Java: Find the angle between the hour and minute hands
Angle Between Clock Hands
Write a Java program to find the angle between the hour and minute hands.
Sample Solution:
Java Code:
import java.util.*;
public class solution {
static int calcAngle(double ha, double ma) {
if (ha == 12)
ha = 0;
if (ma == 60)
ma = 0;
int hour_angle = (int)(0.5 * (ha * 60 + ma));
int minute_angle = (int)(6 * ma);
int angle = Math.abs(hour_angle - minute_angle);
angle = Math.min(360 - angle, angle);
return angle;
}
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.print("Input angles move by hour hand: ");
int ha = scan.nextInt();
System.out.print("Input angles move by minute hand: ");
int ma = scan.nextInt();
if (ha < 0 || ma < 0 || ha > 12 || ma > 60) {
System.out.println("Wrong input..!");
} else {
System.out.println("Angle between hour and minute hands " + calcAngle(ha, ma) + " degree.");
}
}
}
Sample Output:
Input angles move by hour hand: 5 Input angles move by minute hand: 15 Angle between hour and minute hands 67 degree.
