Field getName() method in Java with Examples

The getName() method of java.lang.reflect.Field used to get the name of the field represented by this Field object. When a class contains a field and we want to get the name of that field then we can use this method to return the name of Field.
Syntax:
public String getName()
Parameters: This method accepts nothing.
Return value: This method returns a String which is the simple name of the underlying member.
Below programs illustrate getName() method:
Program 1:
// Java program to demonstrate getName() 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 getName Method on User Object // to get the name of Marks field String value = field.getName(); // print result System.out.println("Name" + " is " + value); // Now Get the Fees field object field = User.class.getField("Fees"); // Apply getName Method on User Object // to get the name of Fees field value = field.getName(); // print result System.out.println("Name" + " is " + value); // Now Get the name field object field = User.class.getField("name"); // Apply getName Method on User Object // to get the name of name field value = field.getName(); // print result System.out.println("Name" + " is " + value); }} // sample User classclass User { // static double values public static double Marks = 34.13; public static float Fees = 3413.99f; public static String name = "Aman"; 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; } public static String getName() { return name; } public static void setName(String name) { User.name = name; }} |
Output:
Name is Marks Name is Fees Name is name
Program 2:
// Java program to demonstrate getName() 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].getName()); } }} |
Output:
Name of Field:JANUARY Name of Field:FEBRUARY Name of Field:MARCH Name of Field:APRIL Name of Field:MAY Name of Field:JUNE Name of Field:JULY Name of Field:AUGUST Name of Field:SEPTEMBER Name of Field:OCTOBER Name of Field:NOVEMBER Name of Field:DECEMBER
