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(Arithme
java.lang.ArithmeticException: division by zero是Java运行时抛出的一个异常,表明在进行数学运算时尝试将一个数除以零。在Java中,除数为零是不合法的操作,因此会触发此异常。 2. 指出在Java中哪些操作可能导致这个异常 在Java中,任何直接或间接尝试将数值除以零的操作都会导致ArithmeticException。这包括但不限于以下...
}catch(ArithmeticExceptione){//catchdivide-by-zeroerror System.out.println("Divisionbyzero."); } System.out.println("Aftercatchstatement."); } } 该程序输出如下: Divisionbyzero. Aftercatchstatement. 注意在try块中的对println()的调用是永远不会执行的。一旦异常被引发,程序控制由try块转到catch块。...

非检查型异常就是所谓的运行时异常(runtime exception),类似 NullPointerException、ArrayIndexOutOfBoundsException 之类,通常是可以编码避免的逻辑错误,具体根据需要来判断是否需要捕获,并不会在编译期强制要求。RuntimeException是非常特殊的子类,可以不用throw和throws。哪怕你throw了,也没必要throws; 即使你throws了,调...
public void division (int x, int y) throws BadNumberException { if (y==0){ throw new BadNumberException (“ Division by zero is not possible”); } Return x/y; } When the program control reaches the throw clause the lines of code after the throw block is not executed. The program ...
}catch(ArithmeticExceptione){ System.out.println("Divisionbyzero."); a=0;//setatozeroandcontinue } System.out.println("a:"+a); } } } 显示一个异常的描述 Throwable重载toString()方法(由Object定义),所以它返回一个包含异常描述的字符串。你可以通过在println()中传给异常一个参数来显示该异常的描述...
A negative or zero value is interpreted as no limit. If the limit is exceeded, the request will fail with a protocol exception. The JDK built-in implementation of the com.sun.net.httpserver.HttpServer implements a similar limit for the maximum request header size the server is prepared to ...
Internal exceptions are caused by illegal operations, such as division by zero, or Oracle errors returned to the PL/SQL code. User-defined exceptions are explicitly defined and signaled within the PL/SQL block to control processing of errors specific to the application (for example, debiting an...
