Question

IN JAVA

write a class called mySchool that has no main method that provides the following (JUST HARD CODE NO MAIN)

min(int a, int b)

max(int a, int b)

avg(int a, int b)

sum(int a,int b)

convert(double a, string s) if s is F convert to celcius if s is C convert to faraenheit

Then write a seperate java program WITH a main to test all the methods from the class mySchool

Answer 1

class mySchool {

    public static int min(int a, int b) {
        if (a < b) {
            return a;
        } else {
            return b;
        }
    }

    public static int max(int a, int b) {
        if (a > b) {
            return a;
        } else {
            return b;
        }
    }

    public static double avg(int a, int b) {
        return (a + b) / 2.0;
    }

    public static int sum(int a, int b) {
        return a + b;
    }

    public static double convert(double a, String s) {
        if (s.equalsIgnoreCase("f")) {
            return (a - 32) / 1.8;
        } else {
            return a * 1.8 + 32;
        }
    }
}

class testMySchool {

    public static void main(String[] args) {
        System.out.println(mySchool.max(2, 1));
        System.out.println(mySchool.min(2, 1));
        System.out.println(mySchool.avg(3, 9));
        System.out.println(mySchool.sum(3, 9));

        System.out.println(mySchool.convert(100, "f"));
        System.out.println(mySchool.convert(38, "c"));
    }
}
