sqrt -1

sqrt(−1) = i

That may be context depend

Yes ..but I am confused ..can you give me an explanation...

A syntax error happens when a compiler or interpreter can't convert a program into machine code. The given code looks like valid Java syntax and should compile to JVM bytecode.

A runtime error happens when some error is triggered that's not dependent on your code. Things like out of memory, invalid memory access, race conditions etc.

Logic error happens when your code logic triggers a predicate error. In this case, your code logic is trying to take the sqrt of a negative number. That triggers an error. So it's a logic error.

24-25 is -1

Sqrt of -1, or even division by zero are not always errors. For example, floating point division by zero gives infinity instead of error. Similarly, some languages gives sqrt of -1 as i (complex number). It's really a mathematical concept where you can define what's acceptable and what is not.

A long time ago, negative numbers were considered impossible just like how sqrt -1 is today.

Btw why are they teaching java at maths tuition 🧐?
