    Question Weiszfeld’s Algorithms Help PLS

    Please help me. Where is wrong ?

    package Sezgisel;
     
    public class SezgiselAlgoritma1 {
     
    	public static void main(String[] args) {
     
    	double a[]={40.78,40.75,40.71,40.72,40.69,40.93,40.51,40.80,40.64, 41.07,41.03,41.05,40.51,40.69,40.88,40.40};
    	double b[]={30.40,30.40,30.36,30.38,30.62,30.48,30.29,30.75,30.54, 30.78,30.31,30.85,30.17,30.27,30.45,30.49};
    		//Rastgele değerler x=50 ve y=50 olarak verildi.
    		int x=50;
    		int y=50;
    		int literasyon=0;
    		double m,l;
    		double J=0;//Amaç fonksiyonu J fonksiyonudur.
    	do {
    			 double Toplam=0;
    			 for ( int i=0; i<16; i++){
    			 m(i)=1/sqrt(((x-a[i]))^2+((y-b[i]))^2);
    			 Toplam=Toplam+ m(i);
    			  }// 1. for end
    			 for (int i=0; i<16; i++){
    				 l(i)=m(i)/Toplam ;
    			 }//2. for end
    			 x=0; y=0;//Formüldeki ilk x ve y değerleri sıfırdır.
    			 for (int i=0; i<16; i++){
    				 x= x+ (l(i)*a[i]);
    				 y= y+ (l(i)*b[i]);
    			 }//3. for end
     
    			 for (int i=0; i<16; i++){
    			 J=J+ sqrt(((x-a[i]))^2+((y-b[i]))^2);
     
    			literasyon=literasyon+1;
    	}while (literasyon!=50);
    		System.out.println("Tesisin enlem değeri X=" + x + "ve boylam değeri Y=" + y + "'dir." );
     
    	 }
    		System.out.println("Amaç fonksiyonumuzun değeri Z=" + J);
     
    	}
     
    }

    Where is wrong ?
    Can you explain what the problem is?
    Post the program's output, explain what is wrong with it and show what it should be.

    The error messages do NOT show what lines they happened on. I don't think all those error messages are for the code at line 19. What code is on line 19?
    Can you use the javac compiler to compile the program to get compiler error messages?
    Your IDE's error messages don't say where the errors are.
