Char values of 13 and 10 in java

I’m doing some compiler stuff for json, and I ran into a bit of a problem.

There seems to be 2 values in my string that I don’t understand. At first, I thought that 13 and 10 were “\n” thingy, but it doesn’t seem so.

Values of 13 and 10 are both new line symbols… I mean, I’m kinda lost here… What do 13 and 10 represent? Should I just count both of them as new line symbols?
