Question

In Java

1.Given an unsorted array of doubles, write a program that Computes the sum of the array Finds the maximum in the array. (30 pts)

2.Given an array of ints sorted in ascending order, write a program to find the median in the array. (30 pts) (You may create your own array to test the program.)

3. Given a 6-by-8 two-dimensional array of ints and a target value, search the target value in the array. If found in the array, return its index, otherwise, return -1. (40 pts) (You may create your own array to test the program.)

Explanation / Answer

1.Given an unsorted array of doubles, write a program that Computes the sum of the array Finds the maximum in the array

//Please see the code below

public class ComputeSum
{
   static double sum;
   static double maxElement;
   public static void computeSumAndMaxElement(double[] array)
   {
       maxElement=0;

        for (int i=0; i < array.length; i++)
        {
           if(array[i]>maxElement)
               maxElement=array[i];
              
           sum += array[i];
        }
     
   }
public static void main(String[] args)
{
   double arr[]={1.1, 2.2, 5.5, 4.4, 2.4};
   computeSumAndMaxElement(arr);
   System.out.println("Sum is "+sum+" and Max element is "+maxElement);
}

}

2.Given an array of ints sorted in ascending order, write a program to find the median in the array.

public class ComputeMedian

{
  
public static void main(String[] args)
{
   int arr[]={1, 2, 3 ,4, 5};
   int middle = arr.length/2;
   int medianValue = 0;
   if (arr.length%2 == 1)
         medianValue = arr[middle];
   else
        medianValue = (arr[middle-1] + arr[middle]) / 2;
  
  
   System.out.println("Median of an array of Int is "+medianValue);
}

}

Given a 6-by-8 two-dimensional array of ints and a target value, search the target value in the array. If found in the array, return its index, otherwise, return -1

public class twoDimArray
{
  
   static int searchTargetValue (int [][] arr, int val)
   {
       for(int i=0;i<6;i++)
       {
             for(int j=0;j<8;j++)
             {
               if(arr[i][j]==val)
               {
                   System.out.println("The given element "+val+ " is present at index " +i+j);
                   return 0;
               }
              
             }
       }
      
       System.out.print("The given element "+val+ " is not present in array");
       return -1;
   }
  
public static void main(String[] args)
{
  
  
  
   int twoDimArr[][]= new int[6][8];
   int i,j;
   //Setting the value in 2-dimension array
   for(i=0;i<6;i++)
   {
         for(j=0;j<8;j++)
         {
           twoDimArr[i][j]=i+j;
          
         }
   }
  
   //Printing the value of 2-dimension array
   for(i=0;i<6;i++)
   {
         for( j=0;j<8;j++)
         {
           System.out.print(twoDimArr[i][j]+ " ");
          
         }
         System.out.println();
   }
  
  
   searchTargetValue(twoDimArr,10);
}

}
