We know that Java supports built in multi thread environment. consider a particular OS supports only single thread environment. In this type of OS, is it possible to use Java's Multithread. Did you understand what am saying??
In a single thread environment(which supports by OS) is it possible use Java's multi thread??
If there is a JVM available for such an OS which fully implements the Java SE specifications, then yes, you can use multithreading - otherwise it would not be a complete Java SE JVM. See green threads.
Just to be safe, make sure you don't mix up single threaded and containing a single processor. An OS running on a machine with only one processor can still run multiple threads. They just may not be executing at the exact same time, although the alternation is usually so fine grained you won't even notice.
