how can load properties file for one time and use in entire application

? No you don't . You read the file once. You store it in the hashmap. Then you hand that hashmap to whatever class needing the data.

getProperties() returns the hashmap, doesn't read the file.

Maybe I should have called the method getMap or something.

No, I won't.

I do not spoon-feed people. Maybe you'll have better luck with others.

Read the Singleton pattern, and come back when you have written some code and have specific problem(s).

I think that the resources are already cached, at least the ones from ResourceBundle.

The specification of ResourceBundle says:

"...Resource bundle instances created by the getBundle factory methods

are cached by default, and the factory methods return the same resource

bundle instance multiple times if it has been cached...."

my code is as folllows:

public class ClassicSingleton {

private static HashMap managers = new HashMap();

private static ResourceBundle instance = null;

protected ClassicSingleton() {

// Exists only to defeat instantiation.

}

public static readProperty getInstance() {

if(instance == null) {

instance = new ResourceBundle ();

/* logic to store property file in Static HashMap that is in variable managers*/

}

return instance;

}

public getHashMap(){

return managers;

}

//now i will call getHashMap() method in other classes like ....

}

class A{

void call(){

ClassicSingleton s=new ClassicSingleton ();

s.getHashMap();//calling HashMap

}

}
