import java.lang.reflect.Modifier;
public class ReflectMethodtoStringExample1
 {
  public static void main(String... args) throws Exception {
    Class<?> cls = Class.forName("java.lang.String");
    Constructor[] allConstruc = cls.getDeclaredConstructors();
    for (Constructor constr : allConstruc) {
         System.out.println(" toString  : " + constr.toString());
      }
  }
}

Output:

toString  : public java.lang.String(java.lang.StringBuffer)
 toString  : public java.lang.String(byte[])
 toString  : public java.lang.String(int[],int,int)
 toString  : public java.lang.String()
 toString  : public java.lang.String(char[])
 toString  : public java.lang.String(java.lang.String)
 toString  : public java.lang.String(char[],int,int)
 toString  : public java.lang.String(byte[],int)
 toString  : public java.lang.String(byte[],int,int,int)

Example 2

//import statements

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;

public class ReflectMethodtoStringExample2  {

   public static void main(String[] args) {
 
     Method[] mthd = DemoJ1.class.getDeclaredMethods();
       for (Method constr : mthd) {
         System.out.println("toString  Of DemoJ1 : " + constr.toGenericString());
      }
      
      }
   }


class DemoJ1 {
   private String Field;

   public DemoJ1() throws ArrayIndexOutOfBoundsException {
   }

   private DemoJ1(String Field){
      this.Field = Field;
   }

   public String getField() {
      return Field;
   }

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