如何在Array-list上添加对象的内容?
感谢,
这是我的代码
ArrayList soft1=new ArrayList();
if ("Software".equals((String)major.getSelectedItem())){
add(p2s,BorderLayout.CENTER);
p2s.setVisible(true);
p2n.setVisible(false);
p2sc.setVisible(false);
if (e.getSource()==save){
String id1=id.getText();
String name1=name.getText();
String gender11=(String)gender1.getSelectedItem();
String major1=(String)major.getSelectedItem();
StudentSoftware software=new StudentSoftware( studentID, studentName, gender, studentMajor, course1, course2, course3, mark1, mark2, mark3);
答案 0 :(得分:1)
您需要将POJO类的Arraylist声明为ArrayList<StudentSoftware> soft = new ArrayList<StudentSoftWare>()
。然后将StudentSoftware初始化为StudentSoftware student = new StudentSoftware()
,将设置值设置为POJOClass为student .setid(id)
,然后在POJOclass中生成setter和getter。最后将POJOclass对象添加到Arraylist中soft.add(student)
。
我觉得它对你有用......
