eli5: When fruit ripens it gets sweeter. Does that mean the sugar content increases? If so, how does this work?

Unripe fruit has a lot of starches. Starches are technically complex sugars but they don't taste sweet. As the fruit ripens the starches are broken down into simple sugars. These simple sugars are sweet tasting.
