我有两个数组要打印到单独的文件.这是我的代码:
try {
PrintStream out = new PrintStream(new FileOutputStream(
"Edges.txt"));
for (i = 0; i < bcount; i++) {
out.println(b[i][0] + " " + b[i][1]);
}
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
} catch (Exception ex) {
ex.printStackTrace();
}
try {
PrintStream out = new PrintStream(new FileOutputStream(
"Nodes.txt"));
for (i = 0; i < bigbIter; i++) {
out.println(bigb[i]);
}
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
} catch (Exception ex) {
ex.printStackTrace();
}

如果我只使用第一组try/catch/catch,它就能完美运行.但是当我使用它们时它不起作用,给我错误"非法启动类型...}捕获"和"错误:类,接口或枚举预期".我究竟做错了什么?
} catch (FileNotFoundException e) {
e.printStackTrace();
}
} catch (Exception ex) {
ex.printStackTrace();
}

你有一个额外的},它会抛出解析器,并给你很多错误.
