Java番石榴 | IntMath 类的 mean() 方法
Guava 的 IntMath 类的mean(int x, int y)方法接受两个参数x和y并计算它们的算术平均值,四舍五入到负无穷大。此方法具有溢出弹性。
句法 :
public static int mean(int x, int y)
参数:此方法接受两个整数类型的参数x和y 。
返回值:该方法返回 x 和 y 的算术平均值,向负无穷大舍入。
异常:该方法没有任何异常。
示例 1:
// Java code to show implementation of
// mean(int x, int y) method of Guava's
// IntMath class
import java.math.RoundingMode;
import com.google.common.math.IntMath;
class GFG {
// Driver code
public static void main(String args[])
{
int x = 1542;
int y = 421;
// Using mean(int x, int y)
// method of Guava's IntMath class
int ans = IntMath.mean(x, y);
// Displaying the result
System.out.println("Mean of " + x + " and "
+ y + " is : " + ans);
}
}
输出 :
Mean of 1542 and 421 is : 981
示例 2:
// Java code to show implementation of
// mean(int x, int y) method of Guava's
// IntMath class
import java.math.RoundingMode;
import com.google.common.math.IntMath;
class GFG {
// Driver code
public static void main(String args[])
{
int x = 214;
int y = 154;
// Using mean(int x, int y)
// method of Guava's IntMath class
int ans = IntMath.mean(x, y);
// Displaying the result
System.out.println("Mean of " + x + " and "
+ y + " is : " + ans);
}
}
输出 :
Mean of 214 and 154 is : 184
