Inputting the correct condition for a for loop

I am trying to write a small program dealing the earthquakes and magnitudes.

When the program is run, it asks the user to input a number for how many earthquakes the user wants to submit magnitudes for. Depending on the response, the program then prompts the user to enter a magnitude for each earthquake. I have written the following code below but am having trouble with the for loop.

Obviously in the for loop, putting i <= numberOfEarthquakes disallows the program from compiling correctly. What is a simple way to give i a condition that correlates to the inputted number from the user. Much thanks.

(this is a smaller part of a larger program that I am hoping to write)

import java.util.*;

public class Earthquakes {

    public static void main(String[] args) {

        Scanner console = new Scanner(System.in);
        System.out.print("How many magnitudes will you enter? ");
        String numberOfEarthquakes = console.next();

        for (int i = 1; i <= numberOfEarthquakes; i++) {
            System.out.print("Enter magnitude for earthquake " + i);
            String magnitudeOfEarthquake = console.next();
        }
    }
}

Convert your numberOfEarthquakes from String to Integer. Use Integer.parseInt(numberOfEarthquakes) to convert String to Intger.

Make this String numberOfEarthquakes = console.next(); to int numberOfEarthquakes = console.nextInt();

You can not compare String with int.
