What is the best way to structure a group of variables that have a group of variables that have a group of variables and so on?

I'm creating a Java program which calculates rates. The rate has a season which has its peaks and those peaks have their own hours and prices. I was thinking of doing nested classes, but there's got to be a better way that I'm just not thinking about it right?

Variables that I need to store:

Rate
	Summer
		peak
			hours
			price
		midpeak
			hours
			price
		off-peak
			hours
			price
	Non-summer
		peak
			hours
			price
		midpeak
			hours
			price
		off-peak
			hours
			price

Here is an approach:

class BaseRate {
int hours;
int price;
public BaseRate(int hours, int price) {
this.hours = hours;
this.price = price;
}
}
class SeasonalRate {
BaseRate peakRate;
BaseRate midPeakRate;
BaseRate offPeakRate;
public SeasonalRate(BaseRate peakRate, BaseRate midPeakRate, BaseRate offPeakRate) {
this.peakRate = peakRate;
this.midPeakRate = midPeakRate;
this.offPeakRate = offPeakRate;
}
}
class AnnualRates {
SeasonalRate summerRate;
SeasonalRate winterRate;
public AnnualRates(SeasonalRate summerRate, SeasonalRate winterRate) {
this.summerRate = summerRate;
this.winterRate = winterRate;
}
public static void main(String[] args) {
BaseRate peakWinterRateFor2019 = new BaseRate(1, 3);
BaseRate midPeakWinterRateFor2019 = new BaseRate(1, 3);
BaseRate offPeakWinterRateFor2019 = new BaseRate(1, 3);
BaseRate peakSummerRateFor2019 = new BaseRate(1, 3);
BaseRate midPeakSummerRateFor2019 = new BaseRate(1, 3);
BaseRate offPeakSummerRateFor2019 = new BaseRate(1, 3);
SeasonalRate winterRateFor2019 = new SeasonalRate(peakWinterRateFor2019, midPeakWinterRateFor2019, offPeakWinterRateFor2019);
SeasonalRate summerRateFor2019 = new SeasonalRate(peakSummerRateFor2019, midPeakSummerRateFor2019, midPeakWinterRateFor2019);
AnnualRates ratesFor2019 = new AnnualRates(summerRateFor2019, winterRateFor2019);
}
}
