如何在Java中串联字符串数组

抛开诸如检查数组是否为的事情null，您可以为其创建通用方法，并在您的特定情况下使用它，如下所示：

    public String[] concatAll(String[] jobsA, String[] jobsB, String[] jobsC, String[] jobsD)     {        return generalConcatAll (jobsA, jobsB, jobsC, jobsD);    }    public String[] generalConcatAll(String[]... jobs) {        int len = 0;        for (final String[] job : jobs) { len += job.length;        }        final String[] result = new String[len];        int currentPos = 0;        for (final String[] job : jobs) { System.arraycopy(job, 0, result, currentPos, job.length); currentPos += job.length;        }        return result;    }
