Mutation Of A String

[alvin567]

//There will be 0.0 to 1.0% chance that the String will become "CHICKEN NUGGESTs"

public static String main(String arg){

Random rand = new Random();

int mutatePercentage = rand.nextInt(100);// if it's 0, means 0% chance. if it's 99, it means 1% chance

if(mutatePercentage==0){

return arg; // no change since % is 0

}

else if (rand.nextInt(10000) < mutatePercentage){

return mutateString(arg);

}

 

}

 

Hi there,

I found this piece of code from else where.

 

Where can I get the mutateString(arg) function?

Probably the same place.

public static String mutateString(String mutate){
  int max = 122;//largest ascii
  int min = 0;//smallest ascii range
  StringBuilder str = new StringBuilder(mutate);
  Random r = new Random();
  for(int i = 0; i < mutate.length();i++){
     if(0.50 >= r.nextDouble()){
        str.setCharAt(i, (char) r.nextInt(max - min + 1));
     }
  }
return str.toString();
}
