Unable to print the array method that returns an array

Question

public class ReturnAtrray {
     public static void main(String[] args) {
          int[] b= {1, 3, 5};
          System.out.println(incrementArray(b,2));
     public static int[] incrementArray(int [] a, int increment)
          int[] tmp = new int[a.length];
          for(int i = 0; i <a.length; i++ )
               tmp= tmp[i] + increment;
          return tmp;     

Answer 1

You are correct: Java is always pass by value. In the case of an array it is a reference to the array that is passed by value. This means that there is a way to increment the array values "in place". As an alternative to what you are doing now consider:
// untested
public class ReturnAtrray {
    public static void main(String[] args)
        int[] b= {1, 3, 5};
        incrementArray(b,2);
        for(int i = 0; i < b.length; i++)
            System.out.print(b[i] + " ");
    public static void incrementArray(int [] a, int increment)
        for(int i = 0; i <a.length; i++)
            a[i] = a[i] + increment;
}
