Can't assign number inside for loop in Java

Question

Java

There was a task in Java, in which I am not particularly strong. It is necessary to assign a variable that is outside the block. How to do it? Tried as below, but nothing gets logged:

int index=0;                                   
      for( int j=0; j<passwords.length;j++)
      {
                if(passwords[j].equals(ov.getValue().toString()))
                 {
                      index = j;//Тут надо присвоить переменной, которая находиться вне блока. Как?
                      break;
                  }
      }

Answer 1

The code looks correct. Are you sure that the condition is met?
And in general to you algorithmic decomposition to apply. Something like:

int findPasswordIndex(String passwords[], String password)
{
      for( int j=0; j<passwords.length;j++)
      {
                if(passwords[j].equals(password))
                 {
                      return j;
                  }
      }
      // кинуть исключение - индекс не найден, или вернуть специальное значение
}

... 
int index = findPasswordIndex(passwords, ov.getValue().toString());
