regex - Equation Expansion -


i've requirement i've simplify equation.

i've input like,

and i've simplify equation a + bce + bcf + bde + bdf + x

make note that, there no numerical values assigned. i've simplify string equation , result in form of equation variables shown above.

currently, made stack kind of structure keep pushing in every character until encounter "+". once do, dump variables bottom top , remove elements stack until previous opening bracket ( on stack. until closing bracket @ remove until opening bracket previous 1 got closed.

however, trouble arises when i've (a+b)(e+f). unable come logic that. clueless on how i'll handling redundant brackets, ((a+b))

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
