Apr 9, 2025 · Given an array a [] of n elements, write a function to search for a given element x in a [] and return the index of the element where it is present. If the element is not present in the array, then return -1.

Aug 19, 2015 · Declaring an array variable, creating an array, and assigning the reference of the array to the variable can be combined in one statement, as shown below: String[] arrayRefVar = new String[arraySize]; This creates an array of size …

Jan 5, 2025 · Linear Search is a simple search algorithm that scans the array sequentially and compares each element with the key (target value). If the key is found, it returns the index; otherwise, it returns -1.

Feb 12, 2025 · If a match is found, the search terminates and returns the index of the element in the array that matches the key. If no match is found, the search returns -1 or some other value indicating a failure to locate key.

Write a Java program to perform a linear search on arrays using the for loop traverses array and if statement, and functions with examples.

Jan 11, 2025 · Step 1: Traverse over the array. Step 2: Match the key element with array element. Step 3: If key element is found, return the index position of the array element. Step 4: If key element is not found, return -1. Let's see an example of linear search in Java where we are going to search an element sequentially from an array.

Aug 22, 2022 · Linear Search in Java is the simplest and most basic searching algorithm. It is used to find the index of the desired element in an array. In this algorithm, we sequentially visit each element of an array until the target element is found.

Sep 6, 2021 · array[i] = input.nextInt(); } System.out.println("Enter the search value:"); int searchElement = input.nextInt(); for (int i = 0; i < length; i++) { if (array[i] == searchElement) { System.out.println(searchElement + " is present at index " + (i));

Here is the basic pseudocode for the linear search algorithm: if item == target value. return the index of the item. As you can see, the algorithm loops through each element in the array and compares it with the target value. If the target value is found, the index of the element is returned.

Nov 15, 2023 · Linear search is simple sequential search in which target element is searched one by one in the array. If element is found in the array then index will be returned else -1 will be returned.
