for (int ab = 0; ab < 10; ab ++)
{
try
{

ans=input.nextInt();
ans = 1;
int c = coll.nextInt(4);
int qwe = roww.nextInt(4);
System.out.print("[" + board[c][qwe] + "]");

You shouldn't be using try/catch for this. Read the input as a string and then compare it to "1"

if ("1".equals(stringInput)){
 
}
