I am unable to understand what is wrong in my java code please help!
import java.util.Scanner;
class Solution {
public static void main(String args[]){
double t,mincost=-1,p=0;
int cas=0;
double[][] c=new double[50][2];
Scanner sc=new Scanner(System.in);
t=sc.nextInt();
double A[]=new double[2];
double B[]=new double[2];
double C[]=new double[2];
double D[]=new double[2];
while(cas!=t){
int n=sc.nextInt();
for(int i=0;i<n;i++){
c[i][0]=sc.nextInt();
c[i][1]=sc.nextInt();
}
for(int i=0;i<n;i++){
A[0]= c[i%n][0];
A[1]= c[i%n][1];
B[0]= c[(i+1)%n][0];
B[1]= c[(i+1)%n][1];
C[0]= c[(i+2)%n][0];
C[1]= c[(i+2)%n][1];
D[0]=c[(i+3)%n][0];
D[1]=c[(i+3)%n][1];
p=area(A,B,C,D);
p*=2;
if(i==0) mincost=p;
else if(p<mincost) mincost=p;
}
System.out.println("Case #"+(cas+1)+":"+(long)mincost);
cas++;
}
}
static double area(double A[],double B[],double C[],double D[]){
double l1=A[0]*B[1]+B[0]*D[1]+D[0]*A[1];
double r1=A[1]*B[0]+B[1]*D[0]+D[1]*A[0];
double t1=Math.abs((l1-r1)/2);
double l2=B[0]*D[1]+D[0]*C[1]+C[0]*B[1];
double r2=B[1]*D[0]+D[1]*C[0]+C[1]*B[0];
double t2=Math.abs((l2-r2)/2);
return t1+t2;
}
}
