java The literal of int 9223372036854775807 is out

I am working with data types at the moment in Java, and if I have understood correctly the type long accepts a value between the ranges of: -9,223,372,036,854 to +9,223,372,036,854,775,807. Now as you can see below I have create a Long variable called testLong, although when I insert 9223372036854775807 as the value, I get an error stating:

"The literal of int 9223372036854775807 is out of range.

#問題：爲何我在eclipse編譯器裏面輸入long abc= 9223372036854775807 ;而後會報

"The literal of int 9223372036854775807 is out of range.

這樣的錯誤呢？

##緣由####

貌似是編輯器檢查的時候會出現問題。那麼就是說編輯器去檢查的時候會默認把數字看成 int 類型來檢查。

##解決方法###

告訴編輯器，你所指定的並非int類型 ，在數字的後面加上後綴,若是float  加上 f/F，long 加上 l/L, double 加上d/D.
