Scanner scanner = new Scanner();
int number = 1;

do
{
    try
    {
        option = scanner.nextInt();
    }
    catch (InputMismatchException exception)
    {
        System.out.println("Integers only,please.");
    }
}
while (number != 0);

尽管存在异常处理,但在给出非整数输入时,此代码将进入无限循环.它不再是Scanner在下一次迭代中暂停收集输入,而是继续抛出InputMismatchExceptions直到程序被终止.

扫描整数(或其他类型,我猜)输入,丢弃无效输入并正常继续循环的最佳方法是什么？
