Программа не отображает вывод правильно

Question

Я пишу программу, которая должна отображать вывод, основанный на некоторых введенных числах. Я получаю вывод, и он полностью пуст, и ни один из расчеты выполняются

Вы не должны всегда пытаться format выход, если нет необходимости.

Вот ваша проблема:

 System.out.printf("%nAS OF "); 
     System.out.printf("%1$TB %1$Td, %1$TY%n", dateTime); 
     System.out.printf("%nTotal Stock Cost: $" + totalStockCost); 
     System.out.printf("%nTotal Online Fees: $", totalOnlineFees); 
     System.out.printf("%nTotal Commissions: $", totalCommissions); 
     System.out.printf("%n%nTOTAL COST: $", totalCost); 

Вы должны будете заменить большинство из них с последующим

 System.out.printf("%nAS OF "); 
     System.out.printf("%1$TB %1$Td, %1$TY%n", dateTime); 
     System.out.println("Total Stock Cost: $" + totalStockCost); 
     System.out.println("Total Online Fees: $" + totalOnlineFees); 
     System.out.println("Total Commissions: $" + totalCommissions); 
     System.out.println("TOTAL COST: $" + totalCost); 

Вот результат я получаю:
