Question

java从TextArea读取字符

try {
bin = new BufferedReader(new FileReader(note.getText()));
while (bin.readLine() != null) {
count = count + 1;
}

上面的firereader要用什么替换才行啊

Answer 1

用：InputStreamReader替换即可!
另：
BufferedReader bin = new BufferedReader
(new InputStreamReader("此处写要读入文件的名称或者绝对路径"));
// bin 的类型要声明!
int count = 0; //count也要声明!
while(bin.readLine() != null) {
count = count + 1;
}

Answer 2

java.io.StringReader
