Scanner Class in Java
文章来源 https://www.geeksforgeeks.org/scanner-class-in-java/
In Java, Scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings.
Using the Scanner class in Java is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming.
