# Java program to find the largest and smallest number along with its index in an array of 10 element

##### What is an Array?

Array is a [collection](https://www.mindstick.com/articles/1718/collections-in-java) of similar type of [elements](https://www.mindstick.com/forum/1440/wpf-button-with-multiple-text-elements) that have contiguous memory location.

Java array is an object that contains elements of similar data type. It is a [data structure](https://www.mindstick.com/blog/11221/simple-way-to-learn-dynamic-data-structure-in-c-language) where we store similar elements. We can store only fixed set of elements in a java array.

Array in java is index based, first [element of the array](https://www.mindstick.com/forum/158053/how-to-remove-the-matching-element-of-the-array-in-javascript) is stored at 0 index.

\

##### Advantage of Java Array

[Code Optimization](https://www.mindstick.com/forum/157732/what-is-code-optimization-in-a-compiler-and-what-are-some-common-techniques-used-for-it): It makes the code optimized, we can retrieve or sort the data easily.

- [Random access](https://answers.mindstick.com/qa/102433/can-you-detail-the-functions-of-a-computer-s-random-access-memory-ram): We can get any data located at any index position.

##### Disadvantage of Java Array

Size Limit: We can store only fixed size of elements in the array. It doesn't grow its size at runtime. To [solve this problem](https://answers.mindstick.com/qa/94681/my-google-assistant-shows-completely-different-search-results-from-what-i-ask-how-can-i-solve-this-problem), collection [framework](https://www.mindstick.com/forum/34615/software-framework-vs-library) is used in java.

##### Thus we have the following program to accomplish our task:

##### *\*

##### *\*

```
package largestsmallest;import java.io.*;
public class LargestSmallest {
    public static void main(String[] args)throws IOException {        BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
        int num[]=new int[10];        int lindex=0,sindex=0;
        for(int i=0;i<10;i++)        {            System.out.println("enter a number");            num[i]=Integer.parseInt(br.readLine());         }        int smallest = num[0];        int largetst = num[0];        for(int i=1; i<10; i++)        {            if(num[i] > largetst)            {                largetst = num[i];                lindex=i;            }            if (num[i] < smallest)            {                 smallest = num[i];                 sindex=i;            }        }
    System.out.println("Largest Number is : " + largetst+" At Index "+ lindex);
    System.out.println("Smallest Number is : " + smallest+" At Index "+sindex);
}
```

##### OUTPUT:

enter a number 44 enter a number 8 enter a number 96 enter a number 2 enter a number 76 enter a number 49 enter a number 72 enter a number 184 enter a number 22 enter a number 12 Largest Number is : 184 At Index 7 Smallest Number is : 2 At Index 3
