java reverse array method code example
Example 1: reverse array in java
int length = array.length;
for(int i=0;i<length/2;i++) {
int swap = array[i];
array[i] = array[length-i-1];
array[length-i-1] = swap;
}
or
Collections.reverse(Arrays.asList(array));
Example 2: java string reverse
String rev = new StringBuilder("Your String").reverse().toString();
Example 3: reverse array java
for(int i=intArray.length-1;i>=0;i--)
System.out.print(intArray[i] + " ");
Example 4: reverse string array java
public class ReverseArrayDemo
{
public static void main(String[] args)
{
int[] arrNumbers = new int[]{2, 4, 6, 8, 10};
System.out.println("Given array: ");
for(int a = 0; a < arrNumbers.length; a++)
{
System.out.print(arrNumbers[a] + " ");
}
System.out.println("Reverse array: ");
for(int a = arrNumbers.length - 1; a >= 0; a--)
{
System.out.print(arrNumbers[a] + " ");
}
}
}
