How to use utility --- intToShortBytes

Question

does any one used this method before??
I have tried :
int IntVal = 355;
byte[] twoByte = new byte[2];
twoByte = IntVal.intToShortBytes();
I got error saying
--->> Int cannot be dereferenced
I guess I used it wrongly.... can anyone correct me on the usage of this method??

Answer 1

byte, char, short, int, long, float, double, boolean are all primitives. Unlike objects, they don't have methods or member variables associated with them. Dereferencing is when you use the dot to get to the object that a reference variable points to.
String str = "abc"; // str is a reference variable
System.out.println(str.length()); // I dereferenced str to get to its length method I don't know what class has the intToShortBytes method, but I assume it's Integer, so you'd do something like Integer i = new Integer(123);
byte[] bytes = i.intToShortBytes(); or else maybe it's a static method, so you'd do byte[] bytes = SomeClass.intToShortBytes(123); Check the docs for that method. And you probably ought to go through one or more beginner tutorials on Java.
