Java - how to return two values from one method?

Below is the bit of code where the “high” and “low” values from the returns previously mentioned are getting called, r.getRainAt(high) and r.getRainAt(low). This is in the Main class. The method getRainAt is in a different class. I’m not allowed to change anything in the Main.java.

I should have mentioned that earlier, but does that change anything? Would one of the approaches in the references below still work?

   // Get and display the month with the highest rainfall.
        high = r.getHighestMonth();
        System.out.println(
                "The month with the highest amount of rain " + "is " + (high + 1) + " with "
                        + r.getRainAt(high) + " inches.");

        // Get and display the month with the lowest rainfall.
        low = r.getLowestMonth();
        System.out.println(
                "The month with the lowest amount of rain " + "is " + (low + 1) + " with "
                        + r.getRainAt(low) + " inches.");

I have tested getRainAt with separate if statements and made sure that they both worked to return the right element value to getRainAt(high) and getRainAt(low) when I returned each one at a time.
