Java Guava | mean(long x, long y) of LongMath Class with Examples
  • Last Updated : 28 Jan, 2019

The mean(long x, long y) method of Guava’s LongMath Class accepts two parameters x and y and calculates arithmetic mean of them rounded towards negative infinity. This method is overflow resilient.

Syntax:

public static long mean(long x, long y)

Parameters: This method accepts two parameters x and y which are of long type.

Return Value: The method returns arithmetic mean of x and y, rounded towards negative infinity.

Exceptions: The method doesn’t have any exception.



Example 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);
    }
}
Output:
Mean of 1542 and 421 is : 981

Example 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);
    }
}
Output:
Mean of 65 and 41 is : 53
