Chapter 10, Problem 3AW

Explanation of Solution

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...
