A new feature to store classes was added in Java 8. In Java 8, there is a place known as MetaSpace where all the classes are kept. MetaSpace has replaced PermGen. The Java Virtual Machine used PermGen to store the classes prior to Java 7. Java 8 substituted MetaSpace for PermGen because...

Exceptions are thrown for problems with the OutputStream and for classes that should not be serialized. All exceptions are fatal to the OutputStream, which is left in an indeterminate state, and it is up to the caller to ignore or recover the stream state. ...

The larger the product ofN*Q, the more likely we are to get a performance boost from parallelization. For problems with a trivially smallQ, such as summing up numbers, the rule of thumb is thatNshould be greater than 10,000.As the number of computations increases, the data size required...

the same Reducer can be used directly on the stream or on each substream after the stream is grouped. This is a set of APIs similar to Collector, which not only solves some problems of Collector, but also provides more abundant features. The point is it is open, and the mechanism is ...
