Sir, regarding intern method and SCP , i think some mistakes are there in the way you explained. I am telling this based on what Durga sir taught in his videos. Please let us know which is correct.
According to him when you create string objects using new keyword, if the string literal is not present in the SCP , then first it is created in SCP and one is created in heap as well.

Base class foo method is private, private method we can t override. So it will call the base class foo method. There is a small mistake in talk. Thank you

[@rhehebbfb6386]

At 3:40 why printed baseclass.foo.? Foo method is present in derived class and it is runtime polymorphism so it should have printed derivedclass.foo?

[@bikashdatta9023]

3:38:56 If you got the answer, please explain.

[@rhehebbfb6386]

@@bikashdatta9023 foo method in base class have private access modifier and foo method in derived class have default access modifier..
If both classes have method with different access modifier then priority will be given to method with lower visibility..

[@bikashdatta9023]

@@rhehebbfb6386 I appreciate your time. Thanks.
Bro, please see this code snippet given below:
class Main{
public static void main(String[] args){
Main obj=new Child();
obj.foo();
}
protected void foo(){
System.out.println("main");
}
}
class Child extends Main{
public void foo(){
System.out.println("derived");
}
}
Here the output is "derived". But the visibility of foo() at Main class is less.

[@rhehebbfb6386]

@@bikashdatta9023 that's because private access modifier restrict the access to single class only.. by this principle jvm thinks that since the method can be accessed from that class only its behaviour cannot be changed (overridden) from other class.. so it simply treat both methods as two different methods.. so it does not take overriding into consideration.. and simply call the method in reference class..

[@meriyemelhajoui4083]

3:40 i didnt understand why the Program didn t throw an error because the foo() method is Private so isn't visible outside the Base class even if we assign the object to the Base reference ! any explanation please !

Hi Ramesh
Thank you for this content.
Any plan to provide design patterns

[@mohanreddy6355]

Please upload complete Java course

[@nareshe9906]

String s1 = "HELLO";
String s2 = "HELLO"; In your example both are having the same reference right how come s1==s2 is false ? it will return true..

[@hossamaddin7980]

thanks Ramesh

[@gnair9064]

The derived foo and base foo answer is wrong ? It's not printing derived but base time 3.38
