Welcome to null-land.

@SuppressWarnings("null")

Drop this code, entirely. Find something bettter.

kris131 · March 15, 2016

Soo you mean this vote is fail hm... i have try and anarchy vote i try to adapt to high five but errors.

SweeTs · March 15, 2016

Fix errors then. Basically you can even use frozen code for that. At least you will not see null crap.

Tryskell · March 16, 2016

Simply drop all suppresswarnings and fix them, as it should be done at first shot.

kris131 · March 16, 2016

L2jfrozen hard to adapt to high five too mutch files missing need to improvising and why null is bad where is the problem? (just for know)

SweeTs · March 16, 2016

Nothing is missing, just few methods are another/renamed. null - to suppress warnings relative to null analysis. You hide issues related to your code. Remove them and fix errors/warnings.

L2jfrozen hard to adapt to high five too mutch files missing need to improvising and why null is bad where is the problem? (just for know)

Null is bad because it creates issues, notably NPE like you show on your screen... Leading to code not working properly, as it stops to run when a NPE is found and not catched.

It's like if you asked why an headache is bad for your head...

kris131 · March 16, 2016

Edit : Look i remove the @SuppressWarnings("null") and i see error on in.close con.close isr.close

i fix but i dont know if again is the same.

Old :
finally{
try
{
con.close();
}

New : 
finally
{
try
{
if (con != null)
{
con.close();
}

Use try-with-ressources to avoid any memory leak. It avoids those ugly finally statements, and you don't have to care about closing the ressource too. Your project must support JDK 1.7 from memory.
