String的compareTo方法底层代码

以下是java中String的compareTo方法底层代码

 public int compareTo(String anotherString) {int len1 = count;int len2 = anotherString.count;int n = Math.min(len1, len2);char v1[] = value;char v2[] = anotherString.value;int i = offset;int j = anotherString.offset;if (i == j) {    int k = i;    int lim = n + i;    while (k < lim) {char c1 = v1[k];char c2 = v2[k];if (c1 != c2) {    return c1 - c2;}k++;    }} else {    while (n-- != 0) {char c1 = v1[i++];char c2 = v2[j++];if (c1 != c2) {    return c1 - c2;}    }}return len1 - len2;    }
