使用parseint将String转换为int(convert String to int with with parseint) java

我尝试将int String转换为int

int port = Integer.parseInt(tokens[2]);

tokens[2]包含一个String "12777"但是我收到了这个错误

Exception in thread "Thread-2019" java.lang.NumberFormatException: For input string: "12777" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Integer.parseInt(Integer.java:458) at java.lang.Integer.parseInt(Integer.java:499) at inet.ChildServer.hopen(ChildServer.java:88) at inet.ChildServer.run(ChildServer.java:51)

编辑：对不起，eclipse中的字符是不可见的，我不明白这是什么。我有一个这种形式的字符串

command1|Destination-IP|DestinationPort

而我只是把它弄乱了

String[] tokens = sentence.split( "[|]" );

I try to convert int String to int

int port = Integer.parseInt(tokens[2]);

tokens[2] contain a String "12777" But I got this error

Edit: Sorry the characters are invisible in eclipse, I don't Understand what is this. I have a String in this form

command1|Destination-IP|DestinationPort

and I just splot it

String[] tokens = sentence.split( "[|]" );
