以下是一个简单的 Java 代码示例,展示了如何在除法运算前检查除数,以避免 java.lang.ArithmeticException: divide by zero 异常: java public class SafeDivision { public static void main(String[] args) { int dividend = 10; int divisor = 0; try
这行代码将被除数dividend除以除数divisor,并将结果存储在整数变量result中。由于除数为0,这行代码将引发“Division by zero”异常。 步骤4:处理可能引发的异常 try{intresult=dividend/divisor;// 执行除法运算System.out.println("结果: "+result);}catch(ArithmeticExceptione){System.out.println("除以零异常: "...
publicclassMain{publicstaticvoidmain(String[]args){int a=10;int b=0;try{int result=a/b;System.out.println("Result: "+result);}catch(ArithmeticException e){System.err.println("Error: Division by zero");}}} 通过捕获异常并提供有意义的错误消息,可以帮助用户或开发者快速定位和解决问题。
publicstaticvoidmain(String[]args){try{divideByZero(10,0);}catch(CustomExceptione){StringerrorMessage=e.getMessage();System.out.println("Error message: "+errorMessage);}} 1. 2. 3. 4. 5. 6. 7. 8. 运行该程序,输出结果将会是: Error message: Custom Exception: Division by zero 1. 流程...

System.out.println("Error: Division by zero is not allowed."); } 2.使用 try-catch 块捕获异常 try{intresult = dividend / divisor; }catch(ArithmeticException e) { System.out.println("Error: An arithmetic exception occurred - "+ e.getMessage()); ...

In the code above, we attempt to dividedividendbydivisor, which is zero. This will trigger a division by zero error, causing anArithmeticExceptionto be thrown. We catch this exception in a try-catch block and print an error message to the console. ...
