Question

I would like to scan txt file and look for if statement (an if not a SOMETHINGifSOMETHING).

I was thinking about something like that

 [\\W|\\s]*if[\\s*|\\(]

but it does not work.

How can I make this "if" regex?

class Test {
  public static void main(String[] args) {
    // if (x > 10) a = b;
    int pif = 2;  // if
    int ifa = 3;
    int ifff;
    int kif;
    int cif;
    /*
     if
    */       
    
    int a = 0, b = 0, c;
    
    if (a > b) c = 1;  // wariant jest subwariantem
    if(a > b) c = 1;if (a<b) c=1; if(a==b) c= 7;
    if (a>b) c =1; else if (a==b) c=2;
    if (a>b) c =1; else {if(a==b) c=2;}
    if
    (a<b) c = 7;
  }
}

You can try this:

[;\s]+if[\s*|\(]

it will not know which are commented out, but it will find all the "if"s and not capture all the somethingIfSomethings.
