java的application该怎么写
application是这个吗
package Entity;
public class User {
private String name;
private String number;
private String code;
private String character;
private String status;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getCharacter() {
return character;
}
public void setCharacter(String character) {
this.character = character;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
//ArrayList<User> UserList;
}
<%=n %>括起来的就是java代码，你要放到java文件里面，用法一样的，直接去掉%>
application不是我们写的，他是JSP的默认9大内置对象。这位【吕布辕门】老哥给你说的对着呢
