Hi

ANy one help me correcting the below method to get a solution for

School ID , must be 7 or 8 digits. If 8 digits , the last should be a character and you should truncate the number to 7 digits when passing it to the proc .

The code i wrote , is wrong , pls help me correct it to achieve the above request .

private static String f_facilityID(Scanner scan) {
		boolean loopUntilGoodNumber;
		System.out.println("Enter Facility ID:");
		String facilityID = scan.next();
		int count = facilityID.length();
		System.out.println("The count is :"+count);
		if(count == 8){
			loopUntilGoodNumber =isIntNumber(facilityID);
			if(loopUntilGoodNumber ==  false){
				facilityID = facilityID.substring(0,7);
			}
		}
		return facilityID;
	}
	public static boolean isIntNumber(String scn1){
		try{
			Long.parseLong(scn1);
		}catch(NumberFormatException nfe){
			return false;
		}
		return true;
}

Please help me in good coding .

public static boolean isValid ( String id)
{
   let valid:= false
   let len: = length of id
   
   if( len > 6 && len < 9 )
   {
      try
          convert substring( 0, 6 ) of id to integer
          valid:= true
      catch Exception
      
      if( valid && len == 8 )
      {
          check if the character at id position 7 is a letter
          and assign true or false to valid
      
      }
   }
   
   return valid;

}

Convert the above into proper java but UNDERSTAND it. Look up the Java documentation for the String class and the Character class.
