how to read input in java

1import java.util.Scanner; /* Required Import*/
2public class reading{
3  public static void main(String[] args){
4    Scanner scan = new Scanner(System.in); // Create Reader 
5    System.out.print("Enter Your Age"); // Ask the user for something
6    int age = scan.nextInt(); // Read value from user
7    System.out.print(age); // Output the value
8  }
9}
10/*
11  Java Reading Options:
12  1_ reading int => nextInt();
13  2_ reading char => next().charAt(0); Single Character
14  3_ reading string => next();
15  4_ reading double => nextDouble();
16*/

1String str = System.console().readLine();

1Scanner sc = new Scanner(System.in);  // Create a Scanner object
2String userName = sc.nextLine();//read input string
3int age = sc.nextInt(); //read input integer
4long mobileNo = sc.nextLong(); //read input long
5double cgpa = sc.nextDouble(); //read input double
6System.out.println(userName);//output

7// more fast way
8BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
9String s = br.readLine(); // read line
10int c = br.read();        // read single char

1//For continues reading a line
