英文:
How would I print a statement with a number at the end, but set the number from right to left at a certain lenght?
问题
我对编程非常陌生，除了简单的格式设置和布尔语句外，我一无所知。我想要打印的内容是：
总工资： $ 0.00
我的代码是：
System.out.printf("总工资： " + "$" + "%.2f\n", grossPay);
输出结果是：
总工资： $0.00
我相信我应该从右到左打印，长度为7个空格。我应该如何做到这一点？
编辑：抱歉，我没有提供更多具体细节。我不是在询问代码是否有效，而是在问如何使输出完全符合 总工资： $ 0.00，保留所有的空格。我的实际问题是如何让 $ 0.00，在 $ 和 0.00 之间的 3 个空格是自动的，而不仅仅是用 + " " + 。
英文:
I'm very new to coding, and this I don't know anything beyond simple formatting and Boolean statement. What I'm trying to print is:
Gross Pay: $ 0.00
My code is:
System.out.printf("Gross Pay: " + "$" + "%.2f\n", grossPay);
and the output is
Gross Pay: $0.00
I believe I'm suppose to print from right to left with 7 space length. How would I do that?
EDIT: Sorry I wasn't more specific. I wasn't necessary asking for if it's valid or not, but I was asking how to get it to be exactly Gross Pay: $ 0.00 with the space and all. My actual question is how to get the $ 0.00, having the space 3 between $ and 0.00 being automatic as oppose to just doing + " " + .

以下是翻译好的内容：
类似这样的代码应该可以工作（已编辑）：
String.format("%7.2f", value)
示例：
System.out.println("Gross Pay: $" + String.format("%7.2f", 10.01));
System.out.println("Gross Pay: $" + String.format("%7.2f", 100.01));
System.out.println("Gross Pay: $" + String.format("%7.2f", 1000.01));
System.out.println("Gross Pay: $" + String.format("%7.2f", 10000.01));
示例输出：
Gross Pay: $ 10.01
Gross Pay: $ 100.01
Gross Pay: $1000.01
Gross Pay: $10000.01
作为使用数字填充的替代方法，以下是一个带有数字填充的示例：
DecimalFormat currency = new DecimalFormat();
currency.setGroupingUsed(false);
currency.setMinimumIntegerDigits(12);
currency.setMaximumIntegerDigits(12);
currency.setMinimumFractionDigits(2);
currency.setMaximumFractionDigits(2);
currency.setDecimalSeparatorAlwaysShown(true);
System.out.println("Gross Pay: $" + currency.format(939394.02480240));
英文:
Something like this should work (Edited):
String.format("%7.2f", value)
Sample:
System.out.println("Gross Pay: $" + String.format("%7.2f", 10.01));
System.out.println("Gross Pay: $" + String.format("%7.2f", 100.01));
System.out.println("Gross Pay: $" + String.format("%7.2f", 1000.01));
System.out.println("Gross Pay: $" + String.format("%7.2f", 10000.01));
Sample Output:
Gross Pay: $ 10.01
Gross Pay: $ 100.01
Gross Pay: $1000.01
Gross Pay: $10000.01
As an alternative to using spaces, this is a sample with number padding:
DecimalFormat currency = new DecimalFormat();
currency.setGroupingUsed(false);
currency.setMinimumIntegerDigits(12);
currency.setMaximumIntegerDigits(12);
currency.setMinimumFractionDigits(2);
currency.setMaximumFractionDigits(2);
currency.setDecimalSeparatorAlwaysShown(true);
System.out.println("Gross Pay: $" + currency.format(939394.02480240));

可以这样打印的话也是有效的：System.out.printf("Gross Pay: " + "$ " + "%.2f\n", grossPay);
英文:
It could be valid if you print it like this: System.out.printf("Gross Pay: " + "$ " + "%.2f\n", grossPay); ?
