What's new for me ? Java

Types to read input from user:

• Input a string and a number using BufferedReader:

InputStream inputStream = System.in;
Reader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String name = bufferedReader.readLine(); //Read a string from the keyboard
String sAge = bufferedReader.readLine(); //Read a string from the keyboard
int nAge = Integer.parseInt(sAge); //Convert the string to a number.

• A more compact version of the previous example:

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String name = reader.readLine();
String sAge = reader.readLine();
int nAge = Integer.parseInt(sAge);

• Even more compact using Scanner :

Scanner scanner = new Scanner(System.in);
String name = scanner.nextLine();
int age = scanner.nextInt(); 

Shortcuts in IntelliJ Idea:

• psvm + Tab = public static void main(String[] args)

• sout + Tab = System.out.println();
