Question

java编程题求助？

Answer 1

简单一点的，类名自己改一下，我看不清
异常类：
public class ChushuException extends Exception{

public ChushuException() {
super();
}

public ChushuException(String message) {

super("异常就是我自己抛出去的："+message);
}
}
除法：
class ChuFa{
public static double div(double a, double b) throws ChushuException{
if(b == 0){
throw new ChushuException("数值为0");
}
return a/b;
}
}

测试的main方法
public static void main(String[] args) throws Exception{

try{
System.out.println(ChuFa.div(1.2,0));
}catch (ChushuException e){
System.out.println("捕获除数数值为0异常:"+ e.getMessage());
}

}
