Just came to know that javadoes has a method named printf, then what is the difference between printf& println?
才知道java确实有个方法叫printf，那么printf& 有println什么区别呢？
回答by Ryan Shukis
System.out.println();is efficient for simply printing a line of text. If the line of text needs to be formatted (ex: alignment (left-justified, etc.), etc.), then System.out.printf();would be used.
System.out.println();对于简单地打印一行文本是有效的。如果需要格式化文本行（例如：对齐（左对齐等）等），则将System.out.printf();使用。
