There is no difference, other than that declarations in C++ can also initialise the variable in a single instruction.
C example:
int x; // declaration
x=5; // initialisation
C++ example:
int y=5; // declaration and initialisation combined.

∙ 10y agoConsider the following:
C++:
int* anArray;
anArray = new int[10];
delete[]anArray;
Java:
int[] anArray;
anArray = new int[10];
The only real difference is the type used to refer to the array. In C++, we use a primitive int pointer, but in Java, we use an int array reference. Note that all integrals are implemented as objects in Java, since there is no concept of a primitive. All this really means is that C++ programmers must return the memory back to the system whereas Java's garbage collection takes care of it for us.

Create an array of 10 elements in java?
to create a new Java array use typeName[] arrayName = new typeName[10]; This gives an array with 10 elements. To set the elements you can use arrayName[index] = value; Remember that the index number starts at 0, so the array will only go to index 9. You can also declare the contents when the array is created typeName[] arrayName = {value1, vaue2, ...} The values used in the array must be objects. In java 5+ you can use primitive types with no concern due to auto-boxing.
