当我启动程序时:
Exception in thread "main" java.lang.NoSuchMethodError: Racuni.Tax.<init>(DLjava/lang/String;I)V
at Racuni.dd.main(dd.java:7).
请帮忙。
public class dd {
public static void main (String[] args) {
Tax t = new Tax(65000,"NJ",3);
System.out.println(t.dependents + t.grossIncome + t.state);
}
}
class Tax extends dd{
double grossIncome;
String state;
int dependents;
Tax(double gi, String st, int depen){
grossIncome= gi;
state = st;
dependents = depen;
}
}
答案 0 :(得分:0)
按照惯例,Java类型名称通常以大写字母开头。请将您的dd类更改为DD,因此将fileName dd.java更改为DD.java。并重新编译它应该工作正常。
