本程序的功能是给公司的员工Tom，Jack，Green增加薪水。三人的职位分别是programmer， Manager，CEO。
程序由6个类组成：WorkerTest是主类，programmer，Manager，CEO三个类，薪水增加的规则是 programmer的涨幅是5%；Manager的是10%；CEO也是Manager，但是它除了有Manager的涨幅，还有1000元的bonus。接口SalaryRaise提供了一个增加薪水的方法raise()。
[java程序]
public class WorkerTest {
public WorkerTest( ) {}
public static void main( String[] args) {
Programmer programmer = new Programmer( "Tom" ,3000);
Manager manager = new Manager( "Jack" ,4000);
CEO ceo = new CEO( "Green" ,4000);
Worker [] worker = new Worker[3];
programmer, raise( );
manager, raise( );
ceo. raise( );
worker[0] = programmer;
worker [1] = manager;
worker[2] = ceo;
for ( int i = 0 ;i ＜ worker, length; i + + ) {
System. out. prinfln (" Name:" + worker [i]. getName ( ) +" \ tSalary:" + worker [i]. getSalary ());
public interface SalaryRaise { void raise( ); }
public class Worker {
public String name;
public double (1);
public Worker( ) {}
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 class Programmer extends Worker implements (2) {
public Programmer( ) {}
public void raise( ) {
