Taking user input in Java

user_input.java

//You can use any of the following options based on the requirements.

//Scanner class

Scanner scan = new Scanner(System.in);
String s = scan.next();
int i = scan.nextInt();

//BufferedReader and InputStreamReader classes

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s = br.readLine();
int i = Integer.parseInt(br.readLine());


//DataInputStream class
DataInputStream dis = new DataInputStream(System.in);
int i = dis.readInt();
The readLine method from the DataInputStream class has been deprecated. To get String value, you should use the previous solution with BufferedReader

//Console class

Console console = System.console();
String s = console.readLine();
int i = Integer.parseInt(console.readLine());

//Apparently, this method does not work well in some IDEs.
