问题 This question has been asked before but I still cannot figure whats wrong for some reason. I got a class named NewClass in package syntaxtest in file src. From src path I type : javac src/syntaxtest/NewClass.java and the class is compiled and I can see NewClass.class in syntaxtest folder.

问题 Is there exist the opposite to the newline '\n' character in Java which will move back to the previous line in the console? 回答1: ASCII doesn't standardize a "line starve" or reverse line feed control character. Some character based terminals/terminal emulators recognize control code sequences that move the cursor up a line; these aren't Java-specific, and depend on your OS and configuration.

问题 I had a .profile file that I was reading and using aliases from in my terminal, but at some point the aliases stopped working for no clear reason (other commands were still working). Thinking to make a quick fix, I deleted (rm) and recreated my .profile file in my user directory. There are no bash_profiles or others in existence that I can see, at leasts in that directory. The new .profile did not work. I tried restarting the terminal and the computer. Now, the commands that worked in the

Other questions which are somewhat similar, but actually differ from my question relate to: Color-coding within the python script Importing color libraries within the script Using tools like Solarized to improve tools like Vim to color-code python code.
