你可以这样做
右键单击任何包，如com.example.setu，然后单击New->package。这里只需要给予名称，如model。然后它会在该包下创建一个文件夹。您可以在此处添加POJO类，只需右键单击New-〉Java类

您可以通过简单的步骤创建模型类

• 创建java类名称 *

public class Wallet_Model {

    String date, amount, storeid, storename, description, type;

    public Wallet_Model(String date, String amount, String storeid, String storename, String description, String type) {
        this.date = date;
        this.amount = amount;
        this.storeid = storeid;
        this.storename = storename;
        this.description = description;
        this.type = type;
    }

    public Wallet_Model() {

    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getAmount() {
        return amount;
    }

    public void setAmount(String amount) {
        this.amount = amount;
    }

    public String getStoreid() {
        return storeid;
    }

    public void setStoreid(String storeid) {
        this.storeid = storeid;
    }

    public String getStorename() {
        return storename;
    }

    public void setStorename(String storename) {
        this.storename = storename;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }
}
