Incompitable types? int cannot be identidied

Question

How can I fix this problem here:

Error:(8, 43) java: incompatible types: java.lang.String cannot be converted to int

My code:

import jdk.internal.util.xml.Input;

import java.util.*;    
public class HelloWorld { //this is a comment
    public static void main(String[], args) {
        Scanner input = new Scanner(System.in);
        System.out.println("Welcome");
        int grade = input.nextLine();

        if (grade > 60) {
             System.out.println("Admited");
        }
    }
}

It says it requires an integer, but it found a string.

Scanner.nextLine() returns a String, which cannot be type casted to an int primitive. https://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html — Fullstack Guy, Aug 23 '18 at 20:35

String is an Object, int is a primitive; they are not compatible. Use Integer.parseInt(String, 10); The "radix" will stop certain code analyzers from complaining. Note that a String that can't be parsed will result in an exception.

*The "radix" will stop certain code analyzers from complaining.* About what? – shmosel Aug 23 '18 at 20:43
Apparently, some code analyzers think that using the default radix is ambiguous or some such. I was annoyed the first time it happened. – Steve11235 Aug 24 '18 at 14:25
