Cause Analysis: JDK version does not match eclipse

such as JDK and Eclipse version numbers must be uniform, 64-bit is 64-bit, 32-bit is 32-bit.

The JDK version can be used with commands, cmd into the command window, and then enter Java-version to view the last line of version information.

If the eclipse version is too old, you will be prompted with the new JDK version, and you will need to replace the JDK version with the old version.

After you replace the JDK version, you need to re-unzip the Eclipse program to open it before the Eclipse program you unzipped needs to be removed.
