You better use your JJJ class as the class loader and check that the class you try to load is in the classpath.

public class JJJ {

  public static void main(String[] args){

    ClassLoader classLoader = JJJ.class.getClassLoader();

    try {
      Class aClass = classLoader.loadClass("com.load.data.JJJ");

    } catch (ClassNotFoundException e) {
      e.printStackTrace();
    }

  }
}

The package structure must be reflected in the directory structure. If the class loader loads from C:\Users\user\\Desktop\jk the class must actually be stored here:

C:\Users\user\Desktop\jk\com\load\data\JJJ.class
