short / Short / int / Integer / long / Long
When you perform divide by zero (0) on mentioned data types then it will give you java.lang.ArithmeticException: / by zero irrespective of Positive Number, Negative Number or even Zero(0).


float / Float / double / Double
When you perform divide by zero (0 or 0.0) on mentioned data type then it will give you different result based on Positive Number, Negative Number and Zero(0).

• Positive Number / 0 or Positive Number / 0.0 - Gives Infinity
• Negative Number / 0 or Negative Number / 0.0 - Gives -Infinity
• 0 / 0.0 or 0.0 / 0 - Gives Nan (Not A Number)
