There are a lot of small partners who don't know where eclipse is downloaded and how to install it, so let me give you a demonstration.
The most common software for learning Java is Eclipse, which is not available immediately after Eclipse installation, and requires installing the JDK and setting up the environment. Here's a complete introduction to the entire process of eclipse from installation to use.
Eclipse installation
- 1
Download eclipse, suggest the official website download (completely free), go to the official website select "Eclipse IDE for Java EE developers", choose 32-bit or 64-bit according to your computer condition
- 2
Click "Download" to skip to the next page, and then click here to download it directly.
- 3
Download down is a compressed package, directly decompression, no installation. However, Eclipse is not open at this point, and the next step is to install the JDK setup environment.
