将对象添加到数组时出现问题 [英] Problem adding a object to an array
问题描述
这里是我要使用的指示
要求用户输入商店中有效车辆的数量（这个数字应介于1和100之间，包括在内）。在由输入的有效车辆数量控制的循环中，要求用户输入每个车辆数据（即品牌，型号，年份和价格）。您可以假设所有输入数据都是正确的，无需进行数据验证。输入汽车的所有输入数据后，构造函数使用参数构建Car对象，然后将Car对象保存在数组中。
这是我到目前为止所拥有的：

int p = stdin.nextInt （）;
Car C =新车（m，d，y，p）;

有谁可以帮我这个？在此先感谢ALI：P
here is the instructiions I am to use
Ask the user to input the number of effective cars in the shop (this number should be between 1 and 100, inclusively). In a loop, controlled by the inputted number of effective cars, ask the user to input each car data (i.e. make, model, year and price). You can assume that all input data is correct and no data validation is necessary. As soon as all input data for a car is entered, build a Car object by the constructor with parameters and then save the Car object in the array.
Here is what i have so far:
