用Scanner类读取用户输入Java

Posted 2021-02-25

This snippet will allow you to read user's input when they write in the console. This method uses the Scanner class, which is my favorite way of doing instead of using the Buffered Reader, with the Scanner, you can also read from a file.

import java.util.Scanner;
public class ReadUserInput {
 
	public static void main(String[] args) {
 
		Scanner sc = new Scanner(System.in); //Creates the scanner and tells it
		//to read from the keyboard(System.in)
		String name; // The variable which is going to store the user's input 
		System.out.println("Enter your name.");
		name = sc.nextLine(); //Sets name equal to user's input
		//if you just call the "next" method, the Scanner will read up to the first space.
		System.out.println("Hello " + name);//Greets the user
 
	}
 
}
