More detailed code of the provided lesson:


public class Main {

// method = a block of code that is executed whenever it is called upon

// Since we are calling the add(int, int) function inside the main() method which is a STATIC method, therefore, we also need to make the add() method STATIC.
static int add(int x, int y) {

int z = x + y;
return z;
}
// In the above function definition, (int x, int y) are called parameters.

// Since we are calling the hello(String, int) function inside the main() method which is a STATIC method, therefore, we also need to make the hello(String, int) method STATIC.
static void hello(String name, int age) {
System.out.println("Hello "+name);
System.out.println("Your age is "+age);
}
// In the above function definition, (String name, int age) are called parameters.

// Driver Code:
public static void main(String[] args) {

int x = 3;
int y = 4;

// Calling method add(int, int)
int z = add(x, y);
// In add(x, y), x & y are called arguments.
// z = 7
System.out.println(z);

// Calling method hello(String, int)
hello("Pritam", 25);
// Hello Pritam
// Your age is 25.
// In hello("Pritam", 25), "Pritam" & 25 are called an arguments.
}
}

// Important Difference Between Argument and String.

// The values that are declared within a function when the function is called are known as an argument. Whereas, the variables that are defined when the function is declared are known as a parameter.
