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

import java.util.*; class a { void main () { Scanner in = new Scanner(System.in); System.out.print("Please enter you age: "); int age = in.nextInt(); System.out.print("Please enter today's date: "); int date = in.nextInt(); System.out.print("Please enter current month: "); int month = in.nextInt(); System.out.print("Please enter current year: "); int year = in.nextInt(); } } // ENJOY!!!!!!!

Scanner sc = new Scanner(System.in); String s = sc.next(); int n = sc.nextInt(); double d = sc.nextDouble(); float f = sc.nextFloat(); // more fast way BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String s = br.readLine(); // read line int c = br.read(); // read single char

//For continues reading a line import java.util.Scanner; Scanner in = new Scanner(System.in); while(in.hasNextLine()) { String line = in.nextLine(); System.out.println("Next line is is: " + line); }
