Question

I got this warning on Sonar as a violation. I want proper solution to remove this warning from sonar.

My code is like this:

void method(){
try {
  int x;
  x=5;
 }
 catch{
    //handling code
 }
}

I got warning for this code like:

'5' is a magic number.

So, I want proper solution to remove such warning.

Answer 1

Magic number is the direct usage of the number in the code(i.e., hard-coded number in the code in your case using 5 directly)

to get rid of the warning try this:

 int x;
 static final int SOME_NUMBER=5;
 x=SOME_NUMBER;
