如果我理解正确，您希望保护这些变量，以便它们不能被设置为无效值。所以 Hour 应该只能在 0 到 23 之间，而 minute 应该只能在 0 到 59 之间。
public class Time {
private int Hour;
private int minute;
public int getHour() {
return this.Hour;
}
public int getMinute() {
return this.minute;
}
public void setHour(int hour) {
// this.Hour = Math.min(Math.max(0, hour), 23);
this.Hour = hour > 23 ? 23 : hour < 0 ? 0 : hour;
}
public void setMinute(int minute) {
// this.minute = Math.min(Math.max(0, minute), 59);
this.minute = minute > 59 ? 59 : minute < 0 ? 0 : minute;
}
}
英文:
If I am understanding this correctly. You want to guard the variables so they cannot be set to invalid values. So Hour should only be between 0 and 23, and minute between 0 and 59.
public class Time {
private int Hour;
private int minute;
public int getHour() {
return this.Hour;
}
public int getMinute() {
return this.minute;
}
public void setHour(int hour) {
// this.Hour = Math.min(Math.max(0, hour), 23);
this.Hour = hour > 23 ? 23 : hour < 0 ? 0 : hour;
}
public void setMinute(int minute) {
// this.minute = Math.min(Math.max(0, minute), 59);
this.minute = minute > 59 ? 59 : minute < 0 ? 0 : minute;
}
}

如果您不希望使用数学，那么您可以在您的函数中添加简单的条件。
private int hour;
private int minute;
public void setHour(int value) {
if (value > 23) {
value = 23;
}
if (value < 0) {
value = 0;
}
this.hour = value;
}
public void setMinute(int value) {
if (value > 59) {
value = 59;
}
if (value < 0) {
value = 0;
}
this.minute = value;
}
英文:
If you don't wish to use Math then you can add simple condition into your function.
private int hour;
private int minute;
public void setHour(int value) {
if (value > 23) {
value = 23;
}
if (value < 0) {
value = 0;
}
this.hour = value;
}
public void setMinute(int value) {
if (value > 59) {
value = 59;
}
if (value < 0) {
value = 0;
}
this.minute = value;
}
