Java番石榴 |带示例的 LongMath 类的均值(long x,long y)

Guava 的 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,四舍五入到负无穷大。此方法具有溢出弹性。

句法:

public static long mean(long x, long y)

参数:此方法接受两个长类型参数 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(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

示例 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
