Q3_reverse_array

Program to reverse all elements of array in Java

In this program, we need to kwon how to work looping in descending /decreasing oder . This can be accomplished by looping through the array and store the elements of the array into the reverse oder array at the corresponding position.

Original array

1 2 3 4 5

Reverse array

5 4 3 2 1

Algorithm

• 1.START
• 2.INITIALIZE arr1[] ={1, 2, 3, 4, 5}
• 3.i=a.lenght;i>0,i--
• 4.display reverse oder array

Program

class Q3_reverse {

public static void main(String[] args)

//declare array

int arr[]={1,2,33,4,5};

System.out.println("original array is");

for(int i=0;i< arr.length;i++)

{

System.out.print(arr[i] + " ");

}

//display reverse array

System.out.println("reverse the array");

for(int i=arr.length;i>0;i--)

{

System.out.print(arr[i] + " ");

}

output

original array is:

1 2 33 4 5

reverse array is:

5 4 33 2 1
