Week 2: Methods, strings and lists/3A. Parameters

public static void printLarger(int num1, int num2) {
    if (num1 > num2) {
        System.out.println(num1);
    } else {
        System.out.println(num2);
    }
}


public static void main(String[] args) {
    printLarger(10,4);
    printLarger(111, 11111);
    printLarger(5 * 5, 3 * 9);
}

Program outputs:
10
11111
27


====================

parameter data type
eg double



public class Example{
    public static void main(String[] args) {
        double a;
        a = 4.0;
        a = 24;
        float f = 23.32f;
        a = f;
    }
}






========================================



public class Example {
    public static void main(String[] args) {
        printSquare(3.5); //accept double
        printSquare(10);  //accept int
        printSquare(1.5f);//accept float
    }

    public static void printSquare(double num) {
        System.out.println(num * num);
    }
}

Program outputs:
12.25
100.0
2.25






========================================


Method parameters can also be of different types, for example:

public class Example {
    public static void main(String[] args) {
        tempBetween(10, 30, 25.5);
        tempBetween(-5, 5, -15.25);
    }

    public static void tempBetween(int min, int max, double temp) {
        if (temp >= min && temp <= max) {
            System.out.println("Temperature is between the given values!");
        } else {
            System.out.println("Temperature is not between the given values.");
        }
    }
}
Program outputs:

Temperature is between the given values!
Temperature is not between the given values.
