Java格式字符串间距

[英]Java Format String Spacing

I've been looking through the forum to find an exact answer to this, but have been unable to do so. 我一直在论坛中寻找有关此问题的确切答案,但一直未能做到。 Here is my code: 这是我的代码:

String item = String.format("%-6s $%-6.2f Number in Inventory: %-3d", this.getBarcode(), this.getPrice(), this.getInventory());

The output looks like this for two items put in: 输入的两个项目的输出看起来像这样:

DR4423 $700.04 Number in Inventory: 24 
LD342  $1234.24 Number in Inventory: 425

The output should look like this, with an extra character space in the price for Number in Inventory to line up: 输出应如下所示,在价格中要有一个额外的字符空间,以使“库存中的数字”排队:

DR4423 $ 700.04 Number in Inventory: 24 
LD342  $1234.24 Number in Inventory: 425

How do I make the "Number in Inventory" line up? 如何使“库存编号”排队? It looks like the first item in the example lost an empty character space as it only has 5 digits instead of 6 for the price. 看起来示例中的第一项丢失了一个空字符空间,因为它只有5位数字而不是价格的6位数字。 Thanks in advance for the help. 先谢谢您的帮助。

I think you need to use: 我认为您需要使用:

String.format("%-6s $%-7.2f Number in Inventory: %-3d", this.getBarcode(), this.getPrice(), this.getInventory());

Or, if you want the space added to the front: 或者,如果您想在前面添加空间:

String.format("%-6s $%#7.2f Number in Inventory: %-3d", this.getBarcode(), this.getPrice(), this.getInventory());

Notice the %-7 instead of %-6 . 注意%-7而不是%-6 The period is counted as a character. 句点被视为字符。

在价格和“数字”之间插入\\t应该可以正常工作。

- in %-6.2f means you want passed number to be aligned to left, like: -%-6.2f表示您希望传递的数字向左对齐,例如:

|123,45|
|123,40|
|123,00|
|12,00 |
|1,00  |

If you want to align your number to right like: 如果您想将数字右对齐,例如:

|123,45|
|123,40|
|123,00|
| 12,00|
|  1,00|

then simply remove this - . 然后只需删除此-

You should should also probably set minimal used length to 7 since . 从开始,您还应该将最小已用长度设置为7 . also takes some space which means that to produce 也需要一些空间

| 700.04|
 1234567

you need 7 characters. 您需要7个字符。

So try with %-6s $%7.2f Number in Inventory: %-3d 因此,请尝试使用%-6s $%7.2f Number in Inventory: %-3d
