Next, create another variable, student2, and assign it with the value of student2.let student1 = {name: 'kevin'} let student2 = student1 Here, we just made a shallow copy of the student1 object. Now, let’s try to change the value of the name property to something else from ...

deep copy java # 深拷贝与浅拷贝:Java中的思考 在Java编程中,我们经常需要处理对象的复制。对象复制有两种主要方式:浅拷贝(Shallow Copy)和深拷贝(Deep Copy)。在本文中,我们将重点讨论深拷贝,通过示例和图表来更好地理解这一概念。 ## 什么是拷贝 拷贝是指创建一个对象的另一个实例。在Java中,由于对象的引...

Recall array variables in Java are references or pointers. A shallow copy can be made by simply copying the reference. public class Ex{ private int[] data; public Ex(int[] values){ data = values; } public void showData(){ System.out.println( Arrays.toString(data) ); ...
usejava.io.PipedInputStreamandjava.io.PipedOutputStreamto serialize the object in one thread and simultaneously deserialize it in another thread. This technique is more complex, but allows the two halves of the operation to coordinate using a small buffer rather than a large byte array. Figure 1...

For deep cloning, we have to first serialize and then perform deserialization. For serialization, we have usedByteArrayOutputStreamandObjectOutputStream.
