Printf is used instead of println.
使用了printf而非println。
Figure 4 shows the output from the println calls.
图4显示了println调用的输出。
System. out. println("Input the number of array elements! ");
请输入数组的下标，即数组的个数。
System. out. println " this line is also executed." thread does not stopped .
尽管线程被中断，但并没有结束运行。这行代码还是会被执行。
When you call println langs, it calls the Node.toString() method, returning debug output.
当您调用printlnlangs 时，它会调用 Node.toString()方法，以便返回调试输出。
You also emit the string to the console using the println function (see the bottom left of Figure 5).
也可以使用println函数将字符串发到控制台(参见图5左下角)。
Note that the println call needs to be moved into a method so that it can be invoked from the handler.
注意println调用需要转移到一个方法中，这样就可以从处理程序中调用它。
Thus, if you make several println calls in succession, each string in the output will appear on a separate line.
这就说明，如果你连续调用多个println，结果中的每个字符串会单独占用一行。
The effect of this last println statement is to display the value of total after adding on the surrounding text.
最后这句println语句的作用是在文本之后显示total的值。
The sayHello() function takes one parameter, which it outputs to the console in the following println() statement.
sayHello()函数只有一个参数，它会使用println()语句将这个参数输出到控制台。
This means that everything you pass to print or println in your script will be included in the servlet's response.
这意味着传递给脚本内的print或println的任何东西都将会包含在此servlet的响应内。
The effect of the println method is to display the entire argument string on the console and then to return to the beginning of the next line.
println方法的作用就是在控制台中显示整个参数字符串然后返回到下一行的开头。
For now all we're interested in is println( ), which in effect means "print what I'm giving you out to the console and end with a new line."
它的意思是“把我给你的东西打印到控制台，并用一个新行结束”。
Println statements are quick and convenient but they do not offer the power of a full-featured logging system. Table 2 lists logging libraries for the Java platform
Println语句速度快且使用方便，但是它们没有提供全功能的日志记录系统所具有的功能。
"However, you could easily replace the println statement with functionality that interacts with a real coffee machine (I am looking forward to hearing from anyone who'd like to try this!")
但是您可以很容易地使用与真实咖啡机交互的功能替代println语句(我很希望有人能够如此尝试！)
To illustrate this point, one of his code snippets consistently runs in 4.9 seconds on his computer, but if he omits a println that displays the result, it consistently runs in 0.08 seconds.
为了说明这一点，他在他哦个一台计算机上连续运行了很多次相同的代码段，结果运行时都是4.9秒，但当他删除了打印结果的println语句之后，运行时间则缩短到0.08秒。
