Example 1

  //import statement
import java.lang.reflect.Constructor;
import java.lang.reflect.Method;
import java.lang.reflect.Modifier;
public class ReflectMethodtoGenericStringExample1
 {
  public static void main(String... args) throws Exception {
    Class<?> cls = Class.forName("java.lang.String");
    Method[] mthd = cls.getDeclaredMethods();
            for (Method constr : mthd) {
         System.out.println(" toGenericString  : " + constr.toGenericString());
      }
  }
}

 toGenericString  : public int java.lang.String.indexOf(int,int)
 toGenericString  : public int java.lang.String.indexOf(int)
 toGenericString  : static int java.lang.String.indexOf(char[],int,int,char[],int,int,int)
 toGenericString  : static int java.lang.String.indexOf(char[],int,int,java.lang.String,int)
 toGenericString  : public static java.lang.String java.lang.String.valueOf(int)
 toGenericString  : public static java.lang.String java.lang.String.valueOf(long)

Example 2

import java.lang.reflect.Constructor;

public class ReflectMethodtoGenericStringExample2 {

   public static void main(String[] args) {
 
      Constructor[] construct = DemoJ.class.getDeclaredConstructors();
      for (Constructor constr : construct) {
         System.out.println("toGenericString  Of DemoJ : " + constr.toGenericString());
      }    
      }
   }


class DemoJ {
   private String Field;

   public DemoJ() throws ArrayIndexOutOfBoundsException {
   }

   private DemoJ(String Field){
      this.Field = Field;
   }

   public String getField() {
      return Field;
   }

   public void setField(String Field) {
      this.Field = Field; 
   } 
}

Output:

toGenericString  Of DemoJ : public DemoJ() throws java.lang.ArrayIndexOutOfBoundsException
toGenericString  Of DemoJ : private DemoJ(java.lang.String)
