Java Eclipse: Skip lines (NOT IN DEBUGGING)

Question

In Java code, is there a way to have the program "skip" lines of code (NOT during debugging)? ex:

if ( userInput.equals("one") ){
   Skip to line 82
} else {
continue to next line

How would Java have to do that? If on line 83 a method is declared, like, for example, `public void test() {` and line 84 contains `doSomething();`, then line 84 cannot be reached without passing line 83. — MC Emperor, Dec 26 '14 at 02:22
By all that is sacred and profane do not implement `goto` in Java. — Elliott Frisch, Dec 26 '14 at 02:25
Sorry, I meant how would I use a function to skip lines depending on what happens in the code before the function? — Brian Barone, Dec 26 '14 at 02:26
Yes, write methods, write branching code with `if` or `switch` statements. — MadProgrammer, Dec 26 '14 at 02:29
AAHHHH makes sense! Thanks for giving me the lightbulb MadProgrammer! — Brian Barone, Dec 26 '14 at 02:32

Just replace the condition with its logical negative, and move everything between the "next line" and line 82 (in your example) into the block.

if(!userInput.equals("one")) {
    //Next lines, up to your old line 81.
}
//Line 82.

In most languages, this Skip feature is implemented as goto.

Java made the concious decision not to include this in its language because it can enable bad code.

See

You can always comment over lines, but you made it clear its not for debugging purposes.

Instead, use if

      if(condition){<whatever you would have had between here and 82>}.

If condition evaluates to false, the lines will be skipped.
