几个简单的java学习代码

   public class Employee {
  	private static final double BASE_ SALARY = 15000.00;
  	private String name;
  	private double salary;
  	private Date birthDate;
 
  	public Employee( String name, double salary, Date DoB) {
  		this. name = name;
  		this. salary = salary;
  		this. birthDate = DoB;	
	}			

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

 	public Employee( String name, Date DoB) {
 		this( name, BASE_ SALARY, DoB);
 	}

 	public Employee( String name) {
 		this( name, BASE_ SALARY);
 	}
