String中的内容输出到txt文件中去

[liang5wu]

假设String str = "adsasdasdasd";
如何创建一个文件名为变量的txt文件，里面只有str
谢谢

[飞跃颠峰]

String filename = "1.txt";
String str = "adsasdasdasd";
RandomAccessFile raf = new RandomAccessFile(filename,"rw");
raf.writeBytes(str);
raf.close();

[liang5wu]

我自己也写了个


public void writeFromBuffer(String str, String outFileName) throws IOException {
OutputStream os = new FileOutputStream(outFileName);
PrintStream ps = new PrintStream(os);
ps.print(str);

PrintWriter writer = new PrintWriter(new OutputStreamWriter(os));
writer.flush();
os.close();
}
好像比你复杂
有什么区别吗？
哪个效率高

呵呵，你自己觉得呢

String str = "我爱csdn，但我更爱java";
FileOutputStream fos = new FileOutputStream("C:/poem1.txt") ;
DataOutputStream dos = new DataOutputStream(fos) ;
dos.writeUTF(str) ;
dos.close() ;

RandomAccessFile这个还真没用过呢

这种方式怎么会在前面加一个字母啊？

学习学习

[codolio]

恩，学习啦。根据以前的习惯，我会选择用FileWriter的，外层再包一层BufferedWriter，呵呵。

[walkman_22]

为什么要用RandomAccessFile？只是个习惯？

InputStream is = new InputStream("C:XX.txt");
DataInputStream dis = new DataInputStream(is);
System.out.println(dis.readUTF());
s.close();
dis.close();
