How we can can call method without creating the object in java

and as a 3. solution;

you can address the object in a anonymous class:

public Foo(){

public void bar(){
  Object oObject = new Object();
  Object.addListener(new IListener{
      
       public void ObjectChanged(Event oEvent){
           Foo.this.funnyAction();
       }
    }
  }
}

}

It always depends on the context of calling an Object. Butt in general you should use as less public static as possible.

If you have a reference to an instance of the class (that someone else created for you) then just call the method. If, on the other hand, you haven't it then you have to make the method static (if possible).

Just in case you want to know how it works.
When a class is loaded and before any instances are created, the static variables are assigned, the static constructor is called and any static methods are made available. There is no need to create any instances:

class PlumPudding {
    // the first thing is the static variables:
    public static final boolean ADD_BRANDY = true;
    private static List<coin> coins;

    static {
        // second thing to happen is to run the static constructor:
        PlumPudding.coins = new ArrayList<coin>();
        PlumPudding.coins.add(new Coin(1));
        PlumPudding.coins.add(new Coin(2));
        PlumPudding.coins.add(new Coin(5));
        PlumPudding.coins.add(new Coin(10));
        PlumPudding.coins.add(new Coin(20));
        PlumPudding.coins.add(new Coin(50));
    }

    public static Coin getRandonCoin() {
       // now this can be called without creating an object
    }
}</coin></coin>

Dude,


First of all u should know the basics of OOPs.

What does object creation really means?
