excludeExact(int num1,int num2)
excludeExact(int num1,int num2)是Java中StrictMath類的內置方法,用於獲取給定參數num1和num2的差。如果結果溢出int,則拋出異常。
由於subtractExact(int num1,int num2)是靜態的,因此對象創建不是強製性的。
用法:
public static int subtractExact(int num1, int num2)
參數:該方法接受兩個參數:
- num1:第一個整數值和
- num2:要從第一個整數減去的第二個整數值。
返回值:該方法返回給定參數num1和num2的差。
異常:如果結果溢出一個int,則拋出ArithmeticException。
例子:
Input: num1 = 750, num2 = 50 Output: 700 Input: num1 = 361, num2 = 929 Output: -568
以下示例程序旨在說明java.lang.StrictMath.subtractExact()方法:
示例1:
// Java praogram to illustrate the
// java.lang.StrictMath.subtractExact()
import java.lang.StrictMath;
class Geeks {
// driver code
public static void main(String args[])
{
// Get the int values
// for which the difference is required
int num1 = 76761;
int num2 = 99;
int num3 = 786616;
// Get difference between
// num1 and num2
System.out.println("Difference of " + num1
+ " and " + num2 + " = "
+ StrictMath
.subtractExact(num1, num2));
// Get difference between
// num1 and num3
System.out.println("Difference of " + num1
+ " and " + num3 + " = "
+ StrictMath
.subtractExact(num1, num3));
}
}
輸出:
Difference of 76761 and 99 = 76662 Difference of 76761 and 786616 = -709855
excludeExact(long num1,long num2)
excludeExact(long num1,long num2)是Java中StrictMath類的內置方法,用於獲取給定參數num1和num2的差。如果結果長時間溢出,則會引發異常。由於subtractExact(long num1,long num2)是靜態的,因此對象創建不是強製性的。
用法:
public static long subtractExact(long num1, long num2)
參數:該方法接受兩個參數:
- num1:第一個long值和
- num2:要從第一個減去的第二個long值。
返回值:該方法返回給定參數num1和num2的差。
異常:如果結果長時間溢出,則拋出ArithmeticException。
例子:
Input: num1 = 750, num2 = 50 Output: 700 Input: num1 = 361, num2 = 929 Output: -568
以下示例程序旨在說明java.lang.StrictMath.subtractExact()方法:
示例1:
// Java praogram to illustrate the
// java.lang.StrictMath.subtractExact()
import java.lang.StrictMath;
class Geeks {
// driver code
public static void main(String args[])
{
// Get the long values
// for which the difference is required
long num1 = -76342561;
long num2 = 949;
long num3 = 78326616;
// Get difference between
// num1 and num2
System.out.println("Difference of " + num1
+ " and " + num2 + " = "
+ StrictMath
.subtractExact(num1, num2));
// Get difference between
// num1 and num3
System.out.println("Difference of " + num1
+ " and " + num3 + " = "
+ StrictMath
.subtractExact(num1, num3));
}
}
輸出:
Difference of -76342561 and 949 = -76343510 Difference of -76342561 and 78326616 = -154669177
