Hi i am learning spring framework i came across the scope in tutorial that i am reading it said that if we declare a scope as prototype spring container create a new object for that class each time. so i have written a program to test it but no luck. could any one please help me. My code is

Main class

Shape interface has a method draw() which is implemented by Circle class

Point class is fallow

My spring configuration file is as fallows

The bean references are printing

same (which should be different because it is prototype)

from sysout. And one more thing how to configure a bean(point) that i set a message specifically to it to the particular class(center).

Bean circle is a Singleton, you have

<bean id="circle" class="org.malli.Circle" >
<property name="center" ref="zeroPoint"/>


Which means the zeroPoint injected into that circle will be just one zeroPoint and always that same zeroPoint. It won't get a new one each time because Circle is created only once and its center property will only be set once. So therefore the life of the circle, which is the entire application duration will always point to the same zeroPoint assigned when it was created.

With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
