私は時計アプレットを作っていて、ほぼ完成していますが、まだやらなければならないことが 1 つあります。秒針が動くたびに時計を「カチカチ」させたいのですが、「カチカチ」音のコードをどこに置くかわかりません。アプレットのコードは次のとおりです。
import java.applet.*;
import java.awt.*;
import java.util.*;
import java.net.URL;
import java.text.*;
public class ClockApplet extends Applet implements Runnable {
Ellipse2D line1 = new Ellipse2D.Float(100, 150, 200, 200);
int width, height;
Thread t = null;
boolean threadSuspended;
int hours = 0, minutes = 0, seconds = 0;
String timeString = "";
public void init() {
width = getSize().width;
height = getSize().height;
setBackground(Color.white);
}
public void start() {
if (t == null) {
t = new Thread(this);
t.setPriority(Thread.MIN_PRIORITY);
threadSuspended = false;
t.start();
} else {
if (threadSuspended) {
threadSuspended = false;
synchronized (this) {
notify();
}
}
}
}
public void stop() {
threadSuspended = true;
}
public void run() {
try {
while (true) {
// Here's where the thread does some work:
Calendar cal = Calendar.getInstance();
hours = cal.get(Calendar.HOUR_OF_DAY);
if (hours > 12)
hours -= 12;
minutes = cal.get(Calendar.MINUTE);
seconds = cal.get(Calendar.SECOND);
SimpleDateFormat formatter = new SimpleDateFormat("hh:mm:ss",
Locale.getDefault());
Date date = cal.getTime();
timeString = formatter.format(date);
// Now the thread checks to see if it should suspend itself
if (threadSuspended) {
synchronized (this) {
while (threadSuspended) {
wait();
}
}
}
repaint();
t.sleep(1000); // interval given in milliseconds
}
} catch (InterruptedException e) {
}
}
void drawHand(double angle, int radius, Graphics g) {
angle -= 0.5 * Math.PI;
int x = (int) (radius * Math.cos(angle));
int y = (int) (radius * Math.sin(angle));
g.drawLine(width / 2, height / 2, width / 2 + x, height / 2 + y);
}
void drawWedge(double angle, int radius, Graphics g) {
angle -= 0.5 * Math.PI;
int x = (int) (radius * Math.cos(angle));
int y = (int) (radius * Math.sin(angle));
angle += 2 * Math.PI / 3;
int x2 = (int) (5 * Math.cos(angle));
int y2 = (int) (5 * Math.sin(angle));
angle += 2 * Math.PI / 3;
int x3 = (int) (5 * Math.cos(angle));
int y3 = (int) (5 * Math.sin(angle));
g.drawLine(width / 2 + x2, height / 2 + y2, width / 2 + x, height / 2
+ y);
g.drawLine(width / 2 + x3, height / 2 + y3, width / 2 + x, height / 2
+ y);
g.drawLine(width / 2 + x2, height / 2 + y2, width / 2 + x3, height / 2
+ y3);
}
void drawCircle(Graphics g) {
g.drawOval(0, 0, 200, 200);
}
public void paint(Graphics g) {
g.setColor(Color.black);
drawWedge(2 * Math.PI * hours / 12, width / 5, g);
drawWedge(2 * Math.PI * minutes / 60, width / 3, g);
g.setColor(Color.red);
drawHand(2 * Math.PI * seconds / 60, width / 2, g);
g.setColor(Color.black);
g.drawString(timeString + " ET", 10, height - 10);
g.setFont(new Font("Arial", Font.PLAIN, 30));
g.drawString("12", 85, 30);
g.drawString("1", 140, 40);
g.drawString("2", 170, 70);
g.drawString("3", 180, 110);
g.drawString("4", 170, 150);
g.drawString("5", 140, 180);
g.drawString("6", 92, 195);
g.drawString("7", 46, 180);
g.drawString("8", 16, 150);
g.drawString("9", 5, 110);
g.drawString("10", 16, 70);
g.drawString("11", 46, 40);
drawCircle(g);
}
}
そして、これが*カチカチ*音のコードです:
try {
Clip tick = AudioSystem.getClip();
URL clipURL = new URL("file://C:/users/owner/desktop/Tick.wav");
AudioInputStream ais = AudioSystem.getAudioInputStream(clipURL);
tick.open(ais);
tick.start();
} catch (Exception e) {
System.out.println("Error playing sound!");
}
私が知る必要があるのは、サウンド コードをアプレット コードのどこに置くかだけです。いろいろなところを試してみましたが、うまくいかないようです。
