定义并测试一个代表员工的Employee类。员工属性包括“编号”、“姓名”、“基本薪水”、“薪水增长

privateintempno;//雇员编号
privateStringename;//雇员姓名
privatedoublesal;//基本工资
privatedoublerate;//工资增长额
publicEmployee(){
}
publicEmployee(intempno,Stringename,doublesal,doublerate){
super();
this.empno=empno;
this.ename=ename;
this.sal=sal;
this.rate=rate;
}
publicStringtoString(){
return"雇员编号："+this.empno+"，雇员姓名："+this.ename+"，基本工资："+this.sal;
}
publicvoidgrowthin(){//增长薪水
this.sal=this.sal*this.rate;
}
//setter、getter略
}
publicclassTestDemo{
publicstaticvoidmain(Stringargs[]){
Employeeemp=newEmployee(7369,"SMITH",1000,1.5);
emp.growthin();//工资增长
System.out.println(emp);
}
}
