帮我看一下为什么无法运行? 无法找到main class
class Person{
private String name;
private int age;

public String getName(){
return name;
}
public void setName(String name){
this.name=name;;
}
public int getAge(){
return age;
}
public void setAge(int age){
this.age=age;
}

}
class Address extends Person {

private String nation;
private String province;
private String city;
private String street;
private int postcode;

public String getNation(){
return nation;
}
public void setNation(String nation){
this.nation=nation;
}
public String getProvince(){
return province;
}
public void setProvince(String province){
this.province=province;
}
public String getCity(){
return city;
}
public void setCity(String city){
this.city=city;
}
public String getStreet(){
return street;
}
public void setStreet(String street){
this.street=street;
}
public int getPostcode(){
return postcode;
}
public void setPostcode(int postcode){
this.postcode=postcode;
}

}
public class test13 {
public static void main(String args[]){
Address adr=new Address();
adr.setName("TOM");
adr.setAge(21);
adr.setNation("China");
adr.setProvince("JiangSu");
adr.setCity("WuXi");
adr.setStreet("ZhangXiang");

adr.setPostcode(214183);

System.out.print("\tName\tAge\tNation\tProvince\tCity\tStreet\tPostcode");
System.out.println("");
System.out.print("\t"+adr.getName()+"\t"+adr.getAge()+"\t"+adr.getNation()+"\t"+adr.getProvince()+"\t"+adr.getCity()+"\t"+adr.getStreet()+"\t"+adr.getPostcode());
}

}
[解决办法]
试试 public static void main(String[] args) 这样写
