Sending Email in Java getting error couldn't connect to host

Original Post ~ I am trying to send an email through java but I am getting an error that says it couldn't connect to host, port: smtp.gmail.com, 547; timeout -1;

I am trying to send it through gmail and I have imported two jar files, which are java mail api download – https://javaee.github.io/javamail/ java activation jar download – https://mvnrepository.com/artifact/javax.activation/activation/1.1.1

It takes forever to run and once it finally does finish it show that error.I would appreciate any help, even if it is just pointing me to a YouTube video or another post on this website. Thank you in advance.

Updated Post~ I had a comment saying to use 587 instead of 547 so I changed it but I am now getting an javax.mail.AuthenticationFailedException: Username and password not accepted error. I have googled and even looked on stack overflow and they say to change a setting in my google account but when I go to change it google is saying the setting is no longer available... it is the Less Secure app access. I will love any thoughts or direction on how to fix this problem. I am on a Mac if anyone thinks that could be causing a problem.
