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xy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xy

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
