Master the Technique of Calling Private Methods in Java: An Easy Guide

In Java, a private method can be called from within the class that it is declared, as they are not accessible from any other class directly.

*Understanding the concept of private methods*

Mastering Java: Calling Private Methods Java, a popular programming language, offers a unique feature – private methods. A private method is a member of a class that is not accessible directly from the outside world. So, how do you call a private method in Java? Let’s delve into that.

Understanding Private Methods Every Java class has methods that perform specific tasks. Some methods are public, meaning they can be accessed from anywhere. Others are private, hidden from external classes.

Private methods are typically used to perform internal operations that should not be exposed to the outside world. Calling Private Methods Normally, you can’t call a private method from outside its class. However, Java’s Reflection API provides a backdoor.

With it, you can access and invoke private methods from outside the class. Using Reflection API Java’s Reflection API allows inspection and manipulation of the inner workings of a class at runtime. To call a private method, use the Class.

getDeclaredMethod() method, followed by Method.setAccessible(true) to bypass Java’s access control checks. Next, use Method.

invoke() to call the private method. Caution Ahead While powerful, the Reflection API should be used sparingly. It can lead to code that is difficult to understand and maintain.

how to call a private method in java

Creating a private method in Java and calling it within the same class is straightforward. However, calling it from another class isn’t directly possible due to the access level restrictions in Java. But, you can use reflection to call a private method from another class. Here is an example: “`java import java.lang.reflect.Method; public class MyClass { private void myPrivateMethod() { System.out.println(“Private Method Called”); } public static void main(String[] args) { MyClass myClass = new MyClass(); try { Method method = MyClass.class.getDeclaredMethod(“myPrivateMethod”); method.setAccessible(true); method.invoke(myClass); } catch (Exception e) { e.printStackTrace(); } } } “` This code creates a new instance of MyClass, gets the Method object for myPrivateMethod, makes it accessible, and then invokes it. For creating a data driven HTML table with 3 columns, 6 rows and specific color formatting, you can use the following code: “`html
