that, you'll see the following interface.Similarly, you can set the project type, but since you are now creating a Module, you only have to choose one type.The 4 options below represent a different meaning: Android Library: Create a Module for the Android library. Import Existing Project: Importing another project as a Module, the imported project can be an Eclipse ADT project, or it can be a Gradle project (Gradle is just a project builder, which is also available in eclipse).

1. What is Spring?When I first approached Java, I wondered why everyone was talking about spring, as if Java was spring, and what was spring? In fact, he is a container frame, you can think of it as a toolbox, it can help you quickly Java development.2, how to use spring?Spring is especially easy to use, download the jar package, import the project, write the cor

in a text file, the rows and columns must be distinguished by a certain format, and the delimiters are indicated in hive. Hive uses a number of characters that are seldom present by default, and these characters generally do not appear as content in the record. The default row and column separators for Hive are shown in the following table. Separators Description \ n For a text file, each line is a record, so \ n to split the record

In the first play I explained the purpose of learning Python, mainly for the sake of self-improvement, then why I am interested in Python, what is the use of Python? This chapter is simply explained below.Python's use is very broad, and the code is very concise, not like Java, C and other languages, the variable declaration, call classes, libraries, functions and other cumbersome operations, and the code st

to move through memory, and QVector for data types that can only be moved using copy constructors and destructors, another set of algorithms is used. Because the latter consumes more, QVector it reduces the amount of extra memory that is allocated each time you go out of space.QHashis a completely different form. QHashThe internal hash list increases the power of 2 each time, and each time it is incremented, all data is reassigned to the new bucket, with the formula qHash(key) % QHash::capacity
