How to Declare an Integer Array in Java - Step by Step Examples
How to Declare an Integer Array in Java ?
Answer
To declare an integer array in Java, you can use array initialization syntax or the new
keyword with the array type.
✐ Examples
1 Declare and Initialize an Integer Array
In this example,
- We declare an integer array named
numbers
with predefined values. - We initialize the array using array initialization syntax.
- We print the array to demonstrate the initialization.
Java Program
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
int[] numbers = {1, 2, 3, 4, 5};
System.out.println("Integer Array: " + Arrays.toString(numbers));
}
}
Output
Integer Array: [1, 2, 3, 4, 5]
2 Declare an Empty Integer Array
In this example,
- We declare an empty integer array named
emptyArray
with a specific size. - We print the array to demonstrate the declaration.
Java Program
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
int[] emptyArray = new int[0];
System.out.println("Empty Integer Array: " + Arrays.toString(emptyArray));
}
}
Output
Empty Integer Array: []
