When we want to copy an object in Java, there are two possibilities that we need to consider,a shallow copy and a deep copy. For the shallow copy approach, we only copy field values, therefore the copy might be dependant on the original object. In the deep copy approach, we make sure...
Write a Java program to convert an ArrayList to an array.Pictorial Presentation:Sample Solution:Java Code :// Import the ArrayList and Arrays classes from the Java utility library. import java.util.ArrayList; import java.util.Arrays; // Define a class named Exercise21. public class Exercise21 ...
Options files control which compiler to use, the compiler and link command options, and the runtime libraries to link against. Using the 'mex -setup' command selects an options file that is placed in ~/.matlab/R2012a and used by default for 'mex'. An options file in the current workin...

can make a deep copy of an object by using the Cloneable() interface and overriding the clone() method. Copy constructors are an easier and more flexible way of performing a deep copy. We can also use Serialization but we need to remember that its computation is expensive than other ...
If scientists can clone sheep, it should be expected that you could clone a Java array! From a coding perspective, making a copy of an array in Java is really not much harder than Ctrl + C and Ctrl + V in Microsoft Word. OK, it might take a little more effort, but the concept is...
