System.out.printf
和 System.out.format
是否完全一样,或者它们在某种程度上有所不同?
Are System.out.printf
and System.out.format
totally the same or perhaps they differ in somehow?
System.out
是一个 PrintStream
,并引用 PrintStream.printf
System.out
is a PrintStream
, and quoting the javadoc for PrintStream.printf
这个方法的调用form out.printf(l, format, args)
行为方式与调用完全相同out.format(l, format, args)
An invocation of this method of the form
out.printf(l, format, args)
behaves in exactly the same way as the invocationout.format(l, format, args)
