static use 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: 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 3: java what is static
In the Java programming language, the keyword static indicates that the particular member belongs to a type itself,
rather than to an instance of that type.
This means that only one instance of that static member is created which is shared across all instances of the class.
Example 4: static in java
The static keyword in Java is used for memory management mainly. We can apply static keyword with
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)
Method (also known as a class method)
Block
Nested class
Example 5: Static method in java
We can declare a method as static by adding keyword “static” before method name.
Let’s see example on static method in java.
public class StaticMethodExample
{
static void print()
{
System.out.println("in static method.");
}
public static void main(String[] args)
{
StaticMethodExample.print();
}
}
Example 6: what is static keyword in java
Static keyword is used a lot in java.
Static means, you
can access those static variables
without creating an object,
just by using a class name.
This means that only one instance of
that static member is created which
is shared across all instances of the class.
Basically we use static keyword when
all members share same instance.
