Scanner类位于java.util包中，用于接收用户输入，实现与用户的交互。创建Scanner对象：通常使用System.in作为输入源来创建Scanner对象，例如：Scanner scanner = new Scanner;。Scanner类还有其他构造方法，但最常用的创建方式就是上述方式。获取用户输入的方法：next：返回字符串类型，读取用户输入的内容，并去除...
In the example below, we use different methods to read data of various types: Example importjava.util.Scanner;classMain{publicstaticvoidmain(String[]args){ScannermyObj=newScanner(System.in);System.out.println("Enter name, age and salary:");// String inputStringname=myObj.nextLine();// Nume...

java import java.util.Scanner; 接下来,我们就可以创建Scanner对象了。通常情况下,我们将Scanner与System.in关联起来,以便从键盘读取用户输入的数据。具体做法如下: java Scanner scanner = new Scanner(System.in); 二、基本的读取方法 1. next()方法 next()方法用于读取用户输入的下一个完整单词,它会自动过滤掉...

An instance of this class is capable of scanning numbers in the standard formats as well as in the formats of the scanner's locale. A scanner's initial locale is the value returned by the Locale.getDefault(Locale.Category.FORMAT) method; it may be changed via the useLocale(java.util....
