NoSuchFieldException

Specifies that the class doesn't have a field of a specified name.

class Employee {
    String address;
    String firstName, lastName;
    int id, age;
    String phoneNum;
}

import java.lang.reflect.Field;

public class GetFields {
   public static void main(String args[]) throws Exception{
       Employee emp = new Employee();
       Class myClass = emp.getClass();
       
       Field myField = myClass.getDeclaredField("salary");
       myField.set(emp, "Krishna");
   } 
}

Above class tries to access a field 'salary' of Employee, which is not present, so NoSuchFieldException thrown.
