Java示例使用emit（）缓冲字符串

public class StringBuffer {

   public static void main(String[] args) {

      countTo_N_Improved();

   }

   private final static int MAX_LENGTH = 30;

   private static String buffer = "";



   private static void emit(String nextChunk) {

      if(buffer.length() + nextChunk.length() > MAX_LENGTH) {

         System.out.println(buffer);

         buffer = "";  

      }

      buffer += nextChunk;

   }

   private static final int N = 100;

   private static void countTo_N_Improved() {

      for (int count = 2; count<= N; count = count+2) {

         emit(" " + count);

      }

   }

}
