Field toGenericString() method in Java with Examples
Last Updated :
30 May, 2022
The toGenericString() method of java.lang.reflect.Field is used to return a string which represents this Field, including its generic type. The format of the string is the access modifiers for the field, if any, followed by the generic field type, followed by a space, followed by the fully-qualified name of the class declaring the field, followed by a period, followed by the name of the field. The modifiers are placed in canonical order as specified by “The Java Language Specification”. This is public, protected or private first, and then other modifiers in the following order: static, final, transient, volatile.
Syntax:
public String toGenericString()
Parameters: This method accepts nothing. Return: This method returns a string describing this Field, including its generic type. Below programs illustrate toGenericString() method:
Program 1:
Java
import java.lang.reflect.Field;
import java.time.Month;
public class GFG {
public static void main(String[] args)
throws Exception
{
Field[] fields
= Month. class .getFields();
for ( int i = 0 ; i < fields.length; i++) {
System.out.println(
"toGenericString of Field:\n"
+ fields[i].toGenericString());
}
}
}
|
Output:toGenericString of Field: public static final java.time.Month java.time.Month.JANUARY toGenericString of Field: public static final java.time.Month java.time.Month.FEBRUARY toGenericString of Field: public static final java.time.Month java.time.Month.MARCH toGenericString of Field: public static final java.time.Month java.time.Month.APRIL toGenericString of Field: public static final java.time.Month java.time.Month.MAY toGenericString of Field: public static final java.time.Month java.time.Month.JUNE toGenericString of Field: public static final java.time.Month java.time.Month.JULY toGenericString of Field: public static final java.time.Month java.time.Month.AUGUST toGenericString of Field: public static final java.time.Month java.time.Month.SEPTEMBER toGenericString of Field: public static final java.time.Month java.time.Month.OCTOBER toGenericString of Field: public static final java.time.Month java.time.Month.NOVEMBER toGenericString of Field: public static final java.time.Month java.time.Month.DECEMBER
Program 2:
Java
import java.lang.reflect.Field;
public class GFG {
public static void main(String[] args)
throws Exception
{
Numbers no = new Numbers();
Field field
= Numbers. class .getField("value");
System.out.println(
"toGenericString is\n"
+ field.toGenericString());
}
}
class Numbers {
public static short value = 13685 ;
}
|
Output:
