从数组分配到 Java 中的字符串列表

Question

Is there a way to get rid of buf ?

public Option(String opt) {
    String[] buf;
    buf = opt.split("=");
    key = buf[0];
    value = buf[1];
}

I thought of something like { key, val } = opt.split("="); as it would be possible in Perl, IIRC.

There is java.util.Scanner , which gives back one token at a time. But it's a lot harder to use than split , and in my experience not worth the trouble for problems simple enough to handle w/ split .
