JAVA类与测试类~求JAVA大神！！我快哭了~

实体类:

public class Employee0 {
private String name; // 名称
private Integer depNo; // 部门编号
private Double salary = 0.0; // 薪酬

public Employee0 (String name， Integer depNo， Double salary) {
this.name = name;
this.depNo = depNo;
this.salary = salary;
}

public void setDepNo(Integer depNo) {
this.depNo = depNo;
}

public Integer getDepNo() {
return depNo;
}

// 设工资
public void setSalary(Integer salary) {
this.salary = salary;
}

// 打印工资
public Double getSalary() {
return salary;
}

// 加薪
public void plusSalary(Double upper) {
this.salary += upper;
}
}

测试类:

import Employee0;

public class TestEmployee0 {
public static void main(String[] args) {
// 张三（部门编号：9527， 起薪: 4500)
Employee0 employee = new Employee0("Zhangsan"， 9527， 4500.0);
// 加薪前的薪水
Double plusBefore = employee.getSalary();
// 加薪100
employee.plusSalary(100.0);
// 加薪后的薪水
Double plusAfter = employee.getSalary();

// 输出
System.out.println("部门编号: " + employee.getDepNo);
System.out.println("加薪前薪酬: " + plusBefore);
System.out.println("加薪后薪酬: " + plusAfter);
}

}
