Question

In my current work, I have to write a replace function. A replace function, which take file path ( e.g., /sim/device ) as input and generates output – sim.device.

In java, I have tried with replace("/", "."). But, this function produce output .sim.device.

My question is that ” In Java, is there any function, which solves my purpose or should I write function myself ?” you could suggest efficient java code also.

Answer 1

If you want to ignore the first character you can use substring.

String text = "/my/sim/device";
String text2 = text.substring(1).replace('/','.');
System.out.println(text2);

prints

my.sim.device
