Overloading
static method In Java
Yes, we can overload the static method in Java. In terms of method
overloading, the static method is just like normal methods. To overload the static method, you need to provide another static method with the same name but a different method signature. The static overloaded method is resolved using Static
Binding during compile time. The overloading method in Java is completely
different than the overriding method. As discussed in the last article, we can
not override the static method in Java, but we can certainly overload a static
method in Java. Here is an example that confirms that we can overload static method in Java:
Overloading Static method in Java - example
In this example, we have a static method called greet(String
name) which takes a string argument as a name and print a default greeting message as "Hello
John".
Now to show that we can overload the static method in Java, I have provided
another static method with the same name but a different method signature takes the name of a person to greet and greeting a message like Good Morning, Good Evening, etc.
Here is our complete Java program to demonstrate that static method can be overloaded in Java:
/**
* Java program to show that we can overload static method in Java.
*/
public class StaticOverloadingTest {
public static void main(String args[]) {
greet("John"); //will call a static method with one String argument
greet("John," "Good Morning"); //overloaded static method will be call
}
/*
* static method which will be overloaded
*/
public static void greet(String name){
System.out.println("Hello " + name);
}
/*
* Another static method that overloads above Hello method
* This shows that we can overload static method in Java
*/
public static void greet(String name, String greeting){
System.out.println(greeting + " " + name);
}
}
Output
Hello John
Good Morning John
* Java program to show that we can overload static method in Java.
*/
public class StaticOverloadingTest {
public static void main(String args[]) {
greet("John"); //will call a static method with one String argument
greet("John," "Good Morning"); //overloaded static method will be call
}
/*
* static method which will be overloaded
*/
public static void greet(String name){
System.out.println("Hello " + name);
}
/*
* Another static method that overloads above Hello method
* This shows that we can overload static method in Java
*/
public static void greet(String name, String greeting){
System.out.println(greeting + " " + name);
}
}
Output
Hello John
Good Morning John
That's all on How can we overload static methods in Java. In summary,
Don't confuse between method
overloading and method overriding. In short, you can overload the static method
in Java, but you can not override the static method in Java.

ofcourse you can not overload static method, but you can hide them in Java.
ReplyDeleteyou can overload but not override static methods
DeleteI am new to java. Your blog is really good. It helps me in learning java. Keep writing more articles.
ReplyDeleteIs it method hiding
