Java Guava | binomial() method of IntMath Class Last Updated : 23 Jan, 2019 Comments Improve Suggest changes Like Article Like Report The binomial(int n, int k) method of Guava's IntMath class accepts two parameters n and k and calculate the value of the binomial coefficient {n}\choose{k}. If the calculated value overflows the maximum value of an integer than the method returns Integer.MAX_VALUE or in other words the maximum value of an integer. Syntax : public static int binomial(int n, int k) Parameter: This method accepts two parameters n and k and calculate the value of the binomial coefficient {n}\choose{k}. Return Value : The method returns the binomial coefficient of n and k. Exceptions : The method binomial(int n, int k) throws IllegalArgumentException if n < 0, k < 0 or k > n. Below examples illustrate the binomial() method of IntMath class: Example 1 : Java // Java code to show implementation of // binomial(int n, int k) method of Guava's // IntMath class import java.math.RoundingMode; import com.google.common.math.IntMath; class GFG { // Driver code public static void main(String args[]) { int n = 5; int k = 2; // Using binomial(int n, int k) method of // Guava's IntMath class int ans = IntMath.binomial(n, k); System.out.println("Binomial Coefficient of " + n + " and " + k + " is : " + ans); int n1 = 15; int k1 = 9; // Using binomial(int n, int k) method of // Guava's IntMath class int ans1 = IntMath.binomial(n1, k1); System.out.println("Binomial Coefficient of " + n1 + " and " + k1 + " is : " + ans1); } } Output: Binomial Coefficient of 5 and 2 is : 10 Binomial Coefficient of 15 and 9 is : 5005 Example 2 : Java // Java code to show implementation of // binomial(int n, int k) method of Guava's // IntMath class import java.math.RoundingMode; import com.google.common.math.IntMath; class GFG { static int findBinomial(int n, int k) { try { // Using binomial(int n, int k) // method of Guava's IntMath class // This should throw "IllegalArgumentException" // as k < 0 int ans = IntMath.binomial(n, k); // Return the answer return ans; } catch (Exception e) { System.out.println(e); return -1; } } // Driver code public static void main(String args[]) { int n = 5; int k = 7; try { // Function calling findBinomial(n, k); } catch (Exception e) { System.out.println(e); } } } Output: java.lang.IllegalArgumentException: k (7) > n (5) Reference : https://google.github.io/guava/releases/20.0/api/docs/com/google/common/math/IntMath.html#binomial-int-int- Comment More infoAdvertise with us Next Article Java Guava | binomial() method of IntMath Class bansal_rtk_ Follow Improve Article Tags : Misc Java Java-Functions java-guava Practice Tags : JavaMisc Similar Reads Java Guava | mod() method of IntMath Class The mod(int x, int m) method of Guava's IntMath class accepts two parameters x and m and used to calculate the value of x modulus under m.
