For example, the pattern "\\s+" will return no empty tokens since it matches multiple instances of the delimiter. The delimiting pattern "\\s" could return empty tokens since it only passes one space at a time. A scanner can read text from any object which implements the Readable ...

Java Scanner的hasNext()方法 在编程笔试(或者某些场景)中,可能存在这样的需求:程序被要求接收不确定数量的一些字符串或者是数字,然后对接收的数据进行相关的处理。 假设这样一个场景,程序被要求接收不定数量的一些整数,然后计算这些数字的和。来看下面这个程序: im
// for each line of text, assume it's in a variable called line String[] dataArray = line.split("//s+"); String name = dataArray[0]; String frequency = dataArray[1]; String cumulativeFrequency = dataArray[2]; String rank = dataArray[3]; ...
