how to use scanner class to read integer in java code example
Example 1: read integer input java
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int a = Integer.parseInt(br.readLine());
Example 2: read int from keyboard java
import java.util.Scanner;
public class Main{
public static void main(String args[]){
Scanner scan= new Scanner(System.in);
//For string
String text= scan.nextLine();
System.out.println(text);
//for int
int num= scan.nextInt();
System.out.println(num);
}
/*Is better to create another instance of Scanner if you have to use both nextline
and nextInt because they can conflict each other
*/
}
