DOM edits for XML files in Java

2. Recommended a corresponding Member JavaBean:

/ * * Created on 2004-7-10 * * Todo to change the template for this generated file go to * window - preferences - java - code style - code templates * /

/ ** * @author Huang Jinxiang * * TODO To change the template for this generated type comment go to * Window - Preferences - Java - Code Style - Code Templates * / public class Member {private String username; private String password; private String Private string birth; private string email; private string pender; private string zipcode;

public String getAddress () {return address;} public void setAddress (String address) {this.address = address;} public String getBirth () {return birth;} public void setBirth (String birth) {this.birth = birth;} public String getContact () {return contact;} public void setContact (String contact) {this.contact = contact;} public String getEmail () {return email;} public void setEmail (String email) {this.email = email;} public String getGender () {return gender;} public void setGender (String gender) {this.gender = gender;} public String getPassword () {return password;} public void setPassword (String password) {this.password = password;} public String getRealname () {return realname;} public void setRealname (String realname) {this.realname = realname;} public String getUsername () {return username;} public void setUsername (String username) {this.username = username;} Public string getzipcode () {return zipcode;} public void setzipcode e) {this.zipcode = zipcode;}} Because the XML is in the String format, I use String to reply to String, and the user can pass the integer.parseint (). Helper to change its type. . 3. Eliance with DOM:
