I have this for homework and I cannot figure out what I need to change to add spaces in between the output. I have tried everything I can think of can someone offer some help.
I included part of the code below.
Thanks

I am trying to set my output to
5 A, 1 B, 12 C, 3 D, 20 E

I currently get
5A1B12C3D20E
public static void main(String[] args) {
             RunLengthCompression RLC = new RunLengthCompression();
             String letter = "AAAAABCCCCCCCCCCCCDDDEEEEEEEEEEEEEEEEEEEE";
             System.out.printf(RLC.encode(letter));

Here it is. I did not post it before because I have someone using it in our class. I found my exact question and code from another assignment posted on another board from (I Think) someone in my class.
 public String encode(String source) {
        StringBuffer dest = new StringBuffer();
        for (int i = 0; i < source.length(); i++) {
            int runLength = 1;
            while( i+1 < source.length() && source.charAt(i) == source.charAt(i+1) ) {
                runLength++;
                i++;
