  1.   

    看看SQL的基本定义  应该就能做了
      

  2.   

    说错了,还以为是数据库呢,其实看了java课本上的例子,模仿着写就行。
      

  3.   


    public class Employee { private int id;
    private String name;
    private double salary;
    private double byPercent;

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

    public int getId(){
    return id;
    }

    public void setId(int id) {
    this.id = id;
    } public String getName() {
    return name;
    }

    public void setName(String name) {
    this.name = name;
    }
    public double getSalary() {
    return salary;
    }
    public void setSalary(double salary) {
    this.salary = salary;
    }
    public double getByPercent() {
    return byPercent;
    }
    public void setByPercent(double byPercent) {
    this.byPercent = byPercent;
    }

    public double raiseSalary(){

    return salary += salary * byPercent/100;
    } public static void main(String[] args) {
    Employee e1 = new Employee(00001,"张三",1500,20);
    Employee e2 = new Employee(00002,"李四",2000,30);

    System.out.println("编号"+"   "+"员工"+"   "+"基本工资"+"   "+"增长率%"+"   "+"总额");
    System.out.println(e1.getId()+"    "+e1.getName()+"     "
    +e1.getSalary()+"   "+e1.getByPercent()+"   "+ e1.raiseSalary());
    System.out.println(e2.getId()+"    "+e2.getName()+"     "
    +e2.getSalary()+"   "+e2.getByPercent()+"   "+ e2.raiseSalary());
    }}
