用任何字母替换字符串中的字符

Question

我正在寻找一种将通配符字符添加到字符串的方法，这样我就可以从近似匹配项中进行搜索，所以如果我在我的字符串列表中搜索单词 "b*ke"（其中 * 是通配符），我会得到 {bake, bike, byke, boke} 回来，这可能在 java 吗？

Answer 1

您已找到您需要的"regular expressions"。

import java.util.regex.Matcher;
import java.util.regex.Pattern;

final String regex = "b[a-z]{1}ke";
final String string = "bake, bike, byke, boke";

final Pattern pattern = Pattern.compile(regex);
final Matcher matcher = pattern.matcher(string);

while (matcher.find()) {
    System.out.println("Full match: " + matcher.group(0));
    for (int i = 1; i <= matcher.groupCount(); i++) {
        System.out.println("Group " + i + ": " + matcher.group(i));
    }
}

Answer 2

一切都是真的

    System.out.println("bike".matches("b.ke"));
    System.out.println("bake".matches("b.ke"));
    System.out.println("b1ke".matches("b.ke"));

    System.out.println("b123ke".matches("b.+ke"));
    System.out.println("b[wait_for_it]ke".matches("b.+ke"));
