运行一个命令或程序获取结果/正则表达式查找匹配/分隔字符串

Process process1 = new ProcessBuilder("cat", "/opl/etc/system.prop").start(); BufferedReader br1 = new BufferedReader(new InputStreamReader(process1.getInputStream())); Pattern pattern = Pattern.compile("apps.setting.platformversion"); String line; while ((line = br1.readLine()) != null) { Matcher matcher = pattern.matcher(line); if(matcher.find(){ String[] temp = line.split(" = "); if(temp.length > 1) mRver.setSummary(temp[1]); else mRver.setSummary("/opl/etc/system.prop not configed well."); } } if(process1 != null) process1.destroy(); if(br1 != null) br1.close();
