【Idea】What does Process finished with exit code 0 mean?

When running a Java program in [Idea], after it runs successfully, the following statement appears. What does this mean?

即：Process finished with exit code 0

After Baidu translation, I found that it means the following:

Process finished with exit code 0 Process finished with exit code 0

The statement:

Indicates that your program has completed its normal execution and exited.

For exit code, it is applicable in most programming languages;

exit code 0 indicates that the program was executed successfully and exited normally;

Exit code 1 indicates that some problems or errors are encountered during the execution of the program, and it exits abnormally.
