Debugging Exercise 10

Goal: debug the Transpose.java code.

From Java Bootcamp Resources -> Module 2 -> 8. Exception Handling -> Debugging Workbooks open the folder, exercise-10.

Debugging

The transpose of a matrix reverses the columns and rows. In other words, each row from the original matrix becomes a column in the new matrix.

Your code starts with the following matrix:

>>: [1, 2, 3]

>>: [4, 5, 6]

>>: [7, 8, 9]

The goal is to transpose it:

>>: [1, 4, 7]

>>: [2, 5, 8]

>>: [3, 6, 9]

But, your code produces:

>>: [1, 4, 7]

>>: [4, 5, 8]

>>: [7, 8, 9]

Use breakpoints to visualize the runtime. Watching the output line by line will help you debug the problem.

HINT: The solution may involve creating another 2D array.

Good Luck!
