Class
In object-oriented programming (OOP), a class is a template that defines the structure and behavior of objects. A class is a logical entity that encapsulates its attributes (data members) and methods (functions).
package in.ihelpyou;
public class Calc {
public int a, b;
public int addition() {
return a + b;
}
public int subtraction() {
return a - b;
}
public static void main(String[] args) {
Calc obj = new Calc();
obj.a = 10;
obj.b = 20;
int c = obj.addition();
System.out.println("Sum: " + c);
}
