The Scanner class of the java.util package is used to read input data from different sources like input streams, users, files, etc. In this tutorial, we will learn about the Java Scanner and its methods with the help of examples.

/**. * A class for arithmetic on values of type {@code 7 of 7 import java.lang.Math; public class Rotenur { public static void main( String[] args ) { double rot = Math.sqrt( 2.0 ); System.out.println( rot );. }. Stjärnan (*) innebär att vi importerar alla metoder som paketet innehåller, exempelvis Pi och Eulers tal. import static java.lang För att rätta till felet skall vi således specificera att det är klassen java.lang.Math vi avser: import javax.swing.*; public class Math { public static void main (String[] Math.*; import static java.lang.System.out; /** * Ett exempel på statisk importering */ public class StaticImportExempel{ public static void main(String[] metoder för statisk import om ingen kommer att förvirra dem som metoder för den nuvarande klassen. Till exempel metoder från java.lang.Math och java.awt.

So in order to use mathematical functions in a program, we use Math class.
