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 class class 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
