOException 
   */
  public static void main(String[] argsthrows IOException {
    Gson gson = new Gson();
    FileWriter fileWriter = new FileWriter("Student.json");
    Student stud = new Student("Sriram""Kasireddi"2"Singing"new Date(11046));
    
    gson.toJson(stud, fileWriter)
    fileWriter.close();
  }

}
   

It gives the following output,
Student.json
{"firstName":"Sriram","lastName":"Kasireddi","age":2,
	"hobby":"Singing","dob":"May 6, 2010 12:00:00 AM"}
