java.io包包含一个“PrintStream”类,该类有两种格式方法,可以用来替换“print”和“println”。这些方法“format”和“printf”彼此等效。熟悉的“系统”。out”恰好是“PrintStream”对象,因此您可以在“System.out”上调用“PrintStream”方法。因此,您可以在代码中以前使用过“print”或“println”的任何地方使用“for...

Formatting Numeric Print OutputEarlier you saw the use of the print and println methods for printing strings to standard output (System.out). Since all numbers can be converted to strings (as you will see later in this lesson), you can use these methods to print out an arbitrary mixture ...
