Combining string array elements into one string

Question

Right, I have an string array called str which stores 1 character in each of its 16 elements. It gets this character from another array, strArray. Now, what I want to be able to do is to take all 16 elements and combine them into one string called keyString. Using the code below keyString only prints out the last character. The code is shown below:
for (x=0; x<16; x++) {
     str = new String[16];
     str[x] = "";
     str[x] += (strArray[(index+x)%16].charAt(strChar[x]));
     keyString = str[x];
       System.out.print(keyString);
}Any help would be very much appreciated.

Answer 1

your logic is wrong ; if you want to concatenate the content of the array, you have to loop (what you did), and concatenate keyString for each index, meaning:
keyString += str[x];you can also use a StringBuilder for such kind of operations
