FileInputStream read multiple lines inside while loop due to if condition

Question

Actually this is my code :

inputStream = new FileInputStream(file);
sc = new Scanner(inputStream, "UTF-8");
while (sc.hasNextLine()) {
    String line = sc.nextLine();
    if(line.contains("blablbal") {
         // **take the next five line and put them inside string or something** 
    }
}

Is it possible to take the next five lines and put them inside string object?

And if there is another occurrence of the condition within these 5 lines how to treat that case?

Any idea?

Try with below code:-

          String[] lines = new String[20];
          //if you want to store more lines increase the size of the array
          int j = 0;
          //manage below while loop condition j < 20 based on array size and change the 
          //number from 20 to that number. For example if array size 50 make j < 50
          while (sc.hasNextLine() && j < 20) {
                    String line = sc.nextLine();
                if(line.contains("blablbal") {
                   int i = 0;
                   while(sc.hasNextLine() && i < 5){
                     line = sc.nextLine();
                     if(line.contains("blablbal") {
                        continue;
                     }
                     lines[j++] = line;
                     i++;
                     if ( j >= 20 )//change this according to the size of array as well
                        break;
                   }
                 }
