hasNextLine():Returns true if there is another line in the input of this scanner. This method may block while waiting for input. The scanner does not advance past any input.(当执行该方法时,会有堵塞现象,待用户输入时,遇到换行符则返回true) 4.实例 import java.util.Scanner; public class Test...

The Scanner class is used to get user input, and it is found in the java.util package.To use the Scanner class, create an object of the class and use any of the available methods found in the Scanner class documentation. In our example, we will use the nextLine() method, which is ...
Both hasNext and next methods may block waiting for further input. Whether a hasNext method blocks has no connection to whether or not its associated next method will block. The findInLine(java.lang.String), findWithinHorizon(java.lang.String, int), and skip(java.util.regex.Pattern) methods...
