如果您想搜索不完全匹配的内容,我会尝试ArrayList
在MyAppRecord
哪里
public class MyAppRecord {
private String record;
private int deviance;
}
并为每条记录获取要查找的字符串的偏差:
public static int getLevenshteinDistance (String s, String t) {
if (s == null || t == null) {
throw new IllegalArgumentException("Strings must not be null");
}
int n = s.length(); // length of s
int m = t.length(); // length of t
if (n == 0) {
return m;
} else if (m == 0) {
return n;
}
int p[] = new int[n+1]; //'previous' cost array, horizontally
int d[] = new int[n+1]; // cost array, horizontally
int _d[]; //placeholder to assist in swapping p and d
// indexes into strings s and t
int i; // iterates through s
int j; // iterates through t
char t_j; // jth character of t
int cost; // cost
for (i = 0; i<=n; i++) {
p[i] = i;
}
for (j = 1; j<=m; j++) {
t_j = t.charAt(j-1);
d[0] = j;
for (i=1; i<=n; i++) {
cost = s.charAt(i-1)==t_j ? 0 : 1;
// minimum of cell to the left+1, to the top+1, diagonally left and up +cost
d[i] = Math.min(Math.min(d[i-1]+1, p[i]+1), p[i-1]+cost);
}
// copy current distance counts to 'previous row' distance counts
_d = p;
p = d;
d = _d;
}
// our last action in the above loop was to switch d and p, so p now
// actually has the most recent cost counts
return p[n];
}
}
将其保存到您的 -object 中MyAppRecord
,最后按其-objects 对您ArrayList
进行排序。deviance
MyAppRecord
请注意,这可能需要一些时间,具体取决于您的记录集。请注意,无法通过搜索 dog 来判断 dogA 或 dogB 是否位于列表中的某个位置。
阅读 Levensthein 距离,了解它的工作原理。您可能会想到对可能长/短的字符串进行排序,以获得适合您可能拥有的阈值的距离。
也可以将“足够好”的结果复制到不同的ArrayList
