New to Java

Hi, I am very new this and could sue some help..

import java.util.*;

public class CarSort
{
public static void main(String[] args)
{

final int ARR_SIZE = 30;

final boolean DEBUG = true;

final String SENT_DBASE = "EndDatabase";

final String SENT_SEARCH = "EndSearchKeys";

Car[] carArr = new Car[ARR_SIZE];

Car car1;

Scanner scan = new Scanner(System.in);

String
make;

int
year,
numCars,
pos;

double price;


numCars = 0;
make = scan.next();

if(DEBUG)
System.out.println("\nDB make = " + make);

while(!make.equals(SENT_DBASE))
{


if(!scan.hasNextInt())
{
System.out.println("ERROR1: no nextInt.\nStop!");
System.exit(0);
}
year = scan.nextInt();

if(DEBUG)
System.out.println("DB year = " + year);

if(!scan.hasNextDouble())
{
System.out.println("ERROR2: no nextDouble.\nStop!");
System.exit(0);
}
price = scan.nextDouble();

if(DEBUG)
System.out.println("DB price = " + Car.twoDecPl.format(price));



car1 = new Car(make, year, price);
numCars++;
carArr[numCars - 1] = car1;

make = scan.next();

if(DEBUG)
System.out.println("DB make = " + make);

}

private static void selectionSort(double[] dA, int n)
{
double temp;

int posMax;

for(int i = n - 1; i > 0; i--)
{
posMax = 0;
for(int j = 1; j <= i; j++)
if(dA[j] > dA[posMax])
posMax = j;

temp = dA[posMax];
dA[posMax] = dA;
dA[i] = temp;

}

}

printData(carArr, numCars);

make = scan.next();

if(DEBUG)
System.out.println("\nSearch, make = " + make);

while(!make.equals(SENT_SEARCH))
{
if(!scan.hasNextInt())
{
System.out.println("ERROR3: no nextInt #2.\nStop!");
System.exit(0);
}
year = scan.nextInt();

if(DEBUG)
System.out.println("Search, year = " + year);

if(!scan.hasNextDouble())
{
System.out.println("ERROR4: no nextDouble.\nStop!");
System.exit(0);
}
price = scan.nextDouble();

if(DEBUG)
System.out.println("Search, price = " +
Car.twoDecPl.format(price));



car1 = new Car(make, year, price);
System.out.println("\nSearch key =" + car1);


pos = seqSearch(carArr, numCars, car1);

if(pos >= 0)
System.out.println("This vehicle was found at index = " + pos);
else
System.out.println("This vehicle was not found in the database.");

make = scan.next();

if(DEBUG)
System.out.println("\nSearch, make = " + make);

}


}


// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

private static void printData(Car[] carArr, int numCars)
{

System.out.println("\nPrint out the database.");

for(int j = 0; j < numCars; j++)
System.out.println(carArr[j]);
}


// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

private static int seqSearch(Car[] carArr, int numCars, Car key)
{
for(int j = 0; j < numCars; j++)
if(carArr[j].equals(key))
return j;

return -1;

}


}

This code is giving an illegal start error on private static void selectionSort(double[] dA, int n), So can someone tell me (and also explain why) how to fix this?
