[英]do while loop with multiple conditions in JAVA
The program keeps track of the product and quantity of the product in a do while loop and can only end if the user inputs the string "ZZZZ" and the integer 0. For example, inputting ZZZZ and 5 would not end the loop.程序在 do while 循环中跟踪产品和产品数量,只有在用户输入字符串“ZZZZ”和整数 0 时才能结束。例如,输入 ZZZZ 和 5 不会结束循环。 But somehow it's still ending.
但不知何故它仍然结束。
while (!itemcode.equals("ZZZZ") && (quantity != 0));
The output that I'm getting is我得到的输出是
Please enter the product code and quantity: ZZZZ 5
A105: 0 Price = 0.0
A207: 0 Price = 0.0
D671: 0 Price = 0.0
X111: 0 Price = 0.0
X902: 0 Price = 0.0
Total Price: $0.0
Which ends the loop but shouldn't.哪个结束循环但不应该。
我认为你真正想要的是:
while (!(itemcode.equals("ZZZZ") && quantity == 0));
