5.12 综合案例 ： 简单java类

• 简单java类，基础很重要，需要手，熟练无误的写出来

class Dept{
    private long deptno;
    private String dname;
    private String loc;

    public Dept(){// 必须提供无参构造方法;

    }

    public Dept(long deptno,String dname,String loc){
       this.deptno = deptno;
       this.dname = dname;
       this.loc = loc; 
    }

    public String getInfo(){
        return "[部门信息]部门编号:" + deptno + ",部门名称:" + dname + ",部门地址:" + loc;
    }

    public void setDeptno(long deptno){
        this.deptno = deptno;
    }

    public void setDname(String dname){
        this.dname = dname;
    }

    public void setLoc(String loc){
        this.loc = loc;
    }

    public long getDeptno(){
        return this.deptno;
    }

    public String getDname(){
        return this.dname;
    }

    public String getLoc(){
        return this.loc;
    }
}


public class HelloWorld {
    public static void main(String[] args) {
        Dept dept = new Dept(320302332,"技术部门","海天大厦");
        String info = dept.getInfo();
        System.out.println(info);
    }
}
