Q. Can we execute a java program without main() method ?

• It depends upon the java version we are using.If we are using java 6,then by using the static block,we can execute a program without a main().But in java 7,even if we use static block,there should me main() compulsorily or else JVM will throw an exception-"java.lang.NoSuchMethodError:main"

• yes,it is possible by usung a static initializer block.for eg.,
  public class Gkcem {
  static {
  System.out.println("Avijit Gkcem");
  }
  }
