关于java的文件写入的两个问题~~不去学海深仇了
<<始页  [1]  末页>> 

关于java的文件写入的两个问题~~不去学海深仇了有一个变量是account(String的)

建立account.sav格式的文件,应该怎么做?

要是把文件建立在save目录下面又怎么做呢?
myFile = new File("/save",account);
这样可以吗?

谢谢先

学海深仇的斑竹给我打八卦~~~
打死我也不去了

为什么不查API呢?API可是有用的咚咚啊。[乒乒乓乓 (5-26 1:04, Long long ago)] [ 传统版 | sForum ][登录后回复]2楼

ok, this is a basic questionfilename="/home/user/account.sav";
BufferedWriter writer=new BufferedWriter(new FileWriter(filename));
writer.write("whatever you want to write to the line"); writer.newLine();

//finally after u finish
writer.close();


use your own file name... windows file name like "C:/myfolder/saveing.sav";
or relative file locations...

and remember the call function must "throws IOException"

(引用 夜不归宿:account 是一个变量也可以这么写吗?)oh... my godString filename="xxx.txt";
String account="xxx.txt";

(引用 夜不归宿:account 是一个变量也可以这么写吗?)oh ... my godplease get a book and read the very basic part first before ask further more.

String filename="xxx.txt";
String account="account.txt";
String whatever="xxx.txt";


except "String", no more keyword, you can change of coz!!!!

(引用 Cdarkrider:oh ... my godplease get a book and read the very basic part first before ask further more. String filename="xxx.txt"; String ac...)恩,不要太激动~~~我的意思是这样的
String account=MyInput.readInt();
我要创建的文件是"accout".sav
就是说我想让account随着我的输入而变化
但是扩展名都是sav
这样也可以用上面的方法实现吗?

谢谢你的耐心解答和关注

(引用 夜不归宿:恩,不要太激动~~~我的意思是这样的 String account=MyInput.readInt(); 我要创建的文件是"accout".sav 就是说我想让account随着我的输入...)~~~难道是这样?
String account=account+".txt";
myFile = new File(newaccount);
对吗?

Hope he would find the API useful later (in CS1102?).

(引用 夜不归宿:~~~难道是这样? String account=account+".txt"; myFile = new File(newaccount); 对吗? )ok... see this
String account="your directoty/your filename without .txt";
account=account+".txt";
myFile = new File(newaccount);

and can you really "myfile=new File()"? i dont think so.
unless you decleared your own class.

note: pascal style is not working in Java
