实时查看linux下tomcat运行日志

学不会看不懂:

[code=java]

public static void main(String[] args) {

List list = new ArrayList<>();

list.add("1");

list.add("2");

list.add("3");

int i = 0;

System.out.println(list.toString());

Iterator iterator = list.iterator();

while (iterator.hasNext()){

if(iterator.next()=="2"){

iterator.remove();

}

i++;

}

System.out.println(list.toString());

}
