why public static void main code example
Example 1: public static void main(string args)
Class main {
Public static void main(String[] args) {
}
}
Example 2: why main method is public static void in java
public : “public” is an access specifier which can be used outside the class.
When main method is declared
public it means it can be used outside class.
static : To call a method we require object. Sometimes it may be
required to call a method without the help of object. Then we declare that
method as static. JVM calls the main() method without creating
object by declaring keyword static.
If we make the main method non-static,
JVM will have to create its object first and then call main() method which
will lead to the extra memory allocation.
void : void return type is used when a method does’nt return any value.
main() method doesn’t return any value, so main() is declared as void.
Example 3: java public static void main
public static void main(String[] args){
}
Example 4: what is public static void
PUBLIC- is access modifier. visible to the world.
Public means that the method is visible and can
be called from other objects of other types.
STATIC- is specifier, any feature that has static
, belongs to the class.This means that you can
call a static method without creating an
object of the class.
VOID- is a return type, the method does not
return any value. void means that
the method has no return value.
