Java 无限时循环

出于某种原因，我的循环永远不会结束，尽管用户特别指定了扫描器读取的值。当用户键入0时，它将继续

public static void InseretToDB() throws IOException {
    IO init = new IO();
    Scanner scan = init.getScanner();
    BufferedWriter bWriter = init.getWriter();
    int j;

    do {
        System.out.println("Name");
        String name = scan.nextLine();
        bWriter.write(name);
        bWriter.write("      ");
        System.out.println("Ocuppation");
        String occupation = scan.nextLine();
        bWriter.write(occupation);
        bWriter.newLine();
        System.out.println(" Input 1 to continue, 0 to end");
        j = (int) Integer.parseInt(scan.nextLine());
    } while (j != 0);

}

当我键入0时，循环确实结束了，但我将程序更改为以下内容

Scanner scan = new Scanner(System.in);
BufferedWriter bWriter = new BufferedWriter(new OutputStreamWriter(System.out));

希望这有帮助，

将扫描仪初始化为

 Scanner scan = new Scanner(System.in);

从中替换当前代码

j = (int) Integer.parseInt(scan.nextLine());

当j=0时，循环将结束…您在哪里调用InseretToDB方法？在主类的switch语句中使用scanner而不定义字符集，由于某种原因工作。那是一些严重的恶作剧！请注意：以后输入数字时不要更改字符集

try{
    j = scan.nextInt();
}catch(Exception e){
   j = -1;
}
