i have: string s=" \"son of god\"\"cried out\" day , ok "; this shown on screen as: "son of god""cried out" day , ok pattern phrasepattern=pattern.compile("(\".*?\")"); matcher m=phrasepattern.matcher(s); i want phrases surrounded "" , add them arraylist<string> . might have more 2 such phrases. how can each phrase , put arraylist ? with matcher you're 90% of way there. need #find method. arraylist<string> list = new arraylist<>(); while(m.find()) { list.add(m.group()); }

i struggling figure out how code recursive algorithm count number of leaves in binary tree (not complete tree). far traversing far left leaf , don't know return there. trying count loading leaves list , getting size of list. bad way go count. public int countleaves ( ) { list< node<e> > leaflist = new arraylist< node<e> >(); //binarytree<node<e>> treelist = new binarytree(root); if(root.left != null) { root = root.left; countleaves(); } if(root.right != null) { root = root.right; countleaves(); } if(root.left == null && root.right == null) { leaflist.add(root); } return(); } elaborating on @dasblinkenlight idea. want recursively call countleaves on root node & pass # caller. on following lines. public int countleaves() { return countleaves(root); } /** * recursively count nodes */ private static int countleaves...

so writing in swift practice online judge. here's issue: longest palindromic substring given string s, find longest palindromic substring in s. may assume maximum length of s 1000, , there exists 1 unique longest palindromic substring. so using dp solve in swift: class solution { func longestpalindrome(s: string) -> string { var hash = array(count: s.characters.count, repeatedvalue: array(count: s.characters.count, repeatedvalue: false)) in 0 ..< s.characters.count { hash[i][i] = true } var maxstart = 0 var maxend = 0 var maxcount = 1 in 1.stride(through: s.characters.count - 1, by: 1) { j in 0 ..< s.characters.count - 1 { if j + < s.characters.count { if isvalidpalindrome(j, j + i, s, hash) { hash[j][j + i] = true if maxcount < + 1 { maxcount = ...

does know if there easy way use dependency injection within fxml controllers of gluon desktop (particleapplication) app? there @inject used things public class homecontroller { @inject particleapplication app; @inject private viewmanager viewmanager; @inject private statemanager statemanager; (as part of framework) able @inject own objects. edit: answer suggested use gluon ignite, i'm still having trouble figuring out. here of attempted code: my particleapplication class: package com.gluonapplication; import com.gluonhq.ignite.guice.guicecontext; import com.gluonhq.particle.application.particleapplication; import com.google.inject.abstractmodule; import javafx.scene.scene; import java.util.arrays; public class gluonapplication extends particleapplication { private guicecontext context = new guicecontext(this, () -> arrays.aslist(new guicemodule())); public gluonapplication() { super("gluon desktop application"); ...
