Sonetimes jvm will not distroy after declaring the reference variable as a null bcz when ur heap memory enough available is then garbage collector not be destroyed and not only null value eligable for garbage collector cycling problem and reassign the reference that time also ur object eligible for garbage collector 👍
7:00 string obj create extra obj and occupy memory because string immutable. But string builder is mutable and it will reflect the change in same obj so main advantage of this to save memory.
3:47 String literal is store in string constant pool and string object which is created with new keyword stores heap area and string constant pool both.
For the last question the answer would be URI versioning, Versioning using headers - Accept/Request Header. URI versioning is most common in which we create different api for new schema. So that old api's remain unaffected.
password always stores in char cuz when store in String then it will create 2 object one in heap and other in sop and no ref variable is pointing that object so hacker can hack that

@@noogler123 in short: if you just print char arrays, it wont print the characters (unlike String does), but it will print the memory location (which doesnt help to find out the password).
so the answer is to use the char array for storing password because string is immutable...whenver u create any object it will be allocated in heap as well as string constant pool. jvm garbage collector can delete the unused object in heap but not in scp and when u store the pwd in char and string format. when u print the the object...it will print the address location in char array but will print the value in string format. thats why char array is preferable.

Can someone answer correctly how to handle exception when method1 calling method 2 and method 3 and any failure in method 3 how do you handle and display to client ?
this is the concept of exception propagation. For an example - you are consuming the response and transforming the object into your model having various child classes. Now, you got some missing data on child entity but that is required. So on saving the whole object, you will get exception on child class but to be displayed on parent entity. Such type of scenarios are handled by exception propagation.

Because she want to hirre him..🤣🤣
Requirement hogi bro. Aise hi hota.. my friend was hired on 14 lac package. Usse to ek bhi legit question nahi kia. Class 12 vale question kie.
Just for clarification: "decrypted" passwords never go to the string pool. Only literals go to the string pool.
So where it will go sir ?
Hahahahaha
S it will go to the heap memory only
Seems 3+ years interview, Tested in design patterns concepts also
I think, we have to give this exam within 3-4 months of joining Accenture.
For the last question the answer would be URI versioning, Versioning using headers - Accept/Request Header. URI versioning is most common in which we create different api for new schema. So that old api's remain unaffected.
JVM will create new String object for every manipulation as it is immutable
password always stores in char cuz when store in String then it will create 2 object one in heap and other in sop and no ref variable is pointing that object so hacker can hack that
But if we write like this String s = "Password" then only one object is creates in scp only and s will be pointing to that

2:23 charArray is the best way to store password
Better store password on char[] instead of Strings.
Thats what she wanted to hear.
byte[] also good
Correct !!
What is the reason that we should store it in char array
@@sau5040 because String is stored in string pool and password will be stored in the pool.

Use character array for savings password. Its not easily readable even if it is logged.
Can you please elaborate more.
I understood your approach, but how it is safe. I wants to check practically.

questions are very good very much help full
Factory pattern help us to achieve loose coupling same as dependency injection or IOC
I should used char data type for password
Being a fresher I will be able answer 65% answer . Is that a good level as a fresher ?

For decrypted password always go for byteArray than string for the reasons mentioned by her
why byteArray bro?
It is not safe to store in a string, possible a stringbuffer data structure or stringbuilder
No, its always recommended to use char[] for storing the passwords.
I think this is at least for 3 years of experience.
That's what ...i am a fresher ..going above my head
Experience range???
I hope she is expecting Array for password storing..
password always stores in char
@@usamaansari7903 yes I mean char array
Use Properties class for saving password
I need this girl to interview me.....🤔🙅☘️🥗
From 2:23 question, what's the correct answer for it ?
Char []

When we decrypt it will be of byte array right?
You need to store in char array, which will store the values in blank . So the right answer is char[]
