判断device状态是否可以用

@Test

public void devices() throws Exception

{

Person p = new Person();

List<String> deviceslist = p.excmd("adb devices"); //执行adb devices命令 并且存放的list集合中

List<String> devlist = new ArrayList<String>();  //定义一个个list集合存放判断后的结果，有可能多个

    if (deviceslist.size() > 2) {

for (int i = 1;i < deviceslist.size() -1; i++) {  

String len[] = deviceslist.get(i).split("\t");  //split()分割函数

   if (len[1].trim().equals("device")) {

    devlist.add(len[0].trim());  //trim()去掉字符串首尾的空格  保存到list集合中去

}    

}

}

    else 

    {

System.out.println("没有匹配的设备");

}  

for(String s:devlist)  //通过foreach函数输出list集合内容

{

System.out.println("设备号：" +s);

}

}

@Test

public void tirmeFunt()

{

String s = " good good ";

String w = "good good";

System.out.println("判断s与w是否相等"+w.equals(s));

s = s.trim();

System.out.println("去掉左右空格在判断是否相等：=============");

System.out.println("判断s与w是否相等"+w.equals(s));

String b = "111,333,4444,555,2555,66666,4444433,44223,3666";

String[] a =  b.split(",");

String p = null;

for(String i:a)

{

System.out.println("输出结果是："+i);

}

System.out.println("合并结果"+p);

}
