What is the meaning and difference between carriage return and line feed in java?

\r Enter is to move the cursor to the front of a line.

\n Yes, move to the next line.

I'll analyze it for you sentence by sentence.

1 represents the cursor position.

system . out . print(" a ")；

Output:

a 1

system . out . print(" \ n ")；

Output:

a

1

system . out . print(" b ")；

a

b 1

system . out . print(" \ r ")；

a

1b

Note that the carriage return here moves the cursor in front of B, so B will be replaced when C is output next time.

system . out . print(" c ")；

a

c 1

The following is the same.

Analyze it yourself.
