Java statement with example

I have encountered in this statement(the line after "**") which looks like an if else. I would be happy if someone can explain me what is that means.

boolean ascending = true;
    for (int i = 1; i < data.length; i++) {
        **boolean goingup = data[i] == data[i - 1] ? ascending : data[i]>= data[i - 1];**

In addition, I would like to hear some advises how to search this kind of questions online, instead of make queries.

thanks :)
