------解决方案--------------------------------------------------------
java应用程序要运行必须要有public static void main(String[])类型的主函数入口，你这个程序没有，所以无法运行
给你贴个能跑的
- Java code
public class Employee{ private int id; private String name; private String department; private double salary; public String getDepartment(){ return department; } @Override public String toString() { return "Employee{" + "id=" + id + ", name='" + name + '\'' + ", department='" + department + '\'' + ", salary=" + salary + '}'; } public void setDepartment(String department){ this.department=department; } public int getId(){ return id; } public void setId(int id){ this.id=id; } public String getName(){ return name; } public void setName(String name){ this.name=name; } public double getSalary(){ return salary; } public void setSalary(double salary){ this.salary=salary; } public static void main(String[] args){ Employee e=new Employee(); e.setId(1); e.setName("demo1"); e.setSalary(1000.0); System.out.println(e); }}
