Counting how many letters and numbers

[broception]

I'm trying to count how many letters and how many numbers are in a user input string. For example:
Number01: should display
2 numbers
6 letters

So far, I've counted how many letters there are but I don't know how to add numbers to the string.

import javax.swing.JOptionPane;

public class morePractice {

	public static void main(String[] args) {
		String str;
		int num1;
		int total=0;
		char letter;
		int totalNum=0;
		
		str=JOptionPane.showInputDialog(null,"Enter phrase");
		
		for(int i=0;i<str.length();i++){
			letter=str.charAt(i);
			if(letter>='A'&&letter<='Z' || letter>='a'&&letter<='z'){
				total++;
			}
			
		}
		JOptionPane.showMessageDialog(null,"There are " + total + " letters");
		
	}

}

Do the same thing, except for the characters '0' to '9'
