SWT301_SE1955-JV

Defect ID: DF006

Defect Name: No validation for jagged (ragged) arrays

Line Number: 3

Defect Description: The implementation assumes all rows in A and B have the same length (non-jagged), but if rows have varying lengths the algorithm may access invalid indices or produce wrong results.

Fixing Solution: Validate that every A[i].length equals A[0].length and every B[i].length equals B[0].length before performing multiplication; throw IllegalArgumentException if not.
