Thread: How to repeat a while loop?

I need my program to repeat the while loop if the student number = 0. How would you do this?

class Main
{
  public static void main( String args[] )
  {
    System.out.print("#Student Number:" );
    int student = BIO.getInt();
 
    System.out.print("#Coursework Mark:" );
    int coursework = BIO.getInt();
 
    System.out.print("#Exam Mark:" );
    int exam = BIO.getInt();
 
    while ( student > 0 )
    {
      double result = (double) (exam + coursework) / 2;
        System.out.print( "SN=");
        System.out.print( student );
        System.out.print( " EX=  ");
        System.out.print( exam );
        System.out.print( " CW=  ");
        System.out.print( coursework );
        System.out.print( " Mark =  ");
        System.out.println( result );
 
        System.out.print("#Student Number:" );
        student = BIO.getInt();
        System.out.print("#Coursework Mark:" );
        coursework = BIO.getInt();
        System.out.print("#Exam Mark:" );
        exam = BIO.getInt();
    }
if ( student == 0)
{
 
}
  }
 
}

My university want me to have the data be terminated when a 0 is entered.
