Thread: ERROR - The method setTypeface(Typeface, int) is undefined for the type String

this is my code so far, i don't think it accepts the variable 'count' from the other class, but it keeps coming up with this error under
setTypeFace.

package com.example;
 
import java.text.SimpleDateFormat;
import java.util.Date;
import android.graphics.Typeface;
import android.view.View;
 
public class Message extends ChatApplication{
 
	@Override
	public String toString() {
		return timeFormat.format(time) + "\n" + sender + text + count;
	}
 
	Date time = new Date();
	SimpleDateFormat timeFormat = new SimpleDateFormat ("HH:mm");
 
	private String text;
	private String sender = "Carla: ";
	public int count;
 
	public void button(){
		if(count==0){
			text.setTypeface(Typeface.DEFAULT,Typeface.NORMAL);
		}
		else if (count == 1){
			text.setTypeface(Typeface.DEFAULT,Typeface.ITALIC);
		}
		else if (count == 2){
			text.setTypeface(Typeface.DEFAULT,Typeface.BOLD);
		}
	}
 
	public Message(String text) {
		super();
		this.text = text;
	}
 
	public String getText() {
		return text;
	}
 
	public Message(int count) {
		super();
		this.count = count;
	}
 
	public int getCount() {
		return count;
	}
 
 
}

no, i didn't think i needed a method for it, i've used this code before and it's worked fine like this !
