The normal interpretation is that a "shallow" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to the same array as in the original; e.g. Example eg2 = new Example(eg1.foo, eg1.bar); The normal interpretation of a "deep" copy of eg1 woul...
使用map()方法将流中的每个元素进行拷贝操作。 使用collect()方法将拷贝后的元素收集到一个新的List中,即深拷贝的结果。 下面是示例代码: importjava.util.ArrayList;importjava.util.List;importjava.util.stream.Collectors;publicclassDeepCopyExample{publicstaticvoid 1. 2. 3. 4. 5....
