使用Arrays.copyOf()方法:Arrays类提供了copyOf()方法,可以用于复制数组。该方法需要指定源数组和要复制的长度,返回一个新的数组。 代码语言:java 复制 targetArray = Arrays.copyOf(sourceArray, sourceArray.length); 这些方法适用于复制对象数组,可以将原始数组中的对象引用复制到新数组中。需要注意的是,这些...

You are just copying a list of references (assuming this is an array of objects). If you want to make a deep copy, you need to use new to create a new instance of each object in the array. Share Improve this answer Follow answered Oct 16, 2010 at 1:19 Justin Ethier 134k5252...

需要注意的是,进行深复制可能会涉及到对象的引用关系和嵌套关系。在复制过程中,需要确保所有相关的对象都可以正确地进行复制,以避免出现引用共享或嵌套对象复制不完整的情况。 希望本文对你理解 Java Map 的深复制有所帮助。感谢阅读! 6. 参考文献 [How to make a deep copy of Java HashMap?](...
