在 Java 中,設置邊界值通常是為了確保數據在某個范圍內
Math.min()
和 Math.max()
方法:public class BoundaryValueExample {
public static void main(String[] args) {
int value = 10;
int lowerBound = 5;
int upperBound = 8;
int boundedValue = Math.min(Math.max(value, lowerBound), upperBound);
System.out.println("Bounded value: " + boundedValue);
}
}
public class BoundaryValueExample {
public static void main(String[] args) {
int value = 10;
int lowerBound = 5;
int upperBound = 8;
int boundedValue;
if (value< lowerBound) {
boundedValue = lowerBound;
} else if (value > upperBound) {
boundedValue = upperBound;
} else {
boundedValue = value;
}
System.out.println("Bounded value: " + boundedValue);
}
}
public class BoundaryValueExample {
public static void main(String[] args) {
int value = 10;
int lowerBound = 5;
int upperBound = 8;
int boundedValue = boundValue(value, lowerBound, upperBound);
System.out.println("Bounded value: " + boundedValue);
}
private static int boundValue(int value, int lowerBound, int upperBound) {
return Math.min(Math.max(value, lowerBound), upperBound);
}
}
這些示例都將確保 boundedValue
在 lowerBound
和 upperBound
之間。如果 value
小于 lowerBound
,則 boundedValue
將等于 lowerBound
;如果 value
大于 upperBound
,則 boundedValue
將等于 upperBound
;否則,boundedValue
將等于 value
。
