/*
Compare Two Java double Arrays Example
This java example shows how to compare two double arrays for equality using
Arrays.equals method.
*/
import java.util.Arrays;
public class CompareDoubleArraysExample {
public static void main(String[] args) {
//create double arrays
double[] dblArray1 = new double[]{10.3221,789.23,427.213};
double[] dblArray2 = new double[]{10.3221,789.23,427.213};
/*
To compare two double arrays use,
static boolean equals(double array1[], double array2[]) method of Arrays class.
It returns true if both arrays are equal. Arrays are considered as equal
if they contain same elements in same order.
Two double elements are considered as equal if
new Double(d1).equals(new Double(d2))
*/
boolean blnResult = Arrays.equals(dblArray1,dblArray2);
System.out.println("Are two double arrays equal ? : " + blnResult);
/*
Please note that two double array references pointing to null are
considered as equal.
Also, two NaN values are considerd equal. But 0.0d and -0.0d are
considered as unequal.
*/
}
}
/*
Output of the program would be
Are two double arrays equal ? : true
*/
