Aug 14, 2011 - i don't understand ,can u explain ?

saksepapirlim Says:

Aug 15, 2011 - @hemagokuYou can't pass any of the primitive data types as arguments to a generic method. The primitive data types: byte, short, int, long, float, double, boolean and char.

Sep 4, 2011 - I was wondering why he used the object types instead of the primitives... thanks for clearing that out!

awesomelemonade Says:

Sep 4, 2011 - I would rather make a generic print method instead of doing System.out........like thispublic *T* void print(T x){System.out.println(x);}I kind of had to replaced the star with the carets because youtube wouldn't let me put caretsbecause i am LAZY (that's why)

Oct 2, 2011 - java has unboxing and autoboxing so you can pass primative date types to a generic type. Only in java tho.

Nov 6, 2011 - i get this error message, can someone tell me whyException in thread "main" java.lang.Error: Unresolved compilation problem: The method print(T[]) in the type GenericMethod is not applicable for the arguments (int[])

Jan 24, 2012 - One question. How does the compareTo method determine which one of two Strings is greater?Thanks!

Jan 29, 2012 - lol templates

devilazpl Says:

Jan 29, 2012 - right sir, basic types: int and char arent supported by Templatesall you need to do is changeint to Integer[] iray  and char to Character[] cray;they are upgraded types that are better version (have more methods) of these basic ones

Luvu5evr Says:

Feb 5, 2012 - The data type passed to a generic method must be of a reference type, aka a class name. You cannot replace a generic type (T, E, etc.) with a primitive type (int, char, etc.). You can use wrapper classes (Integer, Character, Double, etc.)  to get around this. Using these classes will make an actual instance of the class with the value you passed to it and the value is immutable, e.g. Integer myInteger = new Integer(5); Here, 5 is the value of the Integer instance & is unchangeable.

Mar 22, 2012 - finally I understand why he wrote Integer[] instead of int[] :D

bloodsteam Says:

Mar 27, 2012 - Before watching this video I tried by myself to make a method that would do the job.public static void printMe(Object[] i) { for (Object x: i) System.out.printf("%s ", x); System.out.println();}Is this method equivalent or would it fail in some instances where bucky's would not?

Mar 31, 2012 - if you have Netbeans Installed type 'sout' then press tab and it will print 'System.Out.println("")'. Much faster

BizarroFreak9991 Says:

Apr 3, 2012 - As far as I can tell it would do the job just fine, since all Objects are child-classes of the Object class.Using a generic method though, you can also access the type (in this case T), f. e. to compare it. So you could handleT instanceof Integer // differently thanT instanceof String.
