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...

return "Value of i :" + i; } } Note*: If you want to create Object in this way class needs to have public default Constructor. Using Clone We can also use Clone() method to create a copy of an existing Object. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ...
