Compilation error but does not say anything else...

Question

https://code.sololearn.com/cPjdfw2R7wv7/?ref=app

This code above takes in a number and returns a Boolean value whether it is a prime number or not. Or at least it's supposed to. The problem is, I get an error.

Compilation error

...and nothing else.
What an I doing wrong and why doesn't the compiler spit specific errors?

Answer 1

tadashi akahori First of all, Java has nothing like Int.

int is a primitive data type contained in the Integer wrapper class.

the boolean variable ans should be a global (instance) variable as you're using it in two different methods.

for loop must have the following prototype:

for(initialization; condition; iteration)

* Check the semi-colons right there ;)

You forgot to give the findPrime method the boolean return type.

Answer 2

i assumed you copied the code from your ide to code playground?if so i would suggest to copy from the line of the main method leaving the class declaration just type it manually in the code playground

Answer 3

There are a lot of syntax errors and bugs. Here is the working code:

I hope you'd find them yourself 😏

Answer 4

Disorder🚸🔭🌎 no, I typed it straight into the editor, and Dev thanks a lot! I'll look at the bugs.

Answer 5

Dev thanks man! I didn't know that int arrays were done with "int", not the class name "Int". So, the variables cannot be accessed from the outside?

Answer 6

Dev thanks so much!!

Answer 7

One suggestion: I have noticed this also (compilation error without info) on SL... When it happen, try your code on others online code editors
