According to basic geometry, hypotenuse is nothing but the longest side of a right-angled triangle. It is the side which is opposite to the right angle of the triangle. To find the length of the hypotenuse of a right-angled triangle, the Pythagorean theorem is applied. According to this theorem, given two perpendicular sides of a triangle of length p and b, the hypotenuse can be found by the formula 
.
The Java.lang.StrictMath.hypot() is an inbuilt method of StrictMath class which is used to get the hypotenuse or the square-root of summation of the square of given two sides or arguments i.e. 
. The method excludes all the intermediate overflow and underflow. It gives rise to few special results:
- The method returns positive infinity when either of num1 or num2 is infinite.
- It returns NAN when either any argument is NAN and neither argument is infinite.
Syntax:
public static double hypot(double num1, double num2)
Parameters: The method accepts two parameters of Double type:
- num1: This is the first value or any one side.
- num2: This is the second value or the other side.
Return Value: The method returns i.e. length of hypotenuse.
Examples :
Input: num1 = 3
num2 = 4
Output: 5.0
Below programs illustrate the Java.lang.StrictMath.hypot() Method:
Program 1:
java
// Java program to illustrate the// Java.lang.StrictMath.hypot() Methodimport java.lang.*;public class Geeks { public static void main(String[] args) { double num1 = 11, num2 = 13.8; // It returns the hypotenuse double hypotlen = StrictMath.hypot(num1, num2); System.out.println("Length of hypotenuse of side " + num1 + " & " + num2 + " = " + hypotlen); }} |
Length of hypotenuse of side 11.0 & 13.8 = 17.647662734764623
Program 2:
java
// Java program to illustrate the// Java.lang.StrictMath.hypot() Methodimport java.lang.*;public class Geeks { public static void main(String[] args) { double num1 = -54, num2 = -24.8; // It returns the hypotenuse double hypotlen = StrictMath.hypot(num1, num2); System.out.println("Length of hypotenuse of side " + num1 + " & " + num2 + " = " + hypotlen); }} |
Length of hypotenuse of side -54.0 & -24.8 = 59.422554640473
Program 3:
java
// Java program to illustrate the// Java.lang.StrictMath.hypot() Methodimport java.lang.*;public class Geeks { public static void main(String[] args) { double num1 = 4; double positive_Infinity = Double.POSITIVE_INFINITY; double negative_Infinity = Double.NEGATIVE_INFINITY; double nan = Double.NaN; // When 1 or more argument is NAN double hypotlen = StrictMath.hypot(nan, num1); System.out.println("Hypotenuse length = " + hypotlen); // When both arguments are infinity hypotlen = StrictMath.hypot(positive_Infinity, negative_Infinity); System.out.println("Hypotenuse length = " + hypotlen); }} |
Hypotenuse length = NaN Hypotenuse length = Infinity
