The ease of use of eclipse

As a beginner of Java, to learn a lot of things, especially when they do not have a computer foundation, to increase their burden of not only learning new things, but also include the heavy task of memory.

In the beginning, we configured the Java Development environment JDK for our computer. We can then write the source code in the text document that conforms to the structure arrangement and conforms to the syntax requirements. After that, the text file name is changed to the same name as the class name, and the file suffix. txt is changed to. Java, so that we have a copy of our own Java source file. After that, we open the Windows Command Window cmd, and in the. Java directory, use the Javac command to compile the. java file into a. class bytecode file. Finally, run the generated. Class bytecode file from the command line with the Java command. So we're done with a more complete Java program development process.

The process of making Java files Run is cumbersome enough to be difficult to remember. Moreover, some Java keywords do not remember, do not remember, the beginner stage needs to do some simple programming exercises, there is no solution?

The answer is yes, that's the Gospel for Java Developers: Eclipse Software.

The Eclipse software is a Java developer trusted by most Java users and is a free software. You only need to configure the development environment and then install the software to perform Java software development, and can greatly simplify the tedious development process described above.

First, Eclipse has the ability to instantly alert: When writing Java code, if there is a syntax error, eclipse will compile the syntax of the Java code in real time and find some errors that do not conform to the syntax rules, with hints given in the error, Greatly avoids the error of writing code without knowing what happens.

Second, Eclipse has the ability to compile on the fly: Eclipse has a virtual machine that contains class recognizers and interpreters, and after writing the Java source code and saving it, the Java file is recognized in eclipse to automatically generate a. class file that can run on the Eclipse platform. Omitted the tedious steps we ran in the Windows Command window. Greatly improves the development efficiency of Java programs.

In addition, Eclipse has a common lexical association function: As a Java beginner, you may have a lot of keywords do not remember, or just remember a part, enter the first few letters of the keyword, using the alt+/combination hotkey, you can let eclipse Lenovo common words, Just select the one in the candidate list, and Eclipse automatically inserts the directory where the class is entered when this is a Java-already-existing class.

In short, efficient work is based on the use of good tools under the premise, with good, with cooked eclipse this tool, so that the development of the program more than twice!
