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
  }}

java scanner

import java.util.Scanner;//import Scanner

Scanner input=new Scanner(System.in);//Create the scanner Obj

float numF = input.nextFloat();//Returns float
int num1 = input.nextInt(); //Returns int
byte byte1 = input.nextByte();//Returns Byte
long lg1 = input.nextLong();//Returns long
boolean b1 = input.nextBoolean();//Returns bool
double num2 = input.nextDouble();//Returns Double
String nome = input.nextLine();//Returns String

//execution is pause until you give input

how to use scanners in java

      	Scanner scan = new Scanner(System.in);
      	System.out.println("Type anything and the scanner will take that input and print it");
      	String next = scan.next();
      	System.out.println(next);
    } 
}

public class FullNameLetters {
    public static void main(String[] args) {
        System.out.println ("Enter the name: ");
        Scanner S1 = new Scanner(System.in);
        String name = S1.nextLine();
        System.out.println("Enter the last name: ");
        Scanner S2 = new Scanner(System.in);
        String lastname = S2.nextLine();
        int fullln = name.length() + lastname.length();
        System.out.println(fullln);
    }
}
