Object Creation in Static Method

[Ram Adsumalli]

Hi All,

In many real time applications, I observe the object creation is in the static method. And all the methods in that class will be non static. And all non static methods is used in the other classes like

  Classic.getInstance().getName  

What is the main advantage of doing this. TO my knowledge we can do this another way also. Just make the name() method as static and use that in another class without creation of object.Realtime application code base looks like this

  public class Classic {  
private static Classic instance = null;
private name;   
public Classic() {} 
 
public static Classic getInstance() { 
 
 if(instance == null) {  
       instance = new Classic();  }
      return instance;   }
}  
 
public String setName(pName){
this.name=pName;
}
 
public String getName(){
return name;
}

As the constructor is public singelton advantage is also ruled out.

Thanks,
Ram

From what I can see, the only difference is, you have two different ways of calling the getname() function

  
 
// the below is one line of code.
String A = Classic.getInstance().getName()
 
 
  

  
 
// As this is three steps.
Classic myclassic = new Classic
Classic.getInstance()
String A = myclassic.getname()
 
// 
 
 
  

If you want to reference the getname method non-statically, you're going to have to create an instance of that class, where as in the first example you use only static methods, so you don't.
