问题描述
我的代码有问题
window.videoInfo.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
try {
URL url = new URL(window.videoInput.getText());
URLConnection con = url.openConnection();
LineNumberReader in = new LineNumberReader(new InputStreamReader(con.getInputStream()));
in.setLineNumber(1523);
in.getLineNumber();
System.out.print(in.readLine());
} catch (IOException ex) {
ex.printStackTrace();
}
我正在尝试显示来自网站的特定行.但是如果我按下按钮,它总是显示第一行.即使我将行号设置为 1523.
I am trying to display a specific Line from a website.But if i press the button it always displays the first line.Even when i set the line Number to 1523.
推荐答案
setLineNumber(1523)
只使 getLineNumber()
返回的行号以 开头1523
.它不会跳过 1523 行.要跳过 1523 行,您需要执行:
setLineNumber(1523)
only makes the line number returned by getLineNumber()
starts with 1523
. It won't skip 1523 lines. To skip 1523 lines, you need to do:
for(int i = 0; i < 1523; i++)
in.readLine();
