Am doing my kitchen over and I will like to install a dish wascher. Is do I have to install 2 different lines for cold water and hot am moving the sink from where it is to put in a different location so I know I have to exten the pipe. Thanks

Most dish washers only have a hot water inlet. The dishwasher supply may be tee'd off from the sinks hot water supply,(and cold if needed. Regards, Tom

Keep in mind that you also need to install a drain from the dishwasher so keep the install next to the sink. If you have a garbage disposer you can connect the drain to the disposer. Remember to poke out the plug inside the disposer inlet.
