> s := "some string"; s := "some string" Java object cloning using copy constructors and defensive copy methods certainly have some advantages but we have to explicitly write some code to achieve deep cloning in all these approaches. The following are the methods of the base Java Object which are present in all Java objects due to the implicit inheritance of Object. Introduction This article is a continuation of a series of articles describing the often forgotten about methods of the Java language's base Object class. The shallow copy is the approach when we only copy field values and therefore the copy might be dependant on the original object. You can also use the copyValueOf() method, which represents the character sequence in the array specified. As soon as you create a second copy of a string that already exists, it get turned into a reference to the first copy. The return value is not an independent copy of this instance; it is simply another view of the same data. The copyValueOf() method returns a String that represents the characters of a char array.. Here, you can specify the part of array to be copied. Let us first create a character array.

The precise meaning of "copy" may depend on the class of the object. Syntax: LinkedList.clone() Parameters: This method does not … Unless an explicit copy of original is needed, use of this constructor is unnecessary since Strings are immutable. In the deep copy approach, we make sure that all the objects in the tree are deeply copied, so the copy isn't dependant on … The Java.util.LinkedList.clone() method is used to create a shallow copy of the mentioned linked list. In Maple, you cannot really copy a string in the sense that there can be two copies of the string in memory. In Java, cloning performs a shallow copy (copies the reference of the original object along with its field values to the new object). Sorry for waking up this thread, but it came up #1 on Google's search results for "Java String clone". This method returns a new String array and copies the characters into it.

In that case, why not intern the String - which essentially does the same thing. It returns another copy of same data. The java.lang.Object.clone() creates and returns a copy of this object.

Copy String. Initializes a newly created String object so that it represents the same sequence of characters as the argument; in other words, the newly created string is a copy of the argument string. Use the Copy or CopyTo method to create a separate String object with the same value as this instance.. Because the Clone method simply returns the existing string instance, there is little reason to call it directly..
