The toGenericString() method of java.lang.reflect.Constructor class is used to return get the generic form of this constructor, i.e. a string representing the details about this constructor including the type parameters.
Syntax:
public String toGenericString()
Parameters: This method accepts nothing.
Return: This method returns a generic form of this constructor as a string that describes this Constructor along with the type parameters.
Below programs illustrate toGenericString() method:
Program 1:
// Java program to illustrate// toGenericString() method  import java.lang.annotation.Annotation;import java.lang.reflect.Constructor;  public class GFG {      public static void main(String[] args)    {        // create a class object        Class classObj = shape.class;          // get Constructor object        // array from class object        Constructor[] cons = classObj.getConstructors();          // check get string representation        String str = cons[0].toGenericString();          // print result        System.out.println("Constructor : " + str);    }      public class shape {          public shape(Object... objects)        {        }    }} |
Constructor : public GFG$shape(GFG, java.lang.Object...)
Program 2:
// Java program to illustrate// toGenericString() method  import java.lang.annotation.Annotation;import java.lang.reflect.Constructor;  public class GFG {      public static void main(String[] args)    {        // create a class object        Class classObj = String.class;          // get Constructor object        // array from class object        Constructor[] cons            = classObj.getConstructors();          for (int i = 0; i < cons.length; i++) {              String str = cons[i].toGenericString();              // print result            System.out.println(str);        }    }} |
