{36187, 31876, 38761, 37861, 37618, 38671} 38761
class MaximumNumberInArray

{    public static void main(String s[])
    {
        int[] input = {2, 3, 8, 5, 4};
        int maximum = getMaximumNumberInArray(input);
        System.out.println("Maximum Number is " + maximum);

    }


public static int getMaximumNumberInArray(int[] array)
{
int result = 0;
//Write code here to get maximum number in array and assign it to result
return result;
}
}

        for(int outputElement : output)
        {
            System.out.print(outputElement + ", ");
        }

    }

//Write code here to reverse input array and assign it to output
return output;
}
}



Sum all elements in array

Write a program to get the sum of all elements in array.
Input (Integer Array) Output (Integer)
{2, 3, 4, 7, 6, 1} 2 + 3 + 4 + 7 + 6 + 1 = 23
{3, 9, 1, 5, 16, 10} 3 + 9 + 1 + 5 + 16 + 10 = 44
{21, 22, 23, 80, 443, 1521, 8000, 8080} 21 + 22 + 23 + 80 + 443 + 1521 + 8000 + 8090 = 18190
class SumOfNumbersInArray

{    public static void main(String s[])
    {
        int sum = getSumOfArrayElements(new int[]{2, 3, 4, 5, 8});
        System.out.println("Sum of elements in array is " + sum);

    }


public static int getSumOfArrayElements(int[] array)
{
int result = 0;
//Write code here to get sum of array elements and assign it to result

return result;
}
}



Multiply every array double element with 60

Write a program to multiply every array element with 6.0.
Input (Double Array) Output (Double Array)
{2.0, 3.1, 4.3, 7.5, 6.2, 1.0} {12.0, 18.6, 25.8, 45.0, 37.2, 6.0}
{3.0, 9.0, 1.0, -5.0, -16.0, 10.0} {18.0, 54.0, 6.0, -30.0, -96.0, 60.0}
class MultiplyEveryArrayElement

{    public static void main(String s[])
    {
        double[] input = {2.0, 3.1, 4.3, 7.5, 6.2, 1.0};
        double[] output = multiplyEveryElement(input);
        System.out.print("Result after multiplying by 6.0 is : ");
        for(double outputElement : output)
        {
            System.out.print(outputElement + ", ");
        }

    }


public static double[] multiplyEveryElement(double[] input)
{
double[] result = null;
//Write code here to multiplyEveryElement with 6.0 and assign it to result.
return result;
}
