How to return a specific element of an array

Question

I want to return odd numbers of an array yet Eclipse doesn t seem to accept my return array i   code  I think it requires returning a whole array since I set an array as a parameter to my method  As I said before  I need to pass an array and get a specific element of that array in return  Even if I make that array static  how do I return a single element   Edit   Alright then  here it is   public class newClass  public static void main String   args                int    newArray  new int  4       int    array    4 5 6 7        newArray 0    array 0  array 1  array 2  array 3       newArray 1    array 0  array 1  array 2  array 3       newArray 2    findOut array       public static int findOut  int    array3        int e1 0      int e2 0      for  int i 0  i lt array3 length  i                  if  array3 i  2  0                        e1  array3 i               array3 i  e1             return array3 i                      else                       e2  array3 i               array3 i  e2              return array3 i                              I know there are probably more than a few mistakes here but I m working on it and I m not only returning odd numbers  I also add them together

I want to return odd numbers of an array

If i read that correctly, you want something like this?

List<Integer> getOddNumbers(int[] integers) {
  List<Integer> oddNumbers = new ArrayList<Integer>();
  for (int i : integers)
    if (i % 2 != 0)
      oddNumbers.add(i);
  return oddNumbers;
}

You code should look like this   public int getElement int   arrayOfInts  int index        return arrayOfInts index       Main points here are method return type  it should match with array elements type and if you are working from main   - this method must be static also

Make sure return type of you method is same what you want to return  Eg        public int get int   r           return r 0            Note   return type is int  not int    so it is able to return int   In general  prototype can be  public Type get Type   array  int index        return array index

Edited   There are two reasons why it doesn t compile  You re missing a semi-colon at the end of this statement   array3 i  e1   Also the findOut method doesn t return any value if the array length is 0  Adding a return 0  at the end of the method will make it compile  I ve no idea if that will make it do what you want though  as I ve no idea what you want it to do
