老是提示缺少一个“[”，但是怎么看看不出来毛病，大虾帮忙！~
D:\JavaWork\UpperCase\UpperCase.java:22: '] ' expected
Character newbuf[i] = new Character(buf[i]);
------解决方案--------------------
很多错误，类型，方法都不对。
改成下面，
public void toUpperCase(StringReader sr,StringWriter sw)
{
char [] buf = new char[1024];
char [] bufw = new char[1024];
int len = 0;
int j = 0;
try
{
len = sr.read(buf);
Character newbuf ;
for(int i = 0;i < len;i++)
{
newbuf = buf[i];
if(Character.isLetter(newbuf) && Character.isLowerCase(newbuf))
{
bufw[j] = newbuf.toUpperCase(newbuf.charValue());
j++;
}
}
sw.write(bufw);
}
catch (Exception e)
{
}
}
------解决方案--------------------
我试了就是好着呢啊，我用的eclipse3.2.2
------解决方案--------------------
都搞好咯..我来接分吧
