Java的clone就是个坑？浅拷贝坑哭你，new才是真香

于Java里头, Clone方法给用于去创建出一个对象的副本。而要是想要使用Clone方法的话, 那就得满足下面这两个条件才行。达成接口, 乃为一个予以标记的接口, 意味着此别类能够被实施克隆, 当中需要于描述类的部分进行补充添加。public class MyClass implements Cloneable { // 类的定义 }复刻clone方法: 于类里把clone方法再度编写, 以此返回一个克隆而成的对象, 在再度构建clone方法之际, 要借助super.clone() 将类的clone方法予以调用。public class MyClass implements Cloneable { // 类的定义 Override public Object clone() throws CloneNotSupportedException { return super.clone(); } }要使用clone方法, 那么能够借助调用克隆对象的clone方法, 以此来创建出一个新的副本对象。MyClass obj1 new MyClass(); MyClass obj2 (MyClass) obj1.clone();要留意的是, clone方法属于浅拷贝, 也就是仅仅复制对象的引用, 并非复制对象的内容倘若想要达成深拷贝, 也就是复制对象的内容, 能够在clone方法里针对对象的属性进行逐个逐一复制, 会在对对象, 对象的属性进行逐个复制。WWw.Share.01km.cN/Article/details/58689.sHtMLWWw.Share.01km.cN/Article/details/49321.sHtMLWWw.Share.01km.cN/Article/details/31601.sHtMLWWw.Share.01km.cN/Article/details/37255.sHtMLWWw.Share.01km.cN/Article/details/16272.sHtMLWWw.Share.01km.cN/Article/details/22787.sHtMLWWw.Share.01km.cN/Article/details/31051.sHtMLWWw.Share.01km.cN/Article/details/25382.sHtMLWWw.Share.01km.cN/Article/details/21352.sHtMLWWw.Share.01km.cN/Article/details/82114.sHtMLWWw.Share.01km.cN/Article/details/84716.sHtMLWWw.Share.01km.cN/Article/details/98388.sHtMLWWw.Share.01km.cN/Article/details/13782.sHtMLWWw.Share.01km.cN/Article/details/34870.sHtMLWWw.Share.01km.cN/Article/details/74308.sHtMLWWw.Share.01km.cN/Article/details/03349.sHtMLWWw.Share.01km.cN/Article/details/07748.sHtMLWWw.Share.01km.cN/Article/details/96676.sHtMLWWw.Share.01km.cN/Article/details/96224.sHtMLWWw.Share.01km.cN/Article/details/01448.sHtMLWWw.Share.01km.cN/Article/details/78822.sHtMLWWw.Share.01km.cN/Article/details/46476.sHtMLWWw.Share.01km.cN/Article/details/56567.sHtMLWWw.Share.01km.cN/Article/details/70988.sHtMLWWw.Share.01km.cN/Article/details/25502.sHtMLWWw.Share.01km.cN/Article/details/21973.sHtMLWWw.Share.01km.cN/Article/details/63303.sHtMLWWw.Share.01km.cN/Article/details/45132.sHtMLWWw.Share.01km.cN/Article/details/56797.sHtMLWWw.Share.01km.cN/Article/details/51157.sHtMLWWw.Share.01km.cN/Article/details/16394.sHtMLWWw.Share.01km.cN/Article/details/62811.sHtMLWWw.Share.01km.cN/Article/details/65240.sHtMLWWw.Share.01km.cN/Article/details/07063.sHtMLWWw.Share.01km.cN/Article/details/77618.sHtMLWWw.Share.01km.cN/Article/details/16815.sHtMLWWw.Share.01km.cN/Article/details/92856.sHtMLWWw.Share.01km.cN/Article/details/52269.sHtMLWWw.Share.01km.cN/Article/details/50827.sHtMLWWw.Share.01km.cN/Article/details/55013.sHtMLWWw.Share.01km.cN/Article/details/80429.sHtMLWWw.Share.01km.cN/Article/details/18118.sHtMLWWw.Share.01km.cN/Article/details/11496.sHtMLWWw.Share.01km.cN/Article/details/15567.sHtMLWWw.Share.01km.cN/Article/details/18979.sHtMLWWw.Share.01km.cN/Article/details/66414.sHtMLWWw.Share.01km.cN/Article/details/53833.sHtMLWWw.Share.01km.cN/Article/details/28354.sHtMLWWw.Share.01km.cN/Article/details/10877.sHtMLWWw.Share.01km.cN/Article/details/48128.sHtMLWWw.Share.01km.cN/Article/details/88365.sHtMLWWw.Share.01km.cN/Article/details/75839.sHtMLWWw.Share.01km.cN/Article/details/07381.sHtMLWWw.Share.01km.cN/Article/details/20085.sHtMLWWw.Share.01km.cN/Article/details/04234.sHtMLWWw.Share.01km.cN/Article/details/19570.sHtMLWWw.Share.01km.cN/Article/details/58297.sHtMLWWw.Share.01km.cN/Article/details/13147.sHtMLWWw.Share.01km.cN/Article/details/29019.sHtMLWWw.Share.01km.cN/Article/details/56779.sHtMLWWw.Share.01km.cN/Article/details/03607.sHtMLWWw.Share.01km.cN/Article/details/92632.sHtMLWWw.Share.01km.cN/Article/details/57448.sHtMLWWw.Share.01km.cN/Article/details/53673.sHtMLWWw.Share.01km.cN/Article/details/87972.sHtMLWWw.Share.01km.cN/Article/details/57275.sHtMLWWw.Share.01km.cN/Article/details/71686.sHtMLWWw.Share.01km.cN/Article/details/45636.sHtMLWWw.Share.01km.cN/Article/details/11497.sHtMLWWw.Share.01km.cN/Article/details/99623.sHtMLWWw.Share.01km.cN/Article/details/59486.sHtMLWWw.Share.01km.cN/Article/details/14949.sHtMLWWw.Share.01km.cN/Article/details/70615.sHtMLWWw.Share.01km.cN/Article/details/48593.sHtMLWWw.Share.01km.cN/Article/details/53596.sHtMLWWw.Share.01km.cN/Article/details/62572.sHtMLWWw.Share.01km.cN/Article/details/81224.sHtMLWWw.Share.01km.cN/Article/details/01120.sHtMLWWw.Share.01km.cN/Article/details/39277.sHtMLWWw.Share.01km.cN/Article/details/20637.sHtMLWWw.Share.01km.cN/Article/details/94013.sHtMLWWw.Share.01km.cN/Article/details/28885.sHtMLWWw.Share.01km.cN/Article/details/57235.sHtMLWWw.Share.01km.cN/Article/details/04071.sHtMLWWw.Share.01km.cN/Article/details/81186.sHtMLWWw.Share.01km.cN/Article/details/82907.sHtMLWWw.Share.01km.cN/Article/details/07916.sHtMLWWw.Share.01km.cN/Article/details/28316.sHtMLWWw.Share.01km.cN/Article/details/46159.sHtMLWWw.Share.01km.cN/Article/details/00419.sHtMLWWw.Share.01km.cN/Article/details/13129.sHtMLWWw.Share.01km.cN/Article/details/60252.sHtMLWWw.Share.01km.cN/Article/details/80857.sHtMLWWw.Share.01km.cN/Article/details/32683.sHtMLWWw.Share.01km.cN/Article/details/84907.sHtMLWWw.Share.01km.cN/Article/details/37845.sHtMLWWw.Share.01km.cN/Article/details/76686.sHtMLWWw.Share.01km.cN/Article/details/37165.sHtMLWWw.Share.01km.cN/Article/details/64671.sHtMLWWw.Share.01km.cN/Article/details/17751.sHtMLWWw.Share.01km.cN/Article/details/62680.sHtMLWWw.Share.01km.cN/Article/details/87860.sHtMLWWw.Share.01km.cN/Article/details/65463.sHtMLWWw.Share.01km.cN/Article/details/75224.sHtMLWWw.Share.01km.cN/Article/details/24937.sHtMLWWw.Share.01km.cN/Article/details/30382.sHtMLWWw.Share.01km.cN/Article/details/39823.sHtMLWWw.Share.01km.cN/Article/details/76164.sHtMLWWw.Share.01km.cN/Article/details/57973.sHtMLWWw.Share.01km.cN/Article/details/98358.sHtMLWWw.Share.01km.cN/Article/details/6364
