Can't public static?

package main;

import java.io.IOException;

import org.newdawn.slick.opengl.Texture;
import org.newdawn.slick.opengl.TextureLoader;
import org.newdawn.slick.util.ResourceLoader;

public class Textures {

    public static Texture loadPNG(String path) throws IOException {
        return TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream(path));
    }


    public static boolean loadTextures() {
        try {
            final Texture STONE = loadPNG("main\\textures\\stone.png"); // This line here I can't do public static final...

        } catch (IOException e) {
            return false;
        }
        return true;
    }
