3:55 Putting a primitive variable inside the object, this concept is called boxing(in OOPs), in java, it's called wrapping... int i=5; Integer ii = new Integer(i); //passing primitive variable i inside the object. Taking out the value from the object is called unboxing/unwrapping.

Worthy classes. Thank you so much for making my time effective. Sir, could you please make a class on finalize () , garbage collection and related topics?

@theblindprogrammer 2 жыл бұрын

I thought you didn't have to worry about garbage collection in Java since the complier takes care of that?

Just an update, the constructors new Integer() and new Float() are deprecated in Java 9.

Just one question. If wrapper class are slow why do collection framework and generics prefers using them?

@brandyplays6134 4 жыл бұрын

because to make our lives miserable

@dexternepo 4 жыл бұрын

Because primitive types are faster than objects. They consume less memory as well.

@gopalbharadva9623 5 жыл бұрын

in your example "value" is a reference variable not object. you say it around 5:25 minute

@theblindprogrammer 2 жыл бұрын

In Java whenever you see the "new" keyword, that means a pointer to a memory space. It is like me asking you where your friend lives, and you saying he lives 123 Main st; whenever you say an address, you are basically pointing where a data lives. When I instantiate a Human object like Human mike = new Human(); what I am doing is pointing to where the memory is

i have an small question. When an java program runs then which is start the object or the class ?

@HetTrivedi 6 жыл бұрын

When java program runs, the main(String[] args) method is executed. If you have an object (For example; Demo d = new Demo();), then the Demo class is loaded first, and then an instance of Demo class (i.e. 'd') is created.

Just a quick question , you told, Since parseInt is a static method we need to use the classname.parseInt and you had mentioned Integer.parseInt but i'm seeing the class name as WrapperDemo

@jvsnyc 3 жыл бұрын

parseInt(), decode() and valueOf() are members of each wrapper class per se, e.g. Integer or Long.

Technology updates every day, In 2020 Eclipse says Integer wrapper is depreciated since version 9.

Use this instead. int x = 10; System.out.println(Integer.valueOf(x));

Wrapper class probably not feasible after version 9
