Parse and write JSON data in Java with Gson

Here i am showing you full examples of using following Gson streaming APIs to read and write JSON data.

As a pre-requisite, you are required to download the gson-2.1.jar

Create A GetJson.java class as bellow.

public class GetJson {

public static void main(String args[]){

GetJson obj= new GetJson();

obj.getJsonData();

}

public void getJsonData(){

//[{amount":9283.41,"balanceAfterTransaction":9283.41,"bank":"Bank_0160021000998","category":"OPENING_BALANCE","dateTime":"01/05/2017","description":"OPENING BALANCE","remark":null,"transactionNumber":null,"type":"CREDIT","valueDate":null},{"amount":100000.0,"balanceAfterTransaction":109283.41,"bank":"Bank_01698210009909","category":"OTHER","dateTime":"01/05/2017","description":" BY INST 51 : CTO12- 1 DAY LAT","remark":null,"transactionNumber":"KZT2","type":"CREDIT","valueDate":null}]

String inputLine = "[{amount\":9283.41,\"balanceAfterTransaction\":9283.41,\"bank\":\"Bank_0160021000998\",\"category\":\"OPENING_BALANCE\",\"dateTime\":\"01/05/2017\",\"description\":\"OPENING BALANCE\",\"remark\":null,\"transactionNumber\":\"trx009\",\"type\":\"CREDIT\",\"valueDate\":null},{\"amount\":100000.0,\"balanceAfterTransaction\":109283.41,\"bank\":\"Bank_01698210009909\",\"category\":\"OTHER\",\"dateTime\":\"01/05/2017\",\"description\":\" BY INST 51 : CTO12- 1 DAY LAT\",\"remark\":null,\"transactionNumber\":\"KZT2\",\"type\":\"CREDIT\",\"valueDate\":null}]";

String jsonData = "{\"bankTransactionList\":"+inputLine+"}";

int sizeList =0;

String amount =null;

String balanceAfterTransaction =null;

String bank =null;

String category = null;

String dateTime = null;

String description = null;

String remark = null;

String transactionNumber = null;

String type = null;

String valueDate = null;

try{

Gson gson = new Gson();

BankArrayList myData = gson.fromJson(jsonData, BankArrayList.class);

System.out.println("myDataList size >> "+myData.bankTransactionList.size());

sizeList = myData.bankTransactionList.size();

for(int i=0;i<sizeList;i++){

System.out.println("Amount >> "+ myData.bankTransactionList.get(i).amount);

System.out.println("balanceAfterTransaction >> "+ myData.bankTransactionList.get(i).balanceAfterTransaction);

System.out.println("bank >> "+ myData.bankTransactionList.get(i).bank);

System.out.println("dateTime >> "+ myData.bankTransactionList.get(i).dateTime);

System.out.println("description >> "+ myData.bankTransactionList.get(i).description);

System.out.println("transactionNumber >> "+ myData.bankTransactionList.get(i).transactionNumber);

System.out.println("type >> "+ myData.bankTransactionList.get(i).type);

System.out.println("valueDate >> "+ myData.bankTransactionList.get(i).valueDate);

System.out.println("--------------------------------------------------------");

}

}catch(Exception ex){

ex.printStackTrace();

}

Create A Bank.java class as bellow.

public class Bank {

public String amount;

public String balanceAfterTransaction;

public String bank;

public String category;

public String dateTime;

public String description;

public String remark;

public String transactionNumber;

public String type;

public String valueDate;

}

Create A BankArrayList.java class as bellow.

public class BankArrayList {

public ArrayList<Bank> bankTransactionList = new ArrayList <Bank>();

}

After run GetJson.java file, Result will be display as bellow image

Login with Google via OAuth Service

Google is providing OAuth Service. You can implement Google Login on your website so that user doesn't need to remember another password for your website. You will also get worthy email addresses to connect with users.

Here i will show you, how to implement OAuth Service in your web Application.

OAuth 2.0 Flow

1) User will click on Auth login link

2.) Google Auth server will show permission screen to user

3.) Once user accepts to the scope, It will send code to App Server ( Redirect URI)

4.) Once we got code, get access token by using client secret id

5.) Access User's Information using that access token

Get OAuth 2.0 Credentials from Google developer console

1.) Go to Google Developer Console https://console.developers.google.com

2.) Create Project and Open that project

3.) Go to API & Auth > Credentials > Create New Client ID

Login With Google plus JavaScript example code

Below code save as index.jsp page and run this jsp on web server.

<!DOCTYPE html>

<head>

<title>Login with Google Account</title>

function onSuccess(googleUser) {

var profile = googleUser.getBasicProfile();

gapi.client.load('plus', 'v1', function () {

var request = gapi.client.plus.people.get({

'userId': 'me'

});

//Display the user details

request.execute(function (resp) {

var profileHTML = '<div class="profile"><div class="head">Welcome '+resp.name.givenName+'! <a href="javascript:void(0);" onclick="signOut();">Sign out</a></div>';

profileHTML += '<img src="'+resp.image.url+'"/>';

profileHTML += '<div class="proDetails"><p>'+resp.displayName+'</p>';

profileHTML += '<p>'+resp.emails[0].value+'</p>';

profileHTML += '<p>'+resp.gender+'</p>';

profileHTML += '<p>'+resp.id+'</p>';

profileHTML += '<p><a href="'+resp.url+'">View Google+ Profile</a></p></div></div>';

//alert(profileHTML);

$('.userContent').html(profileHTML);

$('#gSignIn').slideUp('slow');

});

}

function onFailure(error) {

alert(error);

}

function renderButton() {

gapi.signin2.render('gSignIn', {

'scope': 'profile email',

'width': 200,

'height': 40,

'longtitle': true,

'theme': 'dark',

'onsuccess': onSuccess,

'onfailure': onFailure

});

}

function signOut() {

var auth2 = gapi.auth2.getAuthInstance();

auth2.signOut().then(function () {

$('.userContent').html('');

$('#gSignIn').slideDown('slow');

});

}

</script>
