Standard Streams in, out, and err

int size = System.in.read(teamName);

System.out.write(teamName,0,size);

System.out is the standard output stream that is used to output data from a program to the user:

System.out.print("Team complete");

System.err is the standard error stream that is used to output error data from a program to the user:
