Java int Array
Java int array is used to store int data type values only. The default value of the elements in a int array is false.
With the following Java int array examples you can learn
- how to declare Java int array
- how to assign values to Java int array
- how to get values from Java int array
Initializing a int Array in Java
Arrays are declared with  (square brackets). If you put  (square brackets) after any variable of any type only that variable is of type array remaining variables in that declaration are not array variables those are normal variables of that type.
If you put  (square brackets) after any data type all the variables in that declaration are array variables. All the elements in the array are accessed with index. The array element index is starting from 0 to n-1 number i.e. if the array has 5 elements then starting index is 0 and ending index is 4.
// declares an array of ints
What is the Length of an Array in Java ?
In Java all the arrays are indexed and declared by int only. That is the size of an array must be specified by an int value and not long or short. All the arrays index beginning from 0 to ends at 2147483646. You can store elements upto 2147483647. If you try to store long (big) elements in array, you will get performance problems. If you overcome performance problems you should go to java collections framework or simply use Vector.
