What is difference between singleton and prototype bean?

Question

i\'m new to spring and i read this :

Basically a bean has scopes which defines their existence on the application

Singleton: means single bean def

Answer 1

1. Singleton scope is default.
2. Singleton beans are created during initialization of app context and same bean is returned always.
3. Prototype bean is created when ever it is called. Each time it is called we get a new object.

Note : Bean with any scope will be created if it is referred by other beans and called using Application context.

Example code to check this.

public class PrototypeClass {

        PrototypeClass()
        {
            System.out.println("prototype class is created"+this.toString());
        }

    }

This will print the relevant text when constructor is invoked.

for the below code

for(int i=0;i<10;i++) {
   PrototypeClass pct= (PrototypeClass) context.getBean("protoClass");
}
