This is my memo
Can be output by inputting a literal in ()
Enclose in "" (double quotation marks) for strings
** Firmly attach a semicolon **
System.out.println () is an "instruction" to output (display) the contents of ().
print () does not end with a newline, but println () automatically inserts a newline at the end.
I could write more, but I stopped because my understanding was ambiguous. Next time I wish I could write the difference between the compiler and the interpreter in my own words ..
