Taking multiple line input from user on java

Question

I am trying to get input from user with a for loop but for example if user enters "2" as a "noOfSubPattern" loop does not wait for the second input. I cannot find what is wrong in my code.

    int noOfSubPattern;
    String subPattern = "";
    noOfSubPattern = scan.nextInt();        


    for(int i = 0; i < noOfSubPattern; i++)
    {

        subPattern += scan.nextLine();
    }

You have to discard the line terminator after nextInt()

noOfSubPattern = scan.nextInt();
scan.nextLine(); // Discard line terminator

for(int i = 0; i < noOfSubPattern; i++) // ...
