Java Guava LongMath mean(long x, long y)用法及代码示例

Guava LongMath类的mean(long x，long y)方法接受两个参数x和y，并计算它们的算术平均值，取整为负无穷大。此方法具有溢出弹性。

用法:

public static long mean(long x, long y)

参数：此方法接受长类型的两个参数x和y。

返回值：该方法返回x和y的算术平均值，四舍五入为负无穷大。

异常：该方法没有任何异常。

范例1：

// Java code to show implementation of 
// mean(long x, long y) method of Guava's 
// LongMath class 
  
import java.math.RoundingMode; 
import com.google.common.math.LongMath; 
  
class GFG { 
  
    // Driver code 
    public static void main(String args[]) 
    { 
        long x = 1542; 
        long y = 421; 
  
        // Using mean(long x, long y) 
        // method of Guava's LongMath class 
        long ans = LongMath.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

范例2：

// Java code to show implementation of 
// mean(long x, long y) method of Guava's 
// LongMath class 
  
import java.math.RoundingMode; 
import com.google.common.math.LongMath; 
  
class GFG { 
  
    // Driver code 
    public static void main(String args[]) 
    { 
        long x = 65; 
        long y = 41; 
  
        // Using mean(long x, long y) 
        // method of Guava's LongMath class 
        long ans = LongMath.mean(x, y); 
  
        // Displaying the result 
        System.out.println("Mean of " + x + " and "
                           + y + " is:" + ans); 
    } 
}

输出：

Mean of 65 and 41 is:53
