class is placed in a private namespace associated with the source of the applet. Then, the classes that are loaded into the ClassLoader are validated by the validator. The validator checks to see if the class file format adheres to the Java language Specification, ensures that no stack overflow (stacks overflow) or underflow (underflow) is present, and that the parameters passed to the bytecode directive are correct.What is the 56.applet security Man

, you should use the random list. If you need to quickly access elements randomly, you should use the arraylist.If the program is in a single-threaded environment or the access is only performed in one thread, the efficiency of non-synchronous classes is high. If multiple threads may operate on one class at the same time, synchronous classes should be used.Pay special attention to the operations on the hash

The Java1.5 adds new features:Variable parameters:For cases where the parameter number is indeterminate and the type is determined, Java handles the mutable parameter as an array.Note: The mutable parameter must be in the last item .When there is more than one variable parameter, there must be one that is not the last, so only one variable parameter is supported .Because of the variable number of arguments, Java
