static block:
It is the class level one time execution block.After the compilation of the program when we go for running by using the command java <class name> then only the corresponding class will loaded in to RAM and 1st of all the static block of that class will execute even it run before the main method run.
->We place the class level initialization logic here like initialization of static variable.
Ex:
class Alpha
{
static
{
System.out.println("Alpha:static");
}
public void show()
{
System.out.println("Alpha:Show()");
}
}
public class Bita
{
static
{
System.out.println("Bita:static");
}
public static void main(String args[])
{
Alpha a=new Alpha();
a.show();
}
}
OUTPUT:
Bita:static
Alpha:static
Alpha:Show()
.......................
STATIC METHOD:
static method is a method which can loaded into the RAM without any object only class name is enough.
->Actually what happen fnds??A function will execute whn ever it only loaded into the RAm through a object.But some times our requirement is like this ,we have to execute a function but at that time no object cant be created for that
class.at that moment static method is very necessary
(consider about main method of java).
->static method and static variable does not allocated memory in object.but it allocate memory in CONTEXT area of that class.
EX:
class Gamma
{
int count1;
static int count2;
static void show()
{
System.out.println("Gamma:show()");
count1++;//error bcz non static variable.
count2++;//ok
}
public static void main(String args[])
{
Gamma.show();
}
}
