发帖数: 1123 | 1 I am running the following on my Windows desktop --
1)I have successfully started a Linux-64-bit instance on Amazon EC2.
2)I have saved my private key file from Amazon EC2.
But I have been UNSUCCESSFUL in logging into my linux instance thru PUTTY on
my PC.
Have anybody here have experience in using Amazon EC2? If so, can anybody
share his/her step-by-step on how to log in to Amazon Linux instance from a
local Windows PC?
Any suggestion/tips would be greatly appreciated.
Thanks!

OK, would you agree that whether access to a static member should

some instance method from the same class? In other words, if
access to a static member needs to be synchronized, it needs to be

or by some code from somewhere else.

"abc", say S, then s1="abc" interpreted as assign the viarable s1 to

its parenting scope?), it must have searched its stack before creating a new
instance using String.equal() function, and found "abc" exists, s2="abc"
assigned viarable s2 to reference same instance S.
It will be really smart (or stupid) for the compiler to say "true".
