Answer & Step-by-step explanation:
//written in java
// program uses a for loop to exchange the contents of the second column with the fifth column in a six rows and eight columns array
public class Main{
public static void main(String[] args) {
//specifying an integer to hold values during swap
int value = 0;
//sample array of
int[][] arr = {
{1, 2, 3, 4, 5, 6, 7, 8},
{1, 2, 3, 4, 5, 6, 7, 8},
{1, 2, 3, 4, 5, 6, 7, 8},
{1, 2, 3, 4, 5, 6, 7, 8},
{1, 2, 3, 4, 5, 6, 7, 8},
{1, 2, 3, 4, 5, 6, 7, 8},
};
//loop to swap column 2 and column 5
for (int i = 0; i < arr.length; i++) {
for (int j = 0; j < arr[i].length; j++) {
if(j==1){
value = arr[i][j];
}
if(j==4){
arr[i][1] = arr[i][j];
arr[i][j] = value;
}
}
}
//loop to print out result
for (int[] ints : arr) {
for (int anInt : ints) System.out.print(" " + anInt);
System.out.print("\n");
}
}
}
