Java Multiplication Table - Fixed Enhanced Loop Visualization

✅ FIXED: The enhanced for-each loop now properly highlights ALL cells in purple, including the last row and column! Previously, the last cell (row 2, col 3 in a 3x4 table) wasn't being highlighted.

👨‍🎓 Student's Code (Enhanced For-Each Loop):


for (int[] row : table) {
    for (int value : row) {
        System.out.print(value + "\t");
    }
    System.out.println();
}

✨ This loop automatically iterates through each row and each value without using indices!

📝 Java Code - Phase 3: Printing with Enhanced For-Each (Student's Code)

// PHASE 1: Fill the multiplication table
int rows = 3;  // User input
int columns = 4;

int[][] table = new int[rows][columns];

for (int i = 0; i < rows; i++) {
    for (int j = 0; j < columns; j++) {
        table[i][j] = (i + 1) * (j + 1);
   }
}

// PHASE 2: Print using traditional loops
for (int i = 0; i < rows; i++) {
   for (int j = 0; j < columns; j++) {
       System.out.print(table[i][j] + "\t");
   }
   System.out.println();
}

// PHASE 3: Print using enhanced for-each loops
for (int[] row : table) {
   for (int value : row) {
       System.out.print(value + "\t");
   }
   System.out.println();
}

🔷 Traditional For Loops


                    for (int i = 0; i < rows; i++) {

                        for (int j = 0; j < columns; j++) {

                            // Access using indices

                            table[i][j] = ...

                        }

                    }

✅ Gives you access to indices (i, j)
✅ Can modify array elements

💜 Enhanced For-Each Loops (Student's Code)


                    for (int[] row : table) {

                        for (int value : row) {

                            // Direct access to values

                            System.out.print(value);

                        }

                    }

✅ Cleaner, more readable
✅ No indices to manage
❌ Cannot modify array elements
❌ No direct index access

📖 How Enhanced For-Each Works:
• for (int[] row : table) - Gets each entire row array one by one
• for (int value : row) - Gets each value in the current row one by one
• The loop automatically knows when to start the next row
• Purple cells show values that have been printed
• Blue cell shows the current value being printed
