how to do user input mix of numbers and letters using JOptionPane

[broception]

What i have so far.
I'm trying to get it to where i can enter anything for example: lajflho142323kj lkhaf
but the program blows up if i do a mix of letters and numbers

import javax.swing.JOptionPane;

public class morePractice {

	public static void main(String[] args) {
		String str;
		int num1;
		
		str=JOptionPane.showInputDialog("Enter phrase");
		num1=Integer.parseInt(str);
		
	
	}

}

[r035198x]

num1=Integer.parseInt(str);

converts the input to an int which fails if the input is not an int, like for example lajflho142323kj lkhaf.
If you want the input to accept the mixture then don't do Integer.parseIn t
