Java code for Distance formula from input (1,2)(2,3)


Java code for Distance formula from input (1,2)(2,3)

To fix the issue you can do Yes, you should use regular expressions to take numbers from text. Something like this:
code :
String input = br.readLine();
// Compile you pattern with two groups to capture each num
Pattern pattern = Pattern.compile("\\((\\d+(\\.\\d+)?),(\\d+(\\.\\d+)?)\\)");
// Match your input
Matcher matcher = pattern.matcher(input);
// If your input matches to pattern you want, then you take numbers
if (matcher.find()) {
    double x = Double.parseDouble(matcher.group(1);
    double y = Double.parseDouble(matcher.group(3);
    //... Other code you need
}

will help you You're trying to take the square root of a negative number. Add the squares, don't subtract them.
Also, negating y - other.y is unnecessary, though harmless. value2 is the same as (-value)2 for all numbers.
code :
System.out.println("D = " + Math.sqrt(Math.pow(x - other.x, 2) + Math.pow(y - other.y, 2)));
//                                                            ^^^

around this issue First I think you would need some way to enter the values of each variable.
code :
public void setX1(double x1) {
   this.x1=x1;
}
public DistFormula(double x1, double x2, double y1, double y2) {
   this.x1=x1;
   this.x2=x2;
   this.y1=y1;
   this.y2=y2;
}
public double calculate() {
   return Math.sqrt(Math.pow((x2 - x1), 2) + Math.pow((y2 - y1), 2));
}
DistFormula newFormula = new DistFormula();
newFormula.setX1(10.1);
newFormula.setY1(18.2);
newFormula.setX2(12.9);
newFormula.setY2(17.5);

double answer=newFormula.calculate();
System.out.println("Distance between coordinates: " + answer); 
DistFormula newFormula = new DistFormula(10.1,18.2,12.9,17.5);

double answer=newFormula.calculate();
System.out.println("Distance between coordinates: " + answer);

wish help you to fix your issue I'm struggling to understand the normalisation process of the 8 point algorithm. I am referring this code in MATLAB which I'm not able to run since I don't have matlab. , Okay, let's go through this
code :
centroid = mean(x, 2);
dist = sqrt(sum((x - repmat(centroid, 1, size(x, 2))) .^ 2, 1));
repmat(centroid, 1, size(x, 2))
x1 = [20, 30, 40, 50, 60, 30, 20, 40];
y1 = [12, 34, 56, 78, 89, 45, 90, 29];
x = [ x1 ; y1 ];
centroid = mean(x, 2);
dist = sqrt(sum((x - repmat(centroid, 1, size(x, 2))) .^ 2, 1));
dist'

ans =

      25.4033093316599
x1 = np.array([20, 30, 40, 50, 60, 30, 20, 40])
y1 =  np.array([12, 34, 56, 78, 89, 45, 90, 29])
x = np.column_stack((x1,y1))
centroid = np.mean( np.transpose( x ) )
dist = [ np.sqrt( np.sum( np.square( v - centroid ) ) ) for v in x ]
dist

To fix this issue You should be specifying double precision for all your exponent calculations:

I hope this helps . You can use the ScriptEngineManager to evaluate mathematical expressions using the javascript engine.
ofc. you would need to replace "x" with it's substitute first:
code :
String formula = "x/2 + x";
Integer X = 6;

ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine eng = mgr.getEngineByName("JavaScript");

System.out.println(eng.eval(formula.replace("x", X)));
