object轉bigdecimal

object轉bigdecimal的具體步驟是什么呢、一起來看下吧：

用Map

對象轉換成Bigdecimal的代碼如下：

import?java.math.BigDecimal;??
import?java.math.BigInteger;??
??
public?class?MathUtils?{??
??????
????public?static?BigDecimal?getBigDecimal(?Object?value?)?{??
????????BigDecimal?ret?=?null;??
????????if(?value?!=?null?)?{??
????????????if(?value?instanceof?BigDecimal?)?{??
????????????????ret?=?(BigDecimal)?value;??
????????????}?else?if(?value?instanceof?String?)?{??
????????????????ret?=?new?BigDecimal(?(String)?value?);??
????????????}?else?if(?value?instanceof?BigInteger?)?{??
????????????????ret?=?new?BigDecimal(?(BigInteger)?value?);??
????????????}?else?if(?value?instanceof?Number?)?{??
????????????????ret?=?new?BigDecimal(?((Number)value).doubleValue()?);??
????????????}?else?{??
????????????????throw?new?ClassCastException("Not?possible?to?coerce?["+value+"]?from?class?"+value.getClass()+"?into?a?BigDecimal.");??
????????????}??
????????}??
????????return?ret;??
????}??
}
