    Default help with char

    I'm having trouble figuring this out
    this is assignment

    Write a program using a while-loop (and a for-loop) that asks the user to enter a string, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the string. (So, you will have two separate program codes, one using a while-loop and the other one using a for-loop.)

    Example:
    Enter a string: “Hello, JAVA is my favorite programming language.”
    Enter a character: e
    The number of times the specified character appears in the string: 3

    I don't even know where to begin Ive only got this

    import java.util.Scanner;
     
    public class letterCounter {
     
    public static void main(String [] args) {
     
    	Scanner sc = new Scanner(System.in);
     
    	System.out.println("Enter a string");
    	String myString = sc.nextLine();
     
    	System.out.println("Enter a letter");
    	String letter = sc.nextLine();
    	}
    }

    help please

    Look at the String class. It has several methods that could be used to look at individual characters in the String.
    Use a loop to get each character one at a time from the String.
    Use an if statement to compare each character against the one to search for and increment a counter on a match.
    If you don't understand my answer, don't ignore it, ask a question.
