有找到好办法。写出来也不算太麻烦。没有考虑general的solution,也没有考虑CDData
和comment.对我们这个app应该足够了。

The code below is the most efficient: (better than calling contains and
equals):
boolean xyzThere(String str) {
char next[] = new char[] {'x', 'y', 'z'};
int state = 0;
for (int i = 0; i < str.length(); i ++) {
char ch = str.charAt(i);
switch (status) {
case 0:
if (ch == '.') {
state = -1;
} else if (ch == 'x') {
state = 1;
}

发帖数: 1089 | 4 correct some typo:
boolean xyzThere(String str) {
char next[] = new char[] {'x', 'y', 'z'};
int state = 0;
for (int i = 0; i < str.length(); i ++) {
char ch = str.charAt(i);
switch (state) {
case 0:
if (ch == '.') {
state = -1;
} else if (ch == 'x') {
state = 1;
}
break;
case -1:
if (ch != '.') {
state = 0;
}
break;

s = ""是怎么回事想明白
s.charAt(0)这个整个内存逻辑怎么实现想出来再说
arraylist的实现要在这个基础上复杂两层 |
