如果您在超类中创建getter和setter，则可以通过这些方法访问变量。另一种可能性是将可见性从私有更改为受保护
雇员
public class Employee {
private String name;
private int id;
private double salary;
public Employee(String name, int id, double salary) {
super();
this.name = name;
this.id = id;
this.salary = salary;
}
public double getSalary() {
return salary;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public void setSalary(double salary) {
this.salary = salary;
}
@Override
public String toString() {
return "Employee [name=" + name + ", id=" + id + ", salary=" + salary + "]";
}
}
经理
public class Manager extends Employee {
private double bonus;
public Manager(String name, int id, double salary, int bonus) {
super(name, id, salary);
this.bonus = bonus;
}
public double getSalary() {
double baseSalary = super.getSalary();
return (baseSalary + baseSalary * (bonus / 100));
}
@Override
public String toString() {
return "Manager [name=" + getName() + ", id=" + getId() + ", salary=" + getSalary() + ", bonus=" + bonus + "]";
}
}
第二个（使用保护）
雇员
public class Employee {
protected String name;
protected int id;
protected double salary;
public Employee(String name, int id, double salary) {
super();
this.name = name;
this.id = id;
this.salary = salary;
}
public double getSalary() {
return salary;
}
@Override
public String toString() {
return "Employee [name=" + name + ", id=" + id + ", salary=" + salary + "]";
}
}
经理
public class Manager extends Employee {
protected double bonus;
public Manager(String name, int id, double salary, int bonus) {
super(name, id, salary);
this.bonus = bonus;
}
public double getSalary() {
double baseSalary = super.getSalary();
return (baseSalary + baseSalary * (bonus / 100));
}
@Override
public String toString() {
return "Manager [name=" + name + ", id=" + id + ", salary=" + salary + ", bonus=" + bonus + "]";
}
}
我个人会使用getter / setter方法，但这取决于您。
编辑：toString()在日食的日蚀的补充。您似乎无法使用getters和setter生成它（只是快速浏览，您可以在此处看到一些文档。我所做的工作是弄清楚如何编辑生成代码模板时使用的代码模板，toString()因此它包括toString()超类中的。
当您进入generate toString（）对话框时，<Default Template>旁边有一个字段“ String Format” 。当您单击编辑按钮时，您可以创建一个新的代码模板。该模板会自动保存<Default Template>和，看起来应该像这样：
${object.className} [${member.name()}=${member.value}, ${otherMembers}]
[super: ${object.superToString}]
这样，它将显示toString()超类的形式
