The most basic Java learning route analysis, in view of this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Java is a more esoteric computer language, which is more widely used under the promotion of the Internet, and the number of students learning Java language is also increasing day by day, but many students in the beginner are a big problem, so how can the novice Java break through the first line of defense, master Java professional skills and become an elite in the it world? How to get started with the most basic Java rookies?

Introduction to the Java language:

Of course, the first thing to learn is the introduction and history of the language Java, which will help you understand the language Java better. Secondly, there are tools. In the process of learning this language, you will be exposed to a lot of tools, which is essential, but understanding contact first will give you a clearer understanding. When you know more about the tools, you can start our first Mini Program, that is, "helloworld".

The basic syntax of Java:

Secondly, we need to learn the basic syntax of Java, which includes basic data types, operators, if conditional judgments, and loop statements.

Basic data types include: byte (byte type), boolean (Boolean type), short (short integer), char (character type), int (integer type), float (floating point type), double (double precision type), long (long integer type). The most special of these should be Boolean, which has only two results: true or false.

Operators: arithmetic operator, assignment operator, comparison operator, logical operator, conditional operator.

If conditional judgment: this is used to judge and filter some parts of the statement that need to be judged.

Loop statement: consists of two parts: the body of the loop and the termination conditions of the loop. In many practical problems, there are many regular repetitive operations, so it is necessary to repeat some statements in the program. A group of statements that are repeatedly executed are called loop bodies, and whether they can be repeated or not determines the termination conditions of the loop.

The foundation of MySQL database:

The first is a general introduction of the database, followed by database tables, fields and field types, and then some basic statements of the database, such as select, insert, delete, update. Then a little bit deeper is the statement of the conditional query Where. Secondly, there are aggregate functions in the database such as max, min, avg, count. In depth, there are sorting queries and grouping queries, and finally federated queries.

JDBC operates the database:

First of all, it is also about the understanding of JDBC. Second, how to use JDBC to operate the database, and then know how to operate under the situation to understand some vulnerabilities injected into SQL statements, and then you can try to write a JDBCUtil and use it to manipulate the database. After that, you can continue to learn about transactions and batch commit. Then there is how to get the value of the auto-growing column.

The answer to the most basic Java learning route analysis question is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
