求java正则:从一个select的SQL话语里获取表名_J2SE

求java正则:从一个select的SQL语句里获取表名
即从
select * from abc 获取abc
当然sql可能复杂多了。。比如
select a,b,c from a where id=1 order by id desc
SELECT * from a group by age

这样。求具体的java代码(对JAVA操作正则不太了解..@_@)

------解决方案--------------------
其实完全可以不用正则来解决，不过正则也快一点吧，下面是稍微粗糙的一个例子，我想应该能解决问题了

Java code

String sql="select a,b,c from abc where id=1 order by id desc";        String regex="\\bfrom\\s*\\S*";        Pattern p=Pattern.compile(regex);        Matcher m=p.matcher(sql);        if(m.find()){            String table=m.group().replace("from","");            System.out.println(""+table.trim());        }else{            System.out.println("not found");        }
------解决方案--------------------
            String str="select a,b,c from abc where id=1 order by id desc";
		Pattern p=Pattern.compile("(.*from\\s)(\\w*)(.*)");
		Matcher m=p.matcher(str);
		if(m.find()){
			System.out.println(m.group(2));
		}else{
			System.out.println("false");
		}
