Following is my code, which is a success on ideone.com, the onl9 compiler:
public class Main
{
public static void main (java.lang.String[] args) throws java.io.IOException
{
if(args.length != 2)
{
java.lang.System.exit(0);
}
java.io.BufferedReader br=new java.io.BufferedReader(new
java.io.InputStreamReader(java.lang.System.in));
java.lang.String str=br.readLine();
if(str.length() > 19 || str.length() < 1)
{
java.lang.System.exit(0);
}
java.lang.String num="";
java.io.FileOutputStream foutinp=new java.io.FileOutputStream(args[0]);
byte b[]=str.getBytes();
foutinp.write(b);
foutinp.close();
java.io.File f=new java.io.File(args[0]);
if(f.exists())
{
java.io.FileInputStream fininp=new java.io.FileInputStream(args[0]);
int ch;
while((ch=fininp.read()) != -1)
{
num+=(char)ch;
}
int len=num.length();
for(int i=0;i<len;i++)
{
if(!(num.charAt(i) >= '0' && num.charAt(i) <= '9'))
{
java.lang.System.exit(0);
}
}
if(len!=1)
{
num=num.charAt(len-2)+""+num.charAt(len-1);
}
else
{
num=""+num.charAt(len-1);
}
int no=java.lang.Integer.parseInt(num);
java.lang.String msg;
if(no==0)
{
msg="yes";
}
else
{
no=no%6;
if(no==0)
{
msg="yes";
}
else
{
no=no-1;
if(no==0)
{
msg="yes";
}
else
{
no=no-2;
if(no==0)
{
msg="yes";
}
else
{
msg="no";
}
}
}
}
java.io.FileOutputStream foutop=new java.io.FileOutputStream(args[1]);
byte bt[]=msg.getBytes();
foutop.write(bt);
foutop.close();
java.io.File f2=new java.io.File(args[1]);
if(f2.exists())
{
java.io.FileInputStream fin=new java.io.FileInputStream(f2);
msg="";

{
msg+=(char)ch;
}
java.lang.System.out.println(msg);
}
else

java.lang.System.exit(0);
}
}
else
{
java.lang.System.exit(0);
}
}
