Task: Write a Java Array Program Implement Linear Search Algorithm. Input 10 numbers in array. Input a number to search in the array. Find index of this item in array of 10 integers.

The source code for Linear Search program using array in Java programming Language:

/* * Write a Java program to Search an item in array of 10 integers. Use Linear search algorithm */ package linearsearchjava; import java.util.Scanner; /** * @author www.EasyCodeBook.com */ public class LinearSearchJava { public static void main(String[] args) { int a[]=new int[10], i, item, itemIndex=-1; Scanner input = new Scanner(System.in); for(i=0;i<a.length;i++) { System.out.print("Enter Number in Array["+i+"]="); a[i] = input.nextInt(); } System.out.print("Enter Number to search in Array:"); item = input.nextInt(); for(i=0;i<a.length;i++) if(a[i]==item) { itemIndex=i; break; } if(itemIndex==-1) System.out.println("Number "+item+" not found in array!"); else System.out.println("Number "+item+" found on index="+i); } }

The sample run of the program and output is as shown below:

Enter Number in Array[0]=10

Enter Number in Array[1]=20

Enter Number in Array[2]=30

Enter Number in Array[3]=40

Enter Number in Array[4]=50

Enter Number in Array[5]=60

Enter Number in Array[6]=70

Enter Number in Array[7]=80

Enter Number in Array[8]=90

Enter Number in Array[9]=100

Enter Number to search in Array:70

Number 70 found on index=6
