Android programming is basically all Java. If you want to develop apps first you must first have knowledge of core java. Also having a knowledge of getters and setters, Array lists, Lists, classes and object are some of the important topics in Java for android. Also have a knowledge of classes such as Bundle, Intents which are specifically used for android. Trust me, there are many classes for android which you must be well aware of. Now comming to the question, you can start developing apps if you know abit of Java. That solely depends upon what you want to build. Some apps that are static needs a bit of programming and needs more of designing(XML). While some other apps that you want to build may need more advanced programming like network requests and many more. And now comming to the other part, say you have an idea in mind, you can search for similar projects study what do you need for that specific feature in you app and how can you achieve it. Let's say you want you app to perform network requests then find out how to do network requests. Then learn about that library. And then implement it in your app. Trust me there are lot of help available in the internet. Also my advice would be, Have a knowledge of core Java and then start building some basic apps with some basic features. Look over in the internet and then add some features to it. That's how you will learn. That's all. And good luck for you app. :) read less

public class X { public static void main(String [] args) { X x = new X(); X x2 = m1(x); /* Line 6 */ X x4 = new X(); x2 = x4; /* Line 8 */ doComplexStuff(); } static X m1(X mx) { mx = new X(); return mx; } } After line 8 runs. how many objects are eligible for garbage collection?
Only one. After line 8 the original object referred to by x2 is dereferenced and ready for garbage collection. In m1(), mx ignores the object passed as argument and refers to a new object which is returned.
