# Can we execute a program without main() method?

Yes, one of the way is static block but in previous version of JDK not in JDK 1.7\

```
class A3{    static{    System.out.println("static block is invoked");    System.exit(0);    }  }  
```

\

```
Output:static block is invoked (if not JDK7)
```

\
In JDK7 and above, output will be:\

```
Output:Error: Main method not found in class A3, please define the main method as:public static void main(String[] args)
```
