How String class is thread safe in java? -

- 

public class threadstring extends thread {     string str = "abc";      public void run() {         str = "abc";     } }

if threads accessing above run method, reference "abc" pointing "abc" how works internally?

strings in java immutable. aren't modifying string, you're pointing value. point of view, it's thread safe - str either "abc" or "abc", can't invalid or illegal.
