What is the impact on memory usage when declaring a large two-dimensional array with most elements being zero?

  • Java allocates a separate memory block for each zero element, causing a substantial memory overhead.
  • Java automatically compresses the zero values, reducing memory usage.
  • No significant impact as Java optimizes storage for zero values using sparse array representations.
  • Significant increase in memory usage due to zero values being explicitly stored, wasting memory.
Java optimizes memory usage for large two-dimensional arrays with many zero elements by using a sparse array representation. It avoids storing explicit zero values, reducing memory consumption significantly. The other options do not reflect Java's memory optimization techniques for sparse data.
