例子

下面的示例演示java.io.BufferedWriter.newLine()方法的用法。

package com.yiibai;

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;
      String s = "Hello World!!";
            
      try{
         // create new string writer
         sw = new StringWriter();
         
         // create new buffered writer
         bw = new BufferedWriter(sw);
         
         // write string sequence to buffered writer
         bw.write(s, 0, 5);
         
         // write new line to the buffered writer
         bw.newLine();
         
         // write the next string sequence to buffered writer
         bw.write(s, 6, s.length()-6);
         
         // releases all bytes to the underlying stream
         bw.flush();

         // print
         System.out.print(sw.getBuffer());
         
      }catch(Exception e){
         
         // if any I/O error occurs
         e.printStackTrace();
      }finally{
         
         // releases system resources from the streams
         if(sw!=null)
            sw.close();
         if(bw!=null)
            bw.close();
      }
   }
}

让我们来编译和运行上面的程序，这将产生以下结果：

Hello
World!!
