title: How do I fix my java program not stopping running?
body: <p>I am writing a simple program as some practice for Java. It takes in integers and puts them into a two-dimensional array of R rows and C columns and then simply prints out each element of the array (just for troubleshooting). When I run the code it prints every integer like it should but the program does not stop running. I have to force stop it. Why is it not stopping on its own? I tried some basic debugging and tried to see if I accidentally had an infinite loop in the code but I couldn't find it. </p>
  
  <p>In case it is important I am using IntelliJ Idea Ultimate 2019.3.</p>
  
  <p>Thanks</p>
  
  <pre><code>import java.util.*;
  
  public class Main {
      public static void main(String[] args) {
          Scanner in = new Scanner(System.in);
          int T = in.nextInt(); //Takes number of test cases
          for(int i = 1; i &lt;= T; i++){ //This is the counter for each test case
              int R = in.nextInt(); //R is # of rows
              int C = in.nextInt(); //C is # of columns
              int K = in.nextInt(); //K is the thickness allowed
              int numArray[][] = new int[R+1][C+1];
  
              for(int j = 0; j &lt; R; j++){
                  for(int k = 0; k &lt; C; k++){
                      numArray[j][k] = in.nextInt();
                      System.out.println(numArray[j][k]);
                  }
              }
  
          }
          in.close();
      }//End of main
  }//End of main class

  (and here the cursor is stuck blinking not doing anything and the program doesn't quit on its own)</p>
  
  <p>I solved the issue by manually typing the input instead of copying and pasting it. Not sure what caused that issue but it worked!</p>
