How To Compute Relative Strength Index (RSI) using Java?

To compute the Relative Strength Index (RSI) using Java, you can follow the steps below:

1. Define a method that calculates the RSI:
 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 ``` ```public static double calculateRSI(double[] prices, int period) { double sumGain = 0; double sumLoss = 0; for (int i = 1; i < period; i++) { double priceDiff = prices[i] - prices[i - 1]; if (priceDiff > 0) { sumGain += priceDiff; } else { sumLoss -= priceDiff; } } double avgGain = sumGain / period; double avgLoss = sumLoss / period; double rs = avgGain / avgLoss; double rsi = 100 - (100 / (1 + rs)); return rsi; } ```

1. Call the calculateRSI method with an array of prices and the period for which you want to calculate the RSI:
 ```1 2 3 4 5 ``` ```double[] prices = {50.0, 55.0, 60.0, 65.0, 70.0, 75.0, 80.0, 85.0, 90.0, 95.0}; int period = 14; double rsi = calculateRSI(prices, period); System.out.println("RSI: " + rsi); ```

1. Run your Java program to calculate and display the RSI for the given prices and period.

Please note that this is a simplified example of calculating the RSI and may need to be adjusted based on your specific requirements or data sources.
