You can use Scanner class
Import first :
import java.util.Scanner;
Then you use like this.
Scanner keyboard = new Scanner(System.in);
System.out.println(“enter an integer”);
int myint = keyboard.nextInt();
Side note : If you are using nextInt() with nextLine() you probably could have some trouble cause nextInt() does not read the last newline character of input and so nextLine() then is not gonna to be executed with desired behaviour. Read more in how to solve it in this previous question Skipping nextLine using nextInt.
You can use Scanner class like this:
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);
}
}
