I'm starting to program in Java, what's wrong with this program?

Question

Java

I started programming in Java, I solve problems in informatics and study there, but the program does not compile on ideone.com and on other compilers.
What's wrong?

package myprogram;
import java.io.PrintStream;
import java.util.Scanner;

public class myprogram; {

  public static Scanner in = new Scanner(System. in );
  public static PrintStream out = System.out;

  {
    int a;
    a = in .nextInt();
    out.print(a / 10);
  }
}

Answer 1

the program does not compile on ideone.com and on other compilers, what is wrong?

The compiler outputs an error message. It says "what's wrong"

Answer 2

Doesn't compile due to ; after the class name
public class myprogram ; {
After compilation will not work due to the absence of the main method

Answer 3

Remove line
package myprogram

Answer 4

and to public static void main(String[] args) , you need to add trhrow IOExceptions

Answer 5
