java scan long string code example

Example 1: scanner in java

import java.util.Scanner;		//Import Scanner in java

class classname{
  public void methodname(){
    Scanner s_name = new Scanner(System.in);	//Scanner declaration
    //Use Scanner object to take input
    int val1    =  s_name.nextInt();			//int
    float val2  =  s_name.nextFloat();			//float
    double val3 =  s_name.nextDouble();			//double
    string name =  s_name.nextLine();			//string
    char ch     =  s_name.nextLine().charAt(0);	//character
  }}

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);
    }
}
