First, a primer In general, it is better to reuse an object than to create a new object of the same functionality every time you need it, especially if the object is immutable and can always be reused. Reusing objects plays an important role in program performance. Second, reuse immutable objects For immutable classes that provide both static factory methods and constructors, you can often use static factory methods instead of constructors to avoid

of an element in an array that matches the COUNTRY_ID key value, and if such an element exists in the array, the country_name is fetched from the array withoutTo perform a lookup query. If there is no such element, then a lookup query is performed and the results are stored as a new element in the array. You also need to understand that this technique is well suited for different statements with very few key values, in this case, the less the number of unique values in the country_id column, th

In programming development, the memory footprint is the reality that we often face, the direction of the usual memory tuning is to minimize the memory footprint. This avoids the creation of unnecessary objects as an important aspect.Android devices don't have enough memory like a PC, and a single app consumes less memory. So avoiding the creation of unnecessary objects is especially important for Android development.This article introduces some common scenarios and methods to

For each programmer, the fault is hanging on the head of the Damocles sword, are afraid to avoid, how to prevent failure is every programmer is struggling to find a solution to the problem. For this problem, we can from the requirements analysis, architecture design, code writing, testing, code review, on-line, online service operations and other perspectives to give their own answers. I combine my two years of limited internet back-end work experienc

Objective As you assign more objects to the app, you have to implement regular garbage collection, which can lead to a small cotton phenomenon in the user experience. Concurrent garbage processors are introduced in Android 2.3, but should always avoid unnecessary work, so you should avoid creating object instances when you don't need to. In the programming development, the memory occupies is we often to f
