• A static method can be invoked anywhere within the same class.

P.S.V.M(String[] args){
	m1()
}
public static void m1(){
	s.o.p("Hello");
}
public void m2(){
	m1();
}

• We can invoke a static method from one class to another using class name as a reference.

class Demo{
	P.S.V.M(String[] args){
	m1();
	demo2.m2()
}
public static void m1(){
	s.o.p("Hello");
}
}
class demo2{
	public static void m2(){
		S.O.P("Code 2 in statc method");	
	}
}

Definition

A static method in Java is a method that belongs to the class itself rather than to any specific instance of the class. This means that static methods can be called without creating an instance of the class. The static keyword is used to declare a static method.

Characteristics of Static Methods

• Class-Level Association: Static methods are associated with the class, not with instances. They can be invoked using the class name.
• Access to Static Data: Static methods can access static variables and other static methods directly. However, they cannot access instance variables or instance methods directly because they do not belong to any specific object.
• No this or super Keyword: Within a static method, you cannot use the keywords this or super, as they refer to instance-specific data.
• Memory Allocation: Memory for static methods is allocated once when the class is loaded, making them memory efficient.
• Cannot be Overridden: Static methods cannot be overridden in subclasses because they are resolved at compile time based on the reference type.

Syntax

To declare a static method, use the following syntax:

<access_modifier> static <return_type> <method_name>(<parameter_list>) {
    *// method body*
}

To call a static method:

<ClassName>.<methodName>(<arguments>);
