Erro na Leitura do Double

Olá pessoal, ainda é sobre a entrada pelo teclado. O meu código sequencial ao inicial é dado por:

package General;

    import java.util.Scanner;
/**

Aonde eu peço para ele ler variáveis do tipo Double no objeto PhysicalProperties(). Ele está dando o seguinte erro quando ele lê a primeira variável: Leitura do Double

ou

2 How many steps in the Jacobi iteration? 2 How many iterations to save? 50 What is the flow attack angle (in degrees)? 0.0 Exception in thread "main" java.util.InputMismatchException at java.base/java.util.Scanner.throwFor(Scanner.java:939) at java.base/java.util.Scanner.next(Scanner.java:1594) at java.base/java.util.Scanner.nextDouble(Scanner.java:2564) at renecoreflows2d/General.ReadingData.ReadingTableProcedure(ReadingData.java:64) at renecoreflows2d/General.ReadingData.main(ReadingData.java:21)

Ou seja, ele acusa erro de formato do Double. Peço para que dêem uma olhada e me ajudem mais um pouco. Obrigado, Edisson Sávio.
