java - Simplifying an if-statment -

i have program few if-statements similar 1 i'm present you. wondering if guys me simplify equation in way. reason why ask because in notepad++, continues on 443 columns , it's frustrating edit if needed, , keeps getting longer keep adding variables. basically, example of 1 of many similar if statements, want action when of sliderbars try raise in value when int (rpg.statisticpoints) equal to, or less 0. method i'm using find out if sliders rising in value compare current value int associated slider, , check if result positive.

if (rpg.statisticpoints <= 0 &&  ((rpg.willslider.getvalue() - rpg.will) < 0) && ((rpg.perceptionslider.getvalue() - rpg.perception) < 0) &&  ((rpg.strengthslider.getvalue() - rpg.strength) < 0) &&  ((rpg.dexterityslider.getvalue() - rpg.dexterity) < 0) &&  ((rpg.constitutionslider.getvalue() - rpg.constitution) < 0) &&  ((rpg.charismaslider.getvalue() - rpg.charisma) < 0) &&  ((rpg.intelligenceslider.getvalue() - rpg.intelligence) < 0)) { //do actions } 

i understand there lot of variables here you're not familiar because didn't see full code, full source 100's of lines long , question based on logistics, , not issues syntax.

the problem current solution isn't long line, it's hard read , understand being validated.

instead of using conditions in if statement, can create auxiliary method build boolean value of validation, , @ same time give meaningful name.

for instance:

private boolean isvalidsomething(){      boolean result = firstcondition;     result &= secondcondition;     ...      return result;  } 

this way checks concentrated in 1 place, , lot more readable, since if become:

 if(isvalidsomething()) {...} 

of course, create method name makes sense in application.

in case you're validating several different conditions make sense separated, go mile , factor them out in own methods.

the main thing break logic pieces make sense together, like:

private boolean validstatistics() {      return statistics > 0; }   private boolean validwill() {      return > 0; }  .... 

and main validation like:

private boolean validcharacter() {      boolean valid = validstatistics();      valid &= validwill();      ...      return valid; }
