Java receiving console data types-Input

Java beginners can easily understand the output class method system. Out. println ("Hello, Java! ");

However, it is not clear about the input, that is, receiving user input data in the console.

I have searched for a long time on the Internet on my own book, with a lot of information and disorder.

In a Java learning video, we can see the input class usage.

Public class inputfromconsole {public static void main (string [] ARGs) {S = new partition (system. in); string name = S. nextline (); int ival = S. nextint (); system. out. println (ival + "," + name );}}

 

First, create an object S. The initial value of the constructor is system. in, and then use S. nextint () is used to receive the ival value of an int type data. nextline () to receive string-type names and then output them separately.

An error is prompted during compilation because the handler class is in a package named util.

InProgramAdd import java. util. *; at the beginning to solve the problem.

 

Import Java. util. *; public class inputfromconsole {public static void main (string [] ARGs) {S = new feature (system. in); string name = S. nextline (); int ival = S. nextint (); system. out. println (ival + "," + name );}}
