关于list接口和set接口的示例应用

package ch;

public class Employee implements Comparable<Object> {
//生成名字和薪水两个对象。
    private double salsry;
    private String name;
//对其进行初始化
    public Employee(String name, double salsry) {
        super();
        this.name = name;
        this.salsry = salsry;
    }
//生成get和set方法
    public double getSalsry() {
        return salsry;
    }

    public void setSalsry(double salsry) {
        this.salsry = salsry;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
//进行重写和比较
    @Override
    public int compareTo(Object p) {
        // TODO Auto-generated method stub
        Employee p1=(Employee)p;
        if(this.salsry>p1.salsry)
            return 1;
        else if(this.salsry<p1.salsry)
            return -1;
        else
            return 0;
    }
    
}
