3.2. Deep Copying a Java Collections Creating a deep copy of a collection is rather easy. We need to create a new instance of collection and copy all elements from the given collection into the cloned collection
We suggest usingin-memory deep cloningwhenever it is the only need and we don’t need to persist the object for future use. In this Java deep cloning example, we will suggest one mechanism of in-memory deep cloning for our reference. Please remember that deep cloning is evil forsingleton ...
However, cloning an object using serialization comes with some performance overhead and we can improve on it by usingin-memory serializationif we just need to clone the object and don’t need to persist it in a file for future use. We will use belowEmployeeclass as an example which hasnam...
Here is an example of its usage: Clonercloner=newCloner();MyClassclone=cloner.deepClone(o);// clone is a deep-clone of o IMPORTANT: deep cloning of Java classes might mean thousands of objects are cloned! Also cloning of files and streams might make the JVM crash. Enable dumping of clo...
In above example we see cloning of one dimensional array, where aic has a cloned array or a separate copy of ai after executing aic = ai.clone(); statement. Cloning could be a feasible solution in case of one dimensional arrays of basic types or objects that have only primitive types as...
Let’s perform the cloning.For example, consider the student1 object above that contains the value kevin for the name property. Next, use the structuredClone() method and supply the student1 object as its parameter.Finally, assign the method to a variable student2. This makes the student2 ...
