SingleToneDessignPattern

A singleton in Java is a class for which only one instance can be created. It provides a global point of access this instance. The singleton pattern describe how this can be archived.

Singletons are useful to provide a unique source of data or functionality to other Java Objects. For example you may use a singleton to access your data model from within your application or to define logger which the rest of the application can use.

in this example i have a use singleton design pattern in create only one instance

private static final SingleTonPatWithConst instance = new SingleTonPatWithConst();

//private constructor to avoid client applications to use constructor
private SingleTonPatWithConst(){}

public static SingleTonPatWithConst getInstance(){
    return instance;
}

I have use this pattern in dialog create in application and use this dialog as a instance and when create a dialog using instance and whole
application have a only one instance.


you can use this way

/*
SingleTonPatWithConst.getInstance()./*Your singleton method name*/;
*/
