As suggested by Richard, you can make the function return a class as follows:

Java

class ReturnResult {
    private double first;
    private double second;

    public ReturnResult (double first, double second) {
        this.first = first;
        this.second = second;
    }

    public double getFirst() {
        return first;
    }

    public double getSecond() {
        return second;
    }
}


private ReturnResult calculateBalance(double ammt, double balance){
    
	// do something

    return new ReturnResult(firstDouble, secondDouble);
}

public static void main(String[] args) {

	double ammt = ???;	// some double value
	double balance = ???;	// some double value	
    ReturnResult result = calculateBalance(ammt, balance);
	// do something
}

Create an array with the two values and return the array. Something like:
