Android App Development ฉบับสมบูรณ์

ตัวอย่างการประกาศเมธอด เช่น
public void setWeight(double dblWeight)
{
weightCat = dblWeight;
}
public void setHeight(double dblHeight)
{
heightCat = dblHeight;
}
public double upWeight(double dblWeight)
{
weightCat = weightCat + dblWeight;
return weightCat;
}
public double downWeight(double dblWeight)
{
weightCat = weightCat - dblWeight;
return weightCat;
}
public double upHeight(double dblHeight)
{
heightCat = heightCat + dblHeight;
return heightCat;
}
จากตัวอย่างการสร้างคลาส การประกาศแอตทริบิวต์ และการประกาศเมธอด ซึ่งจะได้คลาสดังนี้
public class Cat {
private String nameCat;
private String colorCat;
public double heightCat;
public double weightCat;
public void setWeight(double dblWeight)
{
weightCat = dblWeight;
}
public void setHeight(double dblHeight)
{
heightCat = dblHeight;
}
public double upWeight(double dblWeight)
{
weightCat = weightCat + dblWeight;
return weightCat;
}
public double downWeight(double dblWeight)
{
