Java ArrayList使用array.add（）同时添加行和列，如何仅添加行或列？

我有以下代码：

playerInventory.add(temp);
System.out.println("You've purchased " + temp.getName());
balance -= temp.getPrice();
runningWeight -= temp.getWeight();
System.out.println("Your new balance " + balance + ", and your wagon can carry " + runningWeight + " more pounds of products.\nPress enter to continue shopping.");
Scanner cont = new Scanner(System.in);
String enterToContinue = scan.nextLine();

for(int i = 0; i < playerInventory.size(); i++)
    System.out.println(playerInventory);

如何使其只显示一行中的项目？

您的打印有问题：

for(int i = 0; i < playerInventory.size(); i++)
    System.out.println(playerInventory);

使用

System.out.println（playerInventory.get（i））@baraky解决了，非常感谢！快速提问，数组列表以这种方式存储东西是正常的，还是只是我打印它的方式让它看起来很奇怪？只是打印而已。数组只有3个元素长[Item1，Item2，Item3]
for(int i = 0; i < playerInventory.size(); i++)
    System.out.println(playerInventory);

for(int i = 0; i < playerInventory.size(); i++)
    System.out.println(playerInventory.get(0));
