        System.out.println(Math.min(9,8));
        //one positive and the other negative
        System.out.println("Minimum between -9 and 8:");
        System.out.println(Math.min(-9,8));
        // both negative numbers
        System.out.println("Minimum between -9 and -10:");
        System.out.println(Math.min(-9,-10));
        // both double numbers
        System.out.println("Minimum between 12.234 and 1.2345:");
        System.out.println(Math.min(12.234,1.2345));
        // one int and the other double 
        System.out.println("Minimum between 12.234 and 1:");
