Hello,
I have this part of source code
for(int i=0;i<num;i++) { System.out.println("Recored number: " + i+1 + " is:"); .... }
Why the result of the println is "01" and not just "1" ?

Printing i+1

Java treats that as a String concatenation. You need nested braces:
System.out.println("Recored number: " + (i+1) + " is:");
