java版oa源代码 java compareto源码

private final char value[];//value是字符数组
public int compareTo(String anotherString) {
int len1 = value.length;
int len2 = anotherString.value.length;
int lim = Math.min(len1, len2);
char v1[] = value;
char v2[] = anotherString.value;
int k = 0;
while (k < lim) {
char c1 = v1[k];
char c2 = v2[k];
if (c1 != c2) {
return c1 - c2; //返回ASC码之差，码越大，返回为正值；ASC码小，则返回负值；
}
k++;
}
return len1 - len2; //若前面的字符串都相同，则字符串长的为大
}
compareTo方法依次字符串中的字符的ASC码比较比是
