In Java, if I am building a significant number of strings, is there any difference in performance in the following two examples?

StringBuilder sb = new StringBuilder();

for (int i = 0; i < largeNumber; i++) {
    sb.append(var[i]);
    sb.append('=');
    sb.append(value[i]);
    sb.append(',');
}

or

StringBuilder sb = new StringBuilder();

for (int i = 0; i < largeNumber; i++) {
    sb.append(var[i]).append('=').append(value[i]).append(',');
}

Thanks!
