Class
A class is a prototype witch is create objects in opps programming. A class is combination of related fields and methods. This fields are public, private, protected, and final. And methods are static or non-static and final. There are many type of classes
Concrete class
A concrete class is basically public class because it’s easily access by another class.
Syntax.
Class class-name{
Access specifier datatype variable-name 1
Access specifier datatype variable-name 2
Access specifier datatype variable-name n
Access specifier datatype method-name(){
}
}
Final class
A final class is not extended class in oops programming. Because final is a non-access key word so can’t be extend the final class
Syntax.
final class class-name{
Access specifier datatype variable-name 1
Access specifier datatype variable-name 2
Access specifier datatype variable-name n
Access specifier datatype method-name(){
}
}
Example of class
Class ClassDemo{
private float PI=3.14159;
public void setPIValue(float fl)
{
PI=fl;
}
public float getPIValue()
{
return this.PI;
}
}
