请大神看一下我这个JAVA里面哪里有问题啊，为什么 public static void main(String[] args) 报错

package Test;
class Yuan{
private int empno;
private String ename;
private String job;
private double sal;
private double comm;
public Yuan(){};
public Yuan(int eno,String ena,String j,double s,double c){
empno=eno;
ename=ena;
job=j;
sal=s;
comm=c;
}
public void setEmpno(int eno){
empno=eno;
}
public void setEname(String ena){
ename=ena;
}
public void setJob(String j){
job=j;
}
public void setSal(double s){
sal=s;
}
public void segComm(double c){
comm=c;
}
public int getEmpno(){
return empno;
}
public String getEname(){
return ename;
}
public String getJob(){
return job;
}
public double getSal(){
return sal;
}
public double getComm(){
return comm;
}
public String getInfo(){
return "雇员编号："+empno+"\n"+
"雇员姓名："+ename+"\n"+
"雇员职位："+job+"\n"+
"基本工资："+sal+"\n"+
"雇员奖金："+comm;
}
public class OneOne{
public static void main(String[] args) {
// TODO Auto-generated method stub
Yuan Y=new Yuan(777,"sun","ceo",800.00,100.00);
System.out.println(Y.getInfo());
}
}
}

//将class OneOne 放到Yuan外面就行了
