The next method just pauses the program until the
Enter
key is pressed:
static void waitForEnter() {
try {
System.in.read();
} catch(IOException e) {
System.err.println(e);
}
}
MoveAndCopyFiles.java
Pausing the program is achieved by waiting for input from
System.in
. The
read()
can throw an excep-
tion of type
IOException
so the method call is in a
try
block.
The last method you need to complete the example is
main()
