How to Declare a Float Array in Java ?

Answer

To declare a float array in Java, you can specify the type as float and initialize it with the desired values.

✐ Examples

1 Declare and Initialize Float Array

In this example,

We declare a float array named floatArray and specify its size.
We initialize the elements of the array with float values enclosed in curly braces.
Optionally, we can also declare and initialize the array in one line.
Finally, we print the array elements to standard output.

Java Program

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        float[] floatArray = new float[3]; // Declare float array with size 3
        floatArray[0] = 1.5f; // Initialize element at index 0
        floatArray[1] = 2.8f; // Initialize element at index 1
        floatArray[2] = 3.2f; // Initialize element at index 2

        // Alternatively, declare and initialize in one line
        float[] anotherFloatArray = {1.5f, 2.8f, 3.2f};

        System.out.println("Float Array: " + Arrays.toString(floatArray));
        System.out.println("Another Float Array: " + Arrays.toString(anotherFloatArray));
    }
}

Output

Float Array: [1.5, 2.8, 3.2]
Another Float Array: [1.5, 2.8, 3.2]
