我有这样的 数组：String[][] data ={
{"0001","2","12"},
{"0001","3","13"},
{"0001","3","13"},
{"0002","6","26"},
{"0002","5","25"},
{"0002","5","25"},
};



怎么处理成：

String[][] data ={
{"0001","2+3+3","12+13+13"},

{"0002","6+5+5","26+25+25"},

};

谢谢！

	public static void main(String[] args) {
		String[][] data ={
				{"0001","2","12"},
				{"0001","3","13"},
				{"0001","3","13"},
				{"0002","6","26"},
				{"0002","5","25"},
				{"0002","5","25"},
				}; 
		String[][] result = new String[data.length / 3][3];
		for (int i = 0; i < data.length / 3; i++) {
			int index = i * 3;
			result[i][0] = data[index][0];
			result[i][1] = data[index][1] + "+" +data[index+1][1] + "+" + data[index+2][1];
			result[i][2] = data[index][2] + "+" +data[index+1][2] + "+" + data[index+2][2];
			System.out.println(result[i][0]);
			System.out.println(result[i][1]);
			System.out.println(result[i][2]);
		}
		data = result;
	}
