Field getType() method in Java with Examples

Last Updated : 26 Aug, 2019

The getType() method of java.lang.reflect.Field used to get the declared type of the field represented by this Field object.This method returns a Class object that identifies the declared type Syntax:

public String getType()

Parameters: This method accepts nothing. Return value: This method returns a Class object that identifies the declared type. Below programs illustrate getType() method: Program 1:

Java

// 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;
    }
}

Output:

Type is double
Type is float

Program 2:

Java

// 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());
        }
    }
}

Output:

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
