Document Summary

Interactive development environments combine the first steps into one the bytecode is generated as the source is being typed. In a shell environment (like this csc120), the second step is accomplished by executing a line command javac (compiles: there are different text editors you can use like vim, sublime, gedit, emacs. Hello, world: here % is the shell"s output to i(cid:374)di(cid:272)ate the start of a (cid:374)e(cid:449) (cid:272)o(cid:373)(cid:373)a(cid:374)d, (cid:272)alled prompt. : specifies a sequence characters, called a string literal. If runs without errors, it was successful in compiling. Syntax errors: errors that are found where the code does not conform to the required format, the execution of compilation (javac) informs of the error, for example: Spelling errors: use of reserved words, unbalanced braces, missing semicolons, missing magic word static Solution: attach a backslash in front of the second to inform java that it is not the double quote that is to surround the characters to be printed as in.
