Declaring an array
Syntax: One Dimensional Array
|Method 1||Type arrayReferenceName; //Recommended|
|Method 2||Type arrayReferenceName; //Legal, but not recommended|
|Method 1||Type  arrayReferenceName; //Recommended|
|Method 2||Type arrayReferenceName ; //Legal, but not recommended|
Type can be either primitive or reference.
|Primitive Array||Reference Array|
| int numbers;|
int  numbers;
| String studentNames;|
String  strings;
You declare an array by specifying the type of the element it will hold followed by square bracket then array reference name.
This allows better readability and anyone reading the code can easily tell that studentGrades is a reference to a char array object and not a char primitive.
You declare an array by specifying the type of the element it will hold followed by square bracket to the right of the array reference name.
char studentGrades; or char studentGrades ; String strings; //two dimensional array. Legal but not recommended.
This is legal declaration but less readable. Space between array reference name and  is legal but bad.
- An array of type int (int) says that each element is of type int, i.e.) each element is just a int variable. Similarly, an array of type Person (Person) specifies that each element it can hold is of type Person.
- You can also declare an array by assigning default null value.
int numbers = null;
