java定义一个电话手表类要求要有显示当前时间功能,打电话功能,定位功能和测试类

以下是一个可能的Java定义:
```
public class PhoneWatch {
private String time;
private boolean calling;
private String location;
public PhoneWatch() {
setTime("00:00");
setCalling(false);
setLocation("");
}
public void setTime(String time) {
this.time = time;
}
public String getTime() {
return time;
}
public void setCalling(boolean calling) {
this.calling = calling;
}
public boolean isCalling() {
return calling;
}
public void setLocation(String location) {
this.location = location;
}
public String getLocation() {
return location;
}
public void makeCall(String number) {
System.out.println("Dialing " + number + "...");
setCalling(true);
// call implementation
}
public void hangUp() {
System.out.println("Hanging up...");
setCalling(false);
// hang up implementation
}
public void locate() {
System.out.println("Locating...");
// location implementation
setLocation("123.4567,89.0123");
}
}
public class PhoneWatchTester {
public static void main(String[] args) {
PhoneWatch watch = new PhoneWatch();
watch.setTime("12:34");
System.out.println("Time: " + watch.getTime());
watch.makeCall("1234567890");
System.out.println("Is calling: " + watch.isCalling());
watch.locate();
System.out.println("Location: " + watch.getLocation());
watch.hangUp();
System.out.println("Is calling: " + watch.isCalling());
}
}
```
在这个例子中,`PhoneWatch` 类有三个属性:当前时间 `time`、是否正在通话 `calling` 和位置信息 `location`。它有三个方法:设置当前时间 `setTime`、获取当前时间 `getTime`、拨打电话 `makeCall`、挂断电话 `hangUp`、定位 `locate`。`PhoneWatchTester` 类是一个测试类,它创建一个 `PhoneWatch` 实例并使用其方法来显示当前时间、拨打电话、定位和挂断电话。
请注意,这只是一个简单的示例,实际上一个电话手表可能需要更多的属性和方法来实现其所有功能。
