Class instance Methods
In this chapter you will learn:
Define class instance methods
Methods are functions that manipulate the data defined by the class. Your program will interact with a class through its methods. The general form of a method is shown here:
access ret-type name(parameter-list) {
// body of method
}
- The
accessdetermines what other parts of a program can call the method. - The
ret-typespecifies the type of data returned by the method. - The
parameter-listis a sequence of type and identifier pairs separated by commas.
The following code creates a class called Calculator
first and then adds a method named All to it.
using System;// ja v a 2 s.c o m
class Calculator
{
public int Add(int x, int y)
{
return x + y;
}
}
public class MainClass
{
public static void Main(){
Calculator calc = new Calculator();
int sum = calc.Add(3, 5);
Console.WriteLine("3 + 5 = {0}", sum);
}
}
The code above generates the following result.
