class Person{
String firstName = "" ;
String lastName = "" ;
Person () {
this.lastName = "Karl" ;
this.firstName = "Marx" ;
}
Person (String firstName , String lastName){
this.firstName = firstName ;
this.lastName = lastName ;
}
public String getName () {
return firstName + " " + lastName ;
}
public void setName (String firstName, String lastName ){
firstName = firstName ;
firstName = lastName ;
}
}
请问我要怎么才能让这个程序运行啊?
错误的提示是expection in thread "main"
java.lang.nosuchmathoderror: main
请问是什么意思啊``？
在下初学+自学 很多概念不是很懂 或许问题有点弱 望高手指点

//这里加上实例化的语句及对象的调用
}
另外：下面的要修改（但这个是与实例化的语句功能重复了）
public void setName (String firstName, String lastName ){
this.firstName = firstName;
this.firstName = lastName;
}
