我很新，请帮助我。
我正在研究拇指扫描仪sdk。
当我正在调试代码时，它会卡在frame.setvisible(true)并且我的摇摆窗口没有出现。
我从我的主要方法
中调用它public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
JFrame_CSD200_FpCaptureAccess frame = new JFrame_CSD200_FpCaptureAccess();
frame.setVisible(true);
//frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
然后我的调试器转到
public JFrame_CSD200_FpCaptureAccess()
{
setResizable(false);
init();
}
这是init方法
public void init()
{
OutputStream out = new OutputStream() {
@Override
public void write(int b) throws IOException {
updateTextArea(String.valueOf((char) b));
}
@Override
public void write(byte[] b, int off, int len) throws IOException {
updateTextArea(new String(b, off, len));
}
@Override
public void write(byte[] b) throws IOException {
write(b, 0, b.length);
}
};
System.setOut(new PrintStream(out, true));
System.setErr(new PrintStream(out, true));

当我的光标到达frame.setvisible(true)时，它会卡在那里。我不知道我在哪里做错了。

尝试在init方法中仅使用setVisible(true)作为最后一个成员...并将其从EventQueue run()方法中删除
