I migrated from C to Java and would like to know which command allows the user to enter external data and what would this command look like in code.

In language in C use the code below:

scanf(%tipo_da_variavel, &nome_da_variavel);
java c

    Which command you use in C?

  • In C it would be scanf(%type_da_variable, &variable_name);

  • In java is Scanner ler = new Scanner(System.in); int n = ler.nextInt();

The scanf() in C is equivalent to Scanner in Java. See below for an example:

Scanner scanner = new Scanner(System.in);

// valores do tipo inteiros
int n = scanner.nextInt();

// valores do tipo strings
String s = scanner.nextLine(); 

// valores do tipo double
double d = scanner.nextDouble();

See more details and examples in the documentation on the scanner class.
