String is immutable. So,
if you say

both a and b points to same foo" in the memory. But, when you declare a string with 'new', as in c, It will not refer to the same object in the memory.
It will create a new object and points to that.
you can test a and c with == operator.

here is the code:

Thanks for the reply.
I learn that ArrayList is fast for indexed access.
what if i need to iterate through complete collection (search) ? which one is fast?
for example, my collection object is having all the employee names in it. I need to search for a particular(unique) name say "JHON", which one is more efficient and fast?
Which collection to use to print all the names where first name is JHON? there might be multiple employees with first name as JHON.

Can any one please help?

Thank you for your reply.
I have already done with the coding of analyzing the string and putting it into different String Array.
My problem is for Validation. How to validate each segment ?

Price is with in Veg Segment. Veg Segment is with in Meals.
So, first i need to validate the Meals. IF validation fails there, no need to validate other items.
If validation for Meals is success, Then it should move to veg segment to validate. how to do this....I want to way to call the validation process......

Hi all,
I have a strange requirement.

I have a String like: Meals(veg(soup&starters(price=40 || 50))nonveg(seaFood)delivery=parcel || ready_to_eat)

I parse this string and put all the values with in veg to a string array

String[] veg = {soup,starters}
String[] nonveg = {seafood}
String[] delivery={parcel,ready_to_eat}

Now, my question is:
I need to validate these values.
Meals = it should be validated against uppercase or lowercase, and correct spelling. if it fails, no need to validate other stuff.

If Meals is validated succssfully, I need to validate veg in such a way that:
veg should have only soup and starters with in that. nothing else.
if it has veg(salad) then, the validation should fails and send "fail" as response.

Is there a best design to do this ? My desing as follows:

My problem is how to call the methods or the sequence of methods? so that the complete Order String is validated.
do i need to put the method calls in if...else or in switch statement or is there any other way? I want the best desing for this issue.

Please help me?
