我无法在 BlueJ 中弄清楚的编译错误

Question

当我尝试对我的 print f 语句之一进行编译时，出现了“)”预期错误。该项目是编写一个应用程序，该应用程序将运行在比萨饼餐厅的收银机上显示。这是代码部分。问题行是双星号内的行。有什么想法吗？

System.out.println();
System.out.println ("       Order Summary ");
System.out.println (" *************************");
System.out.println ();

if(NofTopp = 0){
    System.out.printf( Size + ", " + crust + " Cheese Pizza : $%.2f", cost);
    System.out.println();
}else if(NofTopp = 1){
    System.out.printf( Size + ", " + crust + " Pizza with " + Top1 + ": $%.2f", cost);
    System.out.println();
}else if(NofTopp = 2){
    **System.out.printf (Size + ", " + crust + " Pizza with " + Top1 + " and " + Top2 ": $%.2f", 
 cost);**
    System.out.println();
}else if(NofTopp = 3){
    System.out.printf( Size + ", " + crust + " Pizza with " + Top1 + ", " + Top2 + " and " + Top3 + 
": $%.2f", cost);
    System.out.println();
}

System.out.printf ("Tax: $%.2f",SalesTax );
System.out.println();

System.out.printf ("Total: $%.2f",totalCost );
System.out.println();

Answer 1

我想你忘记了 ": $%.2f" 之前的 +。尝试：

System.out.printf (Size + ", " + crust + " Pizza with " + Top1 + " and " + Top2 + ": $%.2f", cost);
