What is the difference between "throw" and "throws" keyword in Java? - Learn from here, How to persist data in an Android app? Code inside static block is executed only once: the first time you make an object of that class or the first time you access a static member of that class (even if you never make an object of that class). - Learn from here, What is obfuscation? It is also a good practice to annotate overridden methods with @Override to make the compiler be able to notify you if child is, indeed, overriding parent's class method during compile-time. Why use suspend function in Kotlin Coroutines? A list of top android interview questions and answers: 1) What is Android? - Learn from here, How does the OutOfMemory happens? - Learn from here, When to use defer operator of RxJava? - Learn from here, What is Coroutine Context? - Learn from here, How are Timer, Delay, and Interval operators used in RxJava? Why do we prefer Framelayout for Fragments? For example: In Java all primitives and objects are passed by value, meaning that their copy will be manipulated in the receiving method. - Learn from here and here, How to run parallel tasks in Java or Android, and get callback when all complete? While child class can override a static method with another static method with the same signature (return type can be down-casted), it is not truly overridden - it becomes "hidden", but both methods can still be accessed under right circumstances (see question about overloading/overriding above). But for methods, we need to call it explicitely. It just compares neighbouring elements and if the one that precedes the other is smaller - it changes their places. When implemented correctly, it can be a significant number of times faster than its' main competitors. How is Binary Search Tree different from Binary Tree? Draw a simple basic design you follow to make an android application(folder structure, methods, variables), Why services preferred over Broadcast receiver for background applications. Can we identify users who have uninstalled our application? - Learn from here, Can you a create custom view? and then will create and return another object with value "HELLO, WORLD!". - Learn from here, What are the metrics that you should measure continuously while android application development? * Parcel overloaded constructor required for, * Parcelable implementation used in the CREATOR. Please raise a PR and contribute. - Learn from here, How do you troubleshoot a crashing application? - Learn from here, How to check if Software keyboard is visible or not? So over one iteration over the data list, it is guaranteed that. - Learn from here, What is the difference JVM, DVM and ART?
