Whenever more than one thread accesses a given state variable, and one of them might write to it, they all must coordinate their access to it using synchronization. ↗
There have been 111 Justices in the Supreme Court of the United States. Only three have been women. If she is confirmed, Solicitor General Kagan will bring the Supreme Court to an historical high-water mark, with three women concurrently serving as Justices. ↗
In a recent decision of the Supreme Court, not made, however, by the full court, and concurred in by only four justices, it was held that the seller of a patented mimeograph could bind the purchaser to use only his ink in the machine, though the ink was not patented. ↗
Once an object escapes, you have to assume that another class or thread may, maliciously or carelessly, misuse it. This is a compelling reason to use encapsulation: it makes it practical to analyze programs for correctness and harder to violate design constraints accidentally. ↗
Compound actions on shared state, such as incrementing a hit counter (read-modify-write) or lazy initialization (check-then-act), must be made atomic to avoid race conditions. Holding a lock for the entire duration of a compound action can make that compound action atomic. However, just wrapping the compound action with a synchronized block is not sufficient; if synchronization is used to coordinate access to a variable, it is needed everywhere that variable is accessed. Further, when using locks to coordinate access to a variable, the same lock must be used wherever that variable is accessed. ↗
