示例

下面的例子展示了 java.io.CharArrayWriter.writeTo(Writer out) 方法的用法。

package com.tutorialspoint;

import java.io.CharArrayWriter;

public class CharArrayWriterDemo {
   public static void main(String[] args) {      
      String str = "Hello World!!";
      CharArrayWriter chw = null;
      CharArrayWriter chwd = null;   
      
      try {
         // create character array writer
         chw = new CharArrayWriter();

         // create destination character array writer
         chwd = new CharArrayWriter();
         
         // string to be written to writer
         chw.write(str);
         
         // write to destination array writer
         chw.writeTo(chwd);
         
         // print the destination buffer content as string
         System.out.println(chwd.toString());
               
      } catch(Exception e) {
         // for any error
         e.printStackTrace();
      } finally {
         // releases all system resources from writer
         if(chw!=null)
            chw.close();
      }
   }
}

让我们编译并运行上面的程序，这将产生以下结果 -
