java.lang.Math.hypot(double x, double y)


On this document we will be showing a java example on how to use the hypot(double x, double y) method of Math Class. The hypot() method returns the sqrt(x2 + y2). I will save you on complicated explanation, it is simply a method to get the hypotenuse of a triangle. This is helpful in a scenario where we are dealing with right triangle and we only knew the base and height. The following special cases must be noted:

  • If either argument is infinite, then the result is positive infinity.
  • If either argument is NaN and neither argument is infinite, then the result is NaN.

Most of the methods of the Math class is static and the hypot() method is no exception. Thus don’t forget that in order to call this method, you don’t have to create a new object rather use the method in the format Math.copySign(magnitude, sign).

Method Syntax

public static double hypot(double x, double y)

Method Returns

The hypot() method returns sqrt(x2 + y2) without intermediate overflow or underflow


Requires Java 1.5 and up

Java Math hypot() Example

Below is a java code demonstrates the use of hypot() method of Math class. The example presented might be simple however it shows the behavior of the hypot() method.

The above java example source code demonstrates the use of hypot() method of Math class. We simply ask for two user input and we use the Scanner class to parse it. Since we have used the nextLine() method to get the console value which is having a return data type of String thus we have used the Double.parseDouble() to transform it into double. The two inputs corresponds to the base and height of a triangle. The result of the hypot() method returns the hypotenuse of a right triangle with the base and height given.

Sample Output

Below is the sample output when you run the above example.
