If the argument passed is positive zero or negative zero then the result will be same as that of the argument.

Import java lang math sqrt.

In java we use the math class to compute square roots. Static import means that the fields and methods in a class can be used in the code without specifying their class if they are defined as public static. In java static import concept is introduced in 1 5 version. The math class method sqrt in the package java lang is static imported.

A program that demonstrates this is given as follows. Sqrt can be called as java lang math sqrt. If the argument is nan or negative then the result is nan. Instead we directly access math sqrt using its composite name.

With the help of static import we can access the static members of a class directly without class name or any object. It shows the output of sqrt. Static import is a feature that expands the capabilities of import keyword. If the argument.

Using static import it is possible to refer to the static member directly without its class name. If the argument is nan or less than zero the result is nan. It is used to import static member of a class. This method returns.

If the argument is positive infinity then the result is positive infinity. Special cases this method returns the positive square root of a. We all know that static member are referred in association with its class name outside the class. The java lang math sqrt returns the square root of a value of type double passed to it as argument.

The syntax is as follows. We always use sqrt method of math class by using math class i e. This java tutorial shows how to use the sqrt double a method of math class under java lang package. In mathematics a square root maps the area of a square to the length of its side.

The java lang math sqrt double a returns the correctly rounded positive square root of a double value. Math sqrt but by using static import we can access sqrt method directly. If the argument is nan or less than zero this method will return nan. It does not import java lang math at its top.

Static import in java. If the argument is positive double value this method will return the square root of a given value.
