    Default Beginner Array Problem. Swapper

    SOLVED!





    This is what i have and I am not sure what i am doing wrong. It keeps giving me errors!

    public class Swapper
    {
    public static void main(String[] args){
       public void swapFirstAndSecondHalf(int[] values)
       {
          int[] a = {1,2,3,4,5};
    	  int k = 0;
    	  int temp = 0;
    	  while(k < a.length/ 2)
    	  {
    	  temp = a[k];
    	  a[k] = a[a.length -1-k];
    	  a[a.length-1-k] = temp;
    	  k++;
    	  }
     
     
     
     
       }
       // This method is used to check your work
       public int[] check(int[] values)
       {
          swapFirstAndSecondHalf(values);
          return values;
       }
    }
    }

    Any help would be greatly appreciated!

    Hint - don't put methods inside of methods. main() is a method. swapFirstAndSecondHalf() is a method.

    Try moving the method outside of the {}s that surround the code for the main() method.
    You may not need a new class.
    If you don't understand my answer, don't ignore it, ask a question.

    I am not sure what you mean. Should i write the code where the main method has nothing in it and then separate it?
    thank you Norm

    To correct the compiler error, make sure that no methods are defined inside of other methods.
    Make that change, get a clean compile and THEN write code for the main() method.
    One step at a time.
