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
  */
  
}

Example 3: read int java

import java.util.Scanner;

public class Demo {

    public static void main(String[] args) {

        /* This reads the input provided by user
         * using keyboard
         */
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter any number: ");

        // This method reads the number provided using keyboard
        int num = scan.nextInt();

        // Closing Scanner after the use
        scan.close();
        
        // Displaying the number 
        System.out.println("The number entered by user: "+num);
    }
}
