Question

Solve it by JAVA please.

DO NOT IMPORT PLEASE.

THANKS

Method 10:
public static double nearestNeighbor(double v, double[] values)

Return the value of the nearest neighbor to v. If v is some value, look through the list of values to find the one which is closest in value to v. For example, if v = 1.2 and the input array is {3.2, 1.7, 2.4, 0.9, 4.4}, then the method will return 0.9 because it is the value closest to 1.2 in the list. If there is a tie (for example, both 0.9 and 1.5 are the same distance to 1.2), then return the one which occurs first in the list. If the list is empty, then return v.

public static double nearestNeighbor(double v, double[] values) {
    double result = values[0], d1, d2;
    for (int i = 0; i < values.length; i++) {
        d1 = Math.abs(values[i] - v);
        d2 = Math.abs(result - v);
        if(d1 < d2) {
            result = values[i];
        }
    }
    return result;
}
