Console input Statements

To use the Scanner class, the import Java.util.Scanner should be imported first;

The object is then established Scanner sc = new Scanner (system.in);

You can then receive a variety of data types from the console input.

Like what:

String s = sc.next ();//Receive console input for various data types

String s = sc.nextline ();//Receive console input for various data types

The difference between next and Nextline is that the former receives a string up to the first space, and the latter receives a string that can contain a space, until the carriage return.

Double d = sc.nextdouble ();

If you want to enter a character, you can take advantage of the Charat (index) method of the string.

For example, char ch = sc.next (). charAt (0);

You can also write directly: char ch = new Scanner (system.in). Next (). charAt (0);

Integral type: int a=new Scanner (system.in). Nextint ();

Floating point: Float b=new Scanner (system.in). Nextfloat ();

Floating point: Double b=new Scanner (system.in). nextdouble ();

String: String S=new Scanner (system.in). Next ();

String s=new Scanner (system.in). nextline ();

Ways to get characters:

char ch = new Scanner (system.in). Next (). charAt (0);
