Answer with Explanation

Data types are important because they ensure that only valid operations are performed on data. Java follows strong type checking, which means:

  • Every variable must have a defined type
  • Only allowed operations are performed on that type
  • Invalid operations are not permitted

šŸ‘‰ This helps in:

  • Preventing errors
  • Improving program reliability
