使用多态性打印字符串匹配项

public interface MatchRule {
    void printMatch(String input);
}

public class ExactMatchRule implements MatchRule {
    @Override
    public void printMatch(String input) {
        System.out.println("Exact match: " + input);
    }
}

public class PartialMatchRule implements MatchRule {
    @Override
    public void printMatch(String input) {
        System.out.println("Partial match: " + input);
    }
}

public void printMatchingString(MatchRule rule, String input) {
    rule.printMatch(input);
}

public static void main(String[] args) {
    MatchRule exactMatchRule = new ExactMatchRule();
    MatchRule partialMatchRule = new PartialMatchRule();

    String input = "example string";

    printMatchingString(exactMatchRule, input);
    printMatchingString(partialMatchRule, input);
}
