## Solve InputMismatchException

I'm making a numbrosia puzzle for one of my classes. The problem that I'm having is trying to find some way to tell the user to follow instructions if an integer isn't entered. I can do it if the number is bigger than expected but not if its a letter or anything else. My guess is that it starts around where it says "int i = scan.nextInt();". I can also catch if the user doesn't input a correct move command. input.txt is just where I have the numbers for the puzzle. Also I didn't want to type all my methods like RU, RD, plusRow, etc. because I already wrote too much in my opinion ha Any help is appreciated. Thanks in advance.

```import java.io.*;
import java.util.Scanner;
public class Numbrosia {
static int [][] gameBoard = new int[5][5];
public static void main(String[] arg){
Scanner fileReader = null, scan = null;
//Scanner scan = new Scanner(System.in);

try{
scan = new Scanner(System.in);
}
catch (Exception e){
System.out.println(e);

}
for(int i = 0; i < 5; i++) //reading game board
for(int j = 0; j < 5; j++)

while(true){
showBoard();
System.out.println("");
System.out.println("Input number from 1 to 5: ");
int i = scan.nextInt();
System.out.println("Input move command: ");
String moveName = scan.next();
try{
if(moveName.equals("rl")){

RL(i-1);
}
else if(moveName.equals("rr")){

RR(i-1);
}
else if(moveName.equals("ru")){

RU(i-1);
}
else if(moveName.equals("rd")){

RD(i-1);
}
else if(moveName.equals("+r")){

plusRow(i-1);
}
else if(moveName.equals("-r")){

minusRow(i-1);
}
else if(moveName.equals("+c")){

plusColumn(i-1);
}
else if(moveName.equals("-c")){

minusColumn(i-1);
}
else{
System.out.println("");
