本文通过一个具体的Java代码示例，详细解析了超类与子类之间的继承关系，并指出了构造函数及方法调用中常见的错误。特别强调了赋值操作的正确使用方式。

代码块

//this is superclass
public class Employee {

    private String name;
    private double salary;

    public Employee(String name,double salary){
        this.name = name;
        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public double getSalary() {
        return salary;
    }
}

//this is subclass
public class Manager extends Employee{

    private double bonus;

    public void setBonus(double d){
        this.bonus = d; 
    }

    public Manager(String name,double salary) {
        //super(name,salary);
        super.getSalary() = salary;//The left-hand side of an assignment must be a variable
        bonus = 0;  
    }

    public double getSal(){
        double baseSalary = getSalary();
        return baseSalary + bonus;
    }
}
