用Arrays類截取路徑

import java.util.Arrays;
import java.util.stream.Collectors;

public class Test {
    public static void main(String [] args) {
        String path = "com/it/dao";
        System.out.println(Test.splitPath(path));
    }

    public static String  splitPath(String path) {
        String[] split = path.split("/");
        String secPath = Arrays.stream(split, 1, split.length).collect(Collectors.joining("/"));
        return secPath;
    }
}

// 結果：it/dao
