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
