Method for searching a numeric array:
//Method "search_Array" for searching the element
public static int Search_Array(int[] arr, int value)throws Exception
{
//Declare the variable "i" for controlling the loop
int i;
//Variable to hold the value
int var;
//Variable for indicating the search result
boolean found;
//Starting point of the search
i = 0;
//Storing the default values
var = -1;
//Assign "found" to "false"
found = false;
//While lopp to check the condition
while (!found && i<arr.length)
{
//Check the "val" resides in the specified index
if (arr[i] == value)
{
//Assign "found" to be "true"
found = true;
//Assign the "i" to "var"
var = i;
}
//Increment the loop variable
i++;
}
//Check the "var" equals to "-1"
if (var == -1)
//Print the error statement
throw new Exception("Element not found");
else
//Return the value of "var"
return var;
}
Explanation:
The above method “search_Array” is used to search the particular element in the array...

- Write an application that displays a series of at least eight student ID numbers (that you have stored in an array) and asks the user to enter a test letter grade for the student. Create an Exception class named GradeException that contains a static public array of valid grade letters (A, B, C, D, F, and I) that you can use to determine whether a grade entered from the application is valid. In your application, throw a GradeException if the user does not enter a valid letter grade. Catch the GradeException, and then display the message Invalid grade. In addition, store an I (for Incomplete) for any student for whom an exception is caught. At the end of the application, display all the student IDs and grades.arrow_forward1-Write a JAVA program that reads an array from input file and invokes twodifferent methods Sort and Max ,that sorts the elements of the array and findsthe Max element and writes out the resulted array in to output file .

If the value is not found, the function should throw an exception. int searchArray(int array[], int size, int value){ int index = 0; // Used as an index to search array int subscript = -1; // To record position of search value while (index < size && subscript == -1) { if (array[index] == value) // If the value is found ___________________________________________________ ___________________________________________________ } if (subscript == -1) ___________________________________________________ return subscript; } Bonus…arrow_forward
