Here, i’m gonna show you how to find the smallest number in an array java using Scanner class and without using Scanner class.

Let’s see find max value in array java,

#### JAVA PROGRAM TO FIND LARGEST AND SMALLEST NUMBER IN AN ARRAY WITHOUT USING SCANNER CLASS

```public class LargestSmallest
{
public static void main(String[] args)
{
// assigning array of 10 numbers to numerals
int numerals[] = new int[]{32,43,53,54,32,65,63,98,43,23};

// assigning first numeral of an array to largest and smallest

int largest = numerals[0];
int smallest = numerals[0];

for(int x = 1;x < numerals.length;x++)
{
if(numerals[x] > largest)
largest = numerals[x];
else if(numerals[x] < smallest)
smallest = numerals[x];
}
System.out.println("Largest Number is: " + largest);
System.out.println("Smallest Number is: " + smallest);
}
}

```

Output:

Largest Number is: 98
Smallest Number is: 23

```import java.util.Scanner;

public class LargestSmallest
{
public static void main(String[] args)
{
// assigning array of 10 numbers to numerals

int a;
Scanner sc = new Scanner(System.in);
System.out.println("Enter number of elements to find largest and smallest number: ");
a = sc.nextInt();
int numerals[] = new int[a];
System.out.println("Enter " + a + " integers.");

for(int b = 0;b < a;b++)
numerals[b] = sc.nextInt();

// assigning first numeral of an array to largest and smallest

int largest = numerals[0];
int smallest = numerals[0];

for(int x = 1;x < numerals.length;x++)
{
if(numerals[x] > largest)
largest = numerals[x];
else if(numerals[x] < smallest)
smallest = numerals[x];
}
System.out.println("Largest Number is: " + largest);
System.out.println("Smallest Number is: " + smallest);
}
}

```

Output:

Enter number of elements to find largest and smallest number: 10
Enter 10 integers. 23 34 90 34 31 67 89 12 40 87
Largest Number is: 90
Smallest Number is: 12

#### find max value in array java

Let’s learn how to find max element in array java with an example,

```import java.util.Scanner;

public class MaxValue
{
public static void main(String[] args)
{
int num, maxValue;
Scanner sc = new Scanner(System.in);
System.out.print("Please enter number of elements in the array : ");
num = sc.nextInt();
int arr[] = new int[num];
System.out.println("Please enter elements of array : ");
for(int a = 0; a < num; a++)
{
arr[a] = sc.nextInt();
}
maxValue = arr[0];
for(int a = 0; a < num; a++)
{
if(maxValue < arr[a])
{
maxValue = arr[a];
}
}
System.out.println("Max of array in java : " + maxValue);
sc.close();
}
}

```

Output:

Please enter number of elements in the array : 5
Please enter elements of array :
5
8
7
10
1
Max of array in java : 10
