Java Guava | mean(long x, long y) of LongMath Class with Examples

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

My Personal Notes arrow_drop_up In love with a semicolon because sometimes i miss it so badly)
