How do I declare and initialize an array in Java?

Question

I want to declare and initialize an array in JAVA, how can I do that?

Answer 1

To declare your array either use this syntax:

<elementType>[] <arrayName>;

or use this one:

<elementType> <arrayName>[];

Example:

int intArray[];

//intArray will store some integer value

int []intArray;

To Initialize your array, use this for primitive types:

int[] myIntArray = new int[4];

int[] myIntArray = {2, 3, 4};

int[] myIntArray = new int[]{2, 3, 4};

for strings replace int by a string in the above code:

String[] myStringArray = new String[4];

String[] myStringArray = {"q", "w", "e"};

String[] myStringArray = new String[]{"q", "w", "e"};

In case you want to declare the array first and then initialize it:

String[] myStringArray;

myStringArray = new String[]{"q", "w", "e"};
