/opt/soft/java/bin/java is not executable

As an AI language model, I'm unable to access your system and analyze why the specified file is not executable. However, here are some possible reasons and solutions:

1. Permissions: Check if the file has executable permissions. You can use the command `ls -l /opt/soft/java/bin/java` to view the permissions. If it doesn't have executable permissions, you can use the command `chmod +x /opt/soft/java/bin/java` to make it executable.

2. Corrupted file: If the file is corrupted, it may not be executable. You can try downloading and installing Java again.

3. Wrong architecture: If the Java version you installed is not compatible with your system architecture, it may not be executable. Make sure you install the correct version for your system.

4. Missing dependencies: Java may have dependencies that are not installed on your system. Try installing the required dependencies.

5. File system error: There may be errors in the file system that prevent the file from being executed. Try running a file system check using the `fsck` command.
