怎么把String字符串转换成集合

[XiaoYi96]

这是一个String字符串，我想把它转换成MAP，求教怎么写后台代码，包括实体类该写啥，经理说必须是在后台转
{"code":"1","table":{
"title" :["单据名称","单据日期", "提交人员", "单据流水","帐套编号","帐套名称", "逻辑表名"],
"value0":["采购请购单","20160124","0034", "86", "005", "演示", "CGQGD"],
"value1":["采购请购单","20160123","0056", "78", "005", "演示", "CGQGD"],
"value2":["采购请购单","20160123","0041" ,"80", "005", "演示", "CGQGD"],
"value3":["采购请购单","20160122","0037", "81", "005", "演示", "CGQGD"],
"value4":["采购请购单","20160122","0052", "82", "005", "演示", "CGQGD"],
"value5":["采购请购单","20160122","0043", "83", "005", "演示", "CGQGD"],
"value6":["采购请购单","20160124","0034", "84", "005", "演示", "CGQGD"],
"value7":["采购请购单","20160126","0054", "88", "005", "演示", "CGQGD"]}}

文件内容复制到file.bin文件中.要不需要转义太多的双引号了.

[快叫我java小菜鸟]

不能把数据组织成json标准格式么，用字符串处理多麻烦，下次万一不一样了呢

中国程序员的质量真是让人担心啊。
