List<Long> listOfLong = new ArrayList<Long>(Arrays.asList(1, 2, 3)); In the example,1,2,3areintvalues.Arrays.asList(1, 2, 3)creates aListin the type ofList<Integer>.Since Java castsinttolongautomatically, we might want to pass aList<Integer>toArrayList<Long>‘s constructor, attemp...

This approach to initialization is simple and straightforward. It has the limitation that every object of the type will get these same initialization values. Sometimes this is exactly what you nedd, but at other times you need more flexibility. Constructor initialization There’s one thing to keep...

This initialization is done by calling the method:final void initSign(PrivateKey privateKey) This method puts the Signature object in the SIGN state. If instead the Signature object is going to be used for verification, it must first be initialized with the public key of the entity whose ...
