I am making a maze game in Java. I have made a maze board, A start point and a end point. When i reach the end point then it exit and show a winning message. But i can not add a time limitation. Suppose player have to reach the end point with 30 seconds otherwise he lose the game.

System.currentTimeMillis(); // returns current time in milliseconds...

//save time at beggining of game, compare saved time to current time... when x time has passed... do something...

You have to basically create a separate thread which will take care of the time counter. To see how to create a thread you can refer

http://docs.oracle.com/javase/tutorial/essential/concurrency/runthread.html

After this you need to run the game on a separate thread and counter on another thread..To make a time counter you can take help from this previous post.

How can I count the time it takes a function to complete in Java?

Get current system time when you start a game:
long startTime = System.currentTimeMillis();

Than every time your tick/update method occours check how much time elapsed:
long elapsedTime = System.currentTimeMillis() - startTime;

elapsedTime holds elapsed time in miliseconds to get elapsed time in seconds just divide it with 1000:
elapsedTime\= 1000;

Now you can check how much time passed since the game was started,
For example: if(elapsedTime >= 30) running = false;

Have in mind that this is simplest implementation just to give you some idea of how it can be done in Java
