2. 后台技术：JavaBean
‌FinalLevelBean.java‌
public class FinalLevelBean {
private int dailyLiving;
private int mentalStatus;
private int sensoryCommunication;
private int socialInvolvement;
private int finalLevel;

// Getters and Setters
public int getDailyLiving() {
    return dailyLiving;
}

public void setDailyLiving(int dailyLiving) {
    this.dailyLiving = dailyLiving;
}

public int getMentalStatus() {
    return mentalStatus;
}

public void setMentalStatus(int mentalStatus) {
    this.mentalStatus = mentalStatus;
}

public int getSensoryCommunication() {
    return sensoryCommunication;
}

public void setSensoryCommunication(int sensoryCommunication) {
    this.sensoryCommunication = sensoryCommunication;
}

public int getSocialInvolvement() {
    return socialInvolvement;
}

public void setSocialInvolvement(int socialInvolvement) {
    this.socialInvolvement = socialInvolvement;
}

public int getFinalLevel() {
    return finalLevel;
}

public void setFinalLevel(int finalLevel) {
