My recommendation is to solve problems that you're interested in, writing code that might be useful to you.

Java is a huge box. It's got a lot of computer science inside: graphics, scientific computing, relational databases, user interfaces for desktop and web, messaging and queuing, multi-threading, security, and more. Each area has their own "beginner problem". Which one do you mean?

How do you define "beginner problem"? Maybe you're having trouble because you aren't narrowing your search enough. 

If your imagination is lacking, your best bet is to <a href="http://www.google.com/search?sourceid=chrome&amp;ie=UTF-8&amp;q=java+beginner+practice+problems" rel="nofollow noreferrer">Google something like "java beginner practice problems"</a> and investigate what you get back.

Or start with <a href="http://java.sun.com/docs/books/tutorial/" rel="nofollow noreferrer">Sun's on-line Java tutorial</a> and work you way all the way through it. You'll know a fair amount about Java when you're done.

blocks|key|1027919|text|如果你想学习一些图形用户界面，那么tic+tac+toe可能是不错的选择。即使对于控制台，我仍然发现这是一个有趣的问题。没有挑战性，但有一点乐趣。稍后，您可以升级一些其他游戏，或将游戏移植到GUI、客户端服务器或web上的java+applet。我认为如果你想学到一些东西并获得乐趣，游戏是一个很好的选择：)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1027920|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

If you wanted to learn some GUI, may be tic tac toe is good. Even for console, I still find that is a fun problem. Not challenging but a little bit fun. Later you can advance some other games or port that game to GUI, client server or java applet for the web. I think if you want to learn something and get fun as well, game is a good choice:)

blocks|key|1242818|text|一旦您精通Java+SE+(假设您能够通过SCJP)，我建议您获得初级Java程序员的工作，并提高自己在实际问题上的能力|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1242819|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Once you are quite good in Java SE (lets say you are able to pass SCJP), I'd suggest you get junior Java programmer job and improve yourself on real world problems

blocks|key|1242861|text|您可以在RosettaCode上尝试解决这些问题，其中许多目前都缺乏Java解决方案。这些问题有许多不同的困难，但每个问题都有另一种语言的解决方案，这应该有助于算法方面。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1242862|entityMap|0|LINK|mutability|MUTABLE|url|http://rosettacode.org/wiki/Main_Page^0|4|B|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You could try the problems at <a href="http://rosettacode.org/wiki/Main_Page" rel="nofollow noreferrer">RosettaCode</a>, many of which lack Java solutions at the moment. The problems are of many different difficulties, but each has a solution already in another language which should help with the algorithmic side.

blocks|key|1028048|text|去买一本名为"Java+examples+in+a+nutshell“的书。在这本书中，你会找到大多数实用的例子。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1028049|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Go and buy the book titled "Java examples in a nutshell". In the book you will find most of practical examples.

I have learned basics of Java but want to practice more. I was looking via Google and couldn't find many beginner level problems that I can solve using Java. 

Any suggestions?

我已经学到了Java的基础知识，但还想练习更多。我正在通过Google寻找，但找不到很多初学者级别的问题，我可以用Java解决。有什么建议吗？
