您当前的位置: public class Employee{
private int id;
private String name;
private String department;
private double salary;
public String getDepartment(){
return department;
}
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(){
this.name=name;
}
public double getSalary(){
return salary;
}
public void setSalary(double salary){
this.salary=salary;
}
}
------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);
}
}
