El método getType() de java.lang.reflect.Field utilizado para obtener el tipo declarado del campo representado por este objeto Field. Este método devuelve un objeto Class que identifica el tipo declarado
Sintaxis:
public String getType()
Parámetros: Este método no acepta nada.
Valor de retorno: este método devuelve un objeto Class que identifica el tipo declarado.
Los siguientes programas ilustran el método getType():
Programa 1:
// Java program to demonstrate getType() method
import java.lang.reflect.Field;
public class GFG {
public static void main(String[] args)
throws Exception
{
// Get the marks field object
Field field = User.class.getField("Marks");
// Apply getType Method on User Object
// to get the Type of Marks field
Class value = field.getType();
// print result
System.out.println("Type"
+ " is " + value);
// Now Get the Fees field object
field = User.class.getField("Fees");
// Apply getType Method on User Object
// to get the Type of Fees field
value = field.getType();
// print result
System.out.println("Type"
+ " is " + value);
}
}
// sample User class
class User {
// static double values
public static double Marks = 34.13;
public static float Fees = 3413.99f;
public static double getMarks()
{
return Marks;
}
public static void setMarks(double marks)
{
Marks = marks;
}
public static float getFees()
{
return Fees;
}
public static void setFees(float fees)
{
Fees = fees;
}
}
Producción:
Type is double Type is float
Programa 2:
// Java program to demonstrate getType() method
import java.lang.reflect.Field;
import java.time.Month;
public class GFG {
public static void main(String[] args)
throws Exception
{
// Get all field objects of Month class
Field[] fields = Month.class.getFields();
for (int i = 0; i < fields.length; i++) {
// print name of Fields
System.out.println("Name of Field: "
+ fields[i].getType());
}
}
}
Producción:
Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month Name of Field: class java.time.Month
