Lab 2 (Solved)

Question 1

public class Addition
{
    public static void main( String args[] )
    {
        int number1 = 4;
        int number2 = 5;
        int sum;
        sum = number1 + number2;
        System.out.println( "Sum is " + sum );
    }
}

Question 2

public class Subtraction
{
    public static void main( String args[] )
    {
        int number1 = 5;
        int number2 = 7;
        int difference;
        difference = number1 - number2;
        System.out.println( "Difference is " + difference );
    }
}

Question 3

public class Addition
{

    public static void main( String args[] )
    {
        int number1 = 50;
        int number2 = 50;
        int number3 = 50;
        int sum;
        sum = number1 + number2 + number3;
        System.out.println( "Sum is " + sum );
    }
}

Question 4

public class AveThreeInts {
    public static void main(String[] args) {
        float num1 = 5;
        float num2 = 7;
        float num3 = 2;

        float average = (float)(num1 + num2 + num3) / 3;
        System.out.println("values of three integers are: 5 7 2 and the average is: " + average);

    }
}

Question 5

public class TwoFloats {
    public static void main(String[] args) {
        float num1 = 5.5f;
        float num2 = 7.8f;

        float sum = num1 + num2;
        float difference = num1 - num2;
        float product = num1 * num2;

        int intSum = (int) sum;
        int intDifference = (int) difference;
        int intProduct = (int) product;

        System.out.println("two floats are: " + num1 + " " + num2);
        System.out.println("Sum is: " + intSum);
        System.out.println("difference is: " + intDifference);
        System.out.println("product is: " + intProduct);
    }
}
