Java如何写入文件？

解决方法

此示例演示如何使用BufferedWriter类的write方法写入文件。

import java.io.*;

public class Main {
   public static void main(String[] args)  {
      try {
         BufferedWriter out = new 
         BufferedWriter(new FileWriter("outfilename"));
         out.write("aString");
         out.close();
         System.out.println
         ("File created successfully");
      }
      catch (IOException e) {
      }
   }
}

结果

上面的代码示例将产生以下结果。

File created successfully.
