can any friend tell me the answer of the question

What will happen if an image drawn out of the window coordinates???

the part of image that are not in window coordinate does not printed and not shown, if total image is outside from window coordinates then image does not shown nothing else no error shown,

need any more help any cs related subject feel free to contact me,

I think transient type variables are used when you donot want to access data if you are using Serialization. we use the keyword transient before the variable the we donot want to access variable when using serialization. and the reason is that we exclude the variables from serialize because some variable eg. DB connections ,Socket and Streams does not represent that state of an object rather it represents connections to external resources.
