java112-simpledateformat进行格式化

package com.zx;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
//员工信息类
//date类
public class test50 {
private String name;
private String sex;
private Date birth;
public void showme(){
System.out.println(this.getName());
System.out.println(this.getSex());
// System.out.println(DateFormat.getDateInstance().format(this.getBirth()));
// System.out.println(this.getBirth());
//使用simpledateformat进行格式化
SimpleDateFormat sdf=new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
String data=sdf.format(birth);
System.out.println(data);
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getSex() {
return sex;
}
public void setBirth(Date birth) {
this.birth = birth;
}
public Date getBirth() {
return birth;
}
}
