Method parameters defined in Java (final String ... args)

is defined as final to prevent parameters from being modified in the method class.
Final String ... args is a new feature of the JDK, which is a variable-length parameter. The compile time is interpreted as: public dcmexception (final String ID, final string[] args),

But in programming you can give the method parameter Dcmexception ("id", "arg1", "arg2", "Arg3" ...) This makes it easier for programmers to assemble arrays as parameters.
