class Slogan {
	String phrase; // string description of slogan
    static int count; // slogan count    
    public Slogan(String phrase) {
    	this.phrase = phrase;
        count++;
    }
}

public class SloganCounter {
	public static void main(String[] args) {
    	Slogan slg1 = new Slogan("Live free or die!");
        Slogan slg2 = new Slogan("Don't worry, be happy!");
    
    	System.out.println("Slogans count: " + Slogan.count);
