实例

以下示例显示了java.io.BufferedWriter.write(int c)方法的用法。

package com.tutorialspoint;

  import java.io.BufferedWriter;
  import java.io.IOException;
  import java.io.StringWriter;

  public class BufferedWriterDemo {
     public static void main(String[] args) throws IOException {

        StringWriter sw = null;
        BufferedWriter bw = null;

        try{
           // create string writer
           sw = new StringWriter();

           //create buffered writer
           bw = new BufferedWriter(sw);

           // integer range represents alphabets in uppercase
           for(int i = 65; i<=90; i++)
           {
              bw.write(i);
           }

           // forces out the characters to string writer
           bw.flush();

           // string buffer is created
           StringBuffer sb = sw.getBuffer();

           // prints the string
           System.out.println(sb);

        }catch(IOException e){
           // if I/O error occurs
           e.printStackTrace();
        }finally{
           // releases any system resources associated with the stream
           if(sw!=null)
              sw.close();
           if(bw!=null)
              bw.close();
        }
     }
  }

让我们编译并运行上面的程序,这将产生以下结果:
