scanner class api code example

Example 1: java scanner

import java.util.Scanner;

// import scanner 

Scanner myScanner = new Scanner(System.in); // Make scanner obj

String inputString = myScanner.nextLine(); // Take whole line

boolean inputBoolean = myScanner.nextBoolean(); //Boolean input

long inputLong = myScanner.nextLong(); //Interger,long ... input

Example 2: how to provide a long string in Java Scanner class

If you use the nextLine() method immediately following the nextInt() method, 
nextInt() reads integer tokens; because of this, the last newline character for 
that line of integer input is still queued in the input buffer and the next 
nextLine() will be reading the remainder of the integer line (which is empty). 
So we read can read the empty space to another string might work. Check below 
code.
import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();

        // Write your code here.
        double d = scan.nextDouble();
        String f = scan.nextLine();
        String s = scan.nextLine();

        System.out.println("String: " + s);
        System.out.println("Double: " + d);
        System.out.println("Int: " + i);
    }
}
