Program to reverse an Array
import java.util.Scanner;
public class Example
{
public static void main(String args[])
{
int counter, i=0, j=0, temp;
int number[] = new int[100];
Scanner scanner = new Scanner(System.in);
System.out.print("How many elements you want to enter: ");
counter = scanner.nextInt();
for(i=0; i<counter; i++)
{
System.out.print("Enter Array Element"+(i+1)+": ");
number[i] = scanner.nextInt();
}
j = i - 1;
i = 0;
scanner.close();
while(i<j)
{
temp = number[i];
number[i] = number[j];
number[j] = temp;
i++;
j--;
}
System.out.print("Reversed array: ");
for(i=0; i<counter; i++)
{
System.out.print(number[i]+ " ");
}
}
}
Output
How many elements you want to enter: 5
Enter Array Element1: 11
Enter Array Element2: 22
Enter Array Element3: 33
Enter Array Element4: 44
Enter Array Element5: 55
Reversed array: 55 44 33 22 11
