请问怎么知道一行text的长度？

yechengyu

我想知道有没有一个直接的函数能够返回这一行有几个字符的？谢谢
FileReader fr_html=new FileReader(webpage);
    BufferedReader inFile2=new BufferedReader(fr_html);
   
    line2=inFile2.readLine();

"inFile2.readLine()" returns a object of String. So line2 is also a object of String.
You can get the length of line2 with "int lineLength = lines2.length();"

Hope, it's the answer that you want.
