Answer Izzzz – > Are there copy constructor and assignment > constructor in java? > There is such a thing as a copy constructor in Java, but it does not play the special role that such constructors do in C++. A copy constructor in Java is just like any other constructor: you call it with new. public class A { private int x; public A(int x) { this.x = v; } public A(A that) { this.x = that.x; } } … A a1 = new A(5); A a2; a2 = new A(a1); … There are no assignment constructors, or anything much like them, in Java. That is because Java does not have operator overloading. The assignment operation (=) is always a shallow assignment, or scalar assignment if you prefer, and you NEVER have to doubt that. I’ve gotten in plenty of trouble with C++ code that used fancy copy constructors and overloaded assignment operators! Java does have the notion of a clone (copy) method. Any object can support the clone() method; by convention the method implementation is supposed to perform a deep copy of t
