java try多个异常 java try catch 多个exception Java异常处理 try catch finally 多重catch 异常分类处理 输入两个数进行求商 使用if-else语句实现实现处理异常 import java.util.Scanner; public class Test { public static void main(String[] args) {...
Program continues after exception handling. 2. 多个异常的处理 问题描述 有时程序中可能会抛出多种类型的异常,需要分别处理每种异常。 示例代码 以下代码展示了如何通过多个catch块处理不同类型的异常: java import java.util.InputMismatchException; import java.util.Scanner;</p> ...
} catch (java.util.InputMismatchException e) { // if the user enters something that is not an integer System.out.println("Please only enter integers"); input = Integer.MIN_VALUE; stdin.next(); // consume the non-int so we don't get caught in an endless loop ...
while (true) { // loops forever until break try { // checks code for exceptions System.out.println("How many racers should" + " participate in the race?"); amountRacers = in.nextInt(); break; // if no exceptions breaks out of loop } catch (InputMismatchException e) { // if an...
