Groovy vs Java - For-Each loop

The latest version of Java (version 1.5 and later) have for-each loop support. Groovy have many type of powerful loops as well as it support traditional Java loops. This is very simple example for for-each loop.

Java way for implementing for-each loop

public class ForEachLoopDemo {
	public static void main(String[] args) {

		}
	}
}

Groovier way for implementing for-each loop

for(country in countryList) {
	println country
}

Getting key/value pair from JSON object and getting variable name and value from JavaScript object.

Hi, I had faced one issue like this. I have an JSON object but I don't know any key name but I need to get the all the key and corresponding value from JSON object using client side JavaScript.

I hope developers working in web application development might hear about MVC architecture. Almost all technologies provide support for MVC based web application development, but the success is based on many factors like reusable of the code, maintenance of the code, future adaption of the code, etc.., The success of the Spring MVC is “ Open for extension and closed for modification ” principle. Using Spring MVC the developers can easily develop MVC based web application.

I hope you have visited my part1 of my tutorial . Let’s see the steps for integrating hibernate framework into Spring MVC. Here I have used MySQL database. I have created one database called “ springmvc ” and created one table called “ user ” with userid, username, password fields. I have inserted some records into table like this. Step 1: Creating User POJO class. We need to create a User POJO class for mapping user table. Ok let’s create it. Step 2: Creating hibernate mapping xml file for user class. In hibernate we need to create hibernate mapping xml file for all domain class for mapping into corresponding database table. Instead of creating xml file you can use annotation for mapping domain class into database table. This is my mapping xml document created for mapping our user domain class into user database table. Step 3: Creating authenticate service class. The method “verifyUserNameAndPassword” pres...
