Write a Java program to reverse an array of integer values.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.Arrays;
public class Exercise11 {
public static void main(String[] args){
int[] my_array1 = {
1789, 2035, 1899, 1456, 2013,
1458, 2458, 1254, 1472, 2365,
1456, 2165, 1457, 2456};
System.out.println("Original array : "+Arrays.toString(my_array1));
for(int i = 0; i < my_array1.length / 2; i++)
{
int temp = my_array1[i];
my_array1[i] = my_array1[my_array1.length - i - 1];
my_array1[my_array1.length - i - 1] = temp;
}
System.out.println("Reverse array : "+Arrays.toString(my_array1));
}
}
Sample Output:
Original array : [1789, 2035, 1899, 1456, 2013, 1458, 2458, 1254, 1472, 2365, 1456, 2165, 1457, 2456] Reverse array : [2456, 1457, 2165, 1456, 2365, 1472, 1254, 2458, 1458, 2013, 1456, 1899, 2035, 1789]
