static methods in java code example
Example 1: static in java
using static before a method or variable we can access it by not creating a
instance of it.in the program we directly used student.cube(5)
class Calculate{
static int cube(int x){
return x*x*x;
}
public static void main(String args[]){
int result=Calculate.cube(5);
System.out.println(result);
}
}
Example 2: why we use static in java
In Java, static keyword is mainly used for memory management.
It can be used with variables, methods, blocks and nested classes.
It is a keyword which is used to share the same variable or method of a given
class. Basically, static is used for a constant variable or a method
that is same for every instance of a class
Example 3: what is static method
A static method belongs to the class rather than the object.
There is no need to create the object to call the static methods.
A static method can access and change the value of the static variable
Example 4: static in java
static keyword is a non-access modifier. static keyword can be used with
class level variable, block, method and inner class or nested class.
Example 5: do i have to use static methods in java main
Use a static method
when you want to be able to access the method
without an instance of the class
Example 6: static in java

variables, methods, blocks and nested classes. The static keyword belongs to the class
than an instance of the class.
The static can be:
Variable (also known as a class variable)
