Answer / amit singh

yes you can run java peogram without main
we do it through the static block ,because its execute
before the main method,
so when the class is loaded it will execute before main
but whrn the static block excute and after exiting it jvm
search for main when it will not fou8nd it then it throw
some exception so for this we use the
System.exit();
class Moon
{
static
{
System.out.println("hello i am visible without main");
}
System.exit();
}
Thanks amit singh

Answer / a.d. vijaykumaran

Yes. static is powerful word in java because of within
static block inside we can define statement and then
System.exit(0); use this to avoid runtime error main thread
exception error.
class Beatme //we can use any abstract class or interface
{
static // we can't do throws Exception
{
System.out.println("A.D.Vijaykumaran");
System.exit(0);
}
}

and one disadvantage above the program as doesn't
define "System defined Exception r throws Exception" .

Answer / shaik baji

Yes, we can execute the java program with out the main
method by using the the static block. After executing the
static block the JVM will search for the main method so to
skip this we should call System.exit(int) method.

NOTE: System.exit method contains integer parameter so we
shoud pass the integer value.
class MainDemo
{
static
{
System.out.println("hello i am visible without
main");
System.exit(0);
}

}

Answer / naga

yes,we can write and run a java program without using the
main method.
i.e By using static

example program...!

public void static( )
public class
{
public void static( )
{
System.out.println( "Without main method" );
System.exit(0);
}
}

Answer / rammohan

with out main() and static block also run java program
through static obj creation
class nomainnostatic
{
nomainnostatic()
{
System.out.println("vaaniMohan");
System.out.println("hai");
System.exit(1);
}
static nomainnostatic n=new nomainnostatic();
};
support some jdk versions only
exp:when ever static obj is created the default constructor
will be called,so the constructor block will be executed.
