Why does 1.0/0.0 not throw a java.lang.ArithmeticException: / by zero?

Question:

Why does 1.0/0.0 not throw a java.lang.ArithmeticException: / by zero?

Answer:

Floating point data types have a special value reserved to represent infinity, integer values do not.

The code 1/0 is an integer division fails. However, 1/0.0 is a floating point division and so results in Infinity.

Code:

public class Example {
 
  public static void main(String args[]){
    System.out.println("1.0 / 0.0 == " + 1.0/0.0);
  }
}

Output:

$ java Example
1.0 / 0.0 == Infinity
