Android - opening activity from class name

ClassLauncher.java

package org.sgnn7.util;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;

public class ClassLauncher {
	private final Context context;

	public ClassLauncher(Context context) {
		this.context = context;
	}

	public void launchActivity(String className) throws Exception {
		Intent intent = new Intent(context, getActivityClass(className));
		context.startActivity(intent);
	}

	private Class<? extends Activity> getActivityClass(String target) throws Exception {
		ClassLoader classLoader = context.getClassLoader();

		@SuppressWarnings("unchecked")
		Class<? extends Activity> activityClass = (Class<? extends Activity>) classLoader.loadClass(target);

		return activityClass;
	}
}

What is target parameter in getActivityClass method?

private Class<? extends Activity> getActivityClass(String target) throws Exception {
ClassLoader classLoader = context.getClassLoader();
