how to use scanners in java

import java.util.Scanner;

Public class Scanner {
	Public static void main(String[] args) {
    	// Scanner *scanner name here* = new Scanner(System.in);
      	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);
    } 
}

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

Java scanner example

import java.util.Scanner;
public class AddTwoNumbers2 {

    public static void main(String[] args) {
        
        int num1, num2, sum;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter First Number: ");
        num1 = sc.nextInt();
        
        System.out.println("Enter Second Number: ");
        num2 = sc.nextInt();
        
        sc.close();
        sum = num1 + num2;
        System.out.println("Sum of these numbers: "+sum);
    }
}
