Infinity or exception in Java when divide by 0?
Consider the following code snippet where we divide a number by 0.
Example
public class Tester{
public static void main(String[] args) {
double d = 100;
System.out.println(d/0);
}
}Output
Infinity
Now consider the following code snippet.
Example
public class Tester{
public static void main(String[] args) {
int d = 100;
System.out.println(d/0);
}
}Output
Exception in thread "main" java.lang.ArithmeticException: / by zero at Tester.main(Tester.java:5)
As you've noted, the Infinity vs ArithmeticException, a different result for similar divide by zero program. The difference lies in floating point arithmetic used in first program and integer arithmetic used in second program.
