double[][]转为String字符串
有如下的double[][]
double[][]   doubleArray={{1,2,3,4,5},{11,22,33,44,55},[111,222,333,444,555].....}
现在想把以上的double[][]转为以下格式的字符串   1,11,111;2,22,222;3,33,333;4,44,444;5,55,555;

请高手帮帮忙。。谢谢了

public static void main(String[] args) {
  double[][] doubleArray={{1,2,3,4,5},{11,22,33,44,55},{111,222,333,444,555}};
  StringBuffer sb = new StringBuffer();
  for(int i=0; i <doubleArray[0].length; i++){
    for(int j=0; j <doubleArray.length; j++){
      sb.append(String.format( "%.0f ", doubleArray[j][i]));
      if(j <doubleArray.length-1) {
        sb.append( ", ");
      }
    }
    sb.append( "; ");
  }
  System.out.println(sb.toString());
}
