Runtime Error running in UVA

Hi all ,im new with java, i write a code which working fine in my machine but when i submit to UVA web it produce runtime error,could anyone help me identify what is the cause of that problem
.It does not show any specific error for me to look into, it just say that my program didnt finish properly.
here is my code
Code :
