Record.javapublic class Record {! String description;! int type;! int cost;!}

How about getter & setterAndroid Studio Tool

Record.javapublic class Record {! String description;! int type;! int cost;!!

public String getDescription() {! return description;! }!!

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

Repeat steps on other fields

But how about naming conventionpublic class Record {! String mDescription;! int mType;! int mCost;!}

Getter & Setter public class Record {! String mDescription;! int mType;! int mCost;!!

public String getmDescription() {! return mDescription;! }!!

public void setmDescription(String mDescription) {! this.mDescription = mDescription;! }!}

Not good

public String getDescription() {! return mDescription;! }!!

public void setDescription(String description) {! mDescription = description;! }!}
