Java String格式化具有不同变量类型的行

Question

I need to put for example 5 spaces after the first variable

2 spaces_go_here 300 batch ordered (due on day 7)

this is the format of the line and it consists of an Integer + Integer + String

I've tried the following but without success.

System.out.printf("%-5d%d%s",i + " " + testProduct.getQuantity() + " batch");

Although printf("%-5s%s",.. works if I'm trying to put spaces in between two Strings

Answer 1

The arguments to the Variadic function PrintStream.printf(String, Object...) are comma separated, this

System.out.printf("%-5d%d%s",i + " " + testProduct.getQuantity() + " batch");

should be something like

System.out.printf("%-5d%d%s",i, testProduct.getQuantity()," batch");

Or

System.out.printf("%-5d%d batch",i, testProduct.getQuantity());
