How to check if an Array is Not Empty in Java - Step by Step Examples
How to check if an Array is Not Empty in Java ?
Answer
To check if an array is not empty in Java, you can compare its length with 0.
✐ Examples
1 Check if Given Array with Elements is Not Empty
In this example,
- We create an array named
numbers
with some elements. - We check if the array is not empty by comparing its length with 0 and store the result in the variable
notEmpty
. - Finally, we print whether the array is not empty or not.
Java Program
public class Main {
public static void main(String[] args) {
int[] numbers = {1, 2, 3};
boolean notEmpty = numbers.length != 0;
System.out.println("Array is not empty: " + notEmpty);
}
}
Output
Array is not empty: true
2 Check if Empty Array is Not Empty
In this example,
- We create an empty array named
emptyArray
. - We check if the array is not empty by comparing its length with 0 and store the result in the variable
notEmpty
. - Finally, we print whether the array is not empty or not.
Java Program
public class Main {
public static void main(String[] args) {
int[] emptyArray = new int[0];
boolean notEmpty = emptyArray.length != 0;
System.out.println("Array is not empty: " + notEmpty);
}
}
Output
Array is not empty: false
