Question

In the test class below, integrate another method to existing method to:

Print the minimum values of each row and of each column.

public class ArrayTest {

public static void main(String[] args) {
int[][] myArray = {{1, 4, 3, 2}, {2, 4, 8, 6}, {3, 3, 3, 3}};

int[] rowMax = ArrayOperations2D.findRowMax(myArray);
for (int i = 0; i < rowMax.length; i++) {
System.out.println("Max in row " + i + " = " + rowMax[i]);
}

int[] rowSums = ArrayOperations2D.findRowSums(myArray);
for (int i = 0; i < rowSums.length; i++) {
System.out.println("Sum in row " + i + " = " + rowSums[i]);
}

int[] columnMax = ArrayOperations2D.findColumnMax(myArray);
for (int i = 0; i < columnMax.length; i++) {
System.out.println("Max in column " + i + " = " + columnMax[i]);
}

int[] columnSums = ArrayOperations2D.findColumnSums(myArray);
for (int i = 0; i < columnSums.length; i++) {
System.out.println("Sum in column " + i + " = " + columnSums[i]);
}

int[][] transpose = ArrayOperations2D.findTranspose(myArray);
System.out.println("Transpose of the matrix:");
for (int i = 0; i < transpose.length; i++) {
for (int j = 0; j < transpose[0].length; j++) {
System.out.print(transpose[i][j] + " ");
}
System.out.println();
}
}
}
