I tried to write string to txt file in java .
When i checked my txt file in my windows,i encountered some problems.
If i use \n to change a new line ,i saw some black block appear the position that should change line and change line doesn’t work at all.

But when i use my android device to check the result ,it’s ok!!!
It’s wired,but i found a way to solve it.
answer:
use \r\n instead of using \n and the txt file you open on you pc will be ok :")

如果單純用\n來換行，用記事本打開檔案時
會看到原本應該換行的地方變成很多黑色小方塊
而且每行會接在一起，看起來很奇怪
不過用Java讀取這個文字檔時卻又是正常的

解決法很簡單，只要在\n前面加上\r
變成"\r\n"，在記事本上看就不會亂掉了
