Check two float arrays for equality in Java
To check two float arrays for equality, use the Arrays.equals() method.
In our example, we have the following two float arrays.
float[] floatVal1 = new float[] { 3.2f, 5.5f, 5.3f };
float[] floatVal2 = new float[] { 3.2f, 5.5f, 5.3f };Let us now compare them for equality.
if (Arrays.equals(floatVal1, floatVal2)) {
System.out.println("Both are equal!");
}The following is an example wherein we compare arrays and with that also use == to check for other conditions.
Example
import java.util.Arrays;
public class Demo {
public static void main(String args[]) {
float[] floatVal1 = new float[] { 3.2f, 5.5f, 5.3f };
float[] floatVal2 = new float[] { 3.2f, 5.5f, 5.3f };
if (floatVal1 == null) {
System.out.println("First array is null!");
}
if (floatVal2 == null) {
System.out.println("Second array is null!");
}
if (floatVal1.length != floatVal2.length) {
System.out.println("Both does not have equal number of elements!");
}
if (Arrays.equals(floatVal1, floatVal2)) {
System.out.println("Both are equal!");
}
}
}Output
Both are equal!
