    <p>newbie here i have written a code to search for words in a puzzle but the word search does not seem to return anything after i run the program. i stored the dictionary in a binary tree. i need to check the every combination of characters against that in my tree.Could you please help. Thank you....</p> <p>this is the solve method</p> <pre><code>public String solve() { int row = puzzle.length; int coloumns = puzzle[0].length; this.foundWords = new ArrayList&lt;String&gt;(); if (this.dictionary == null) return null; for (int i = 0; i &lt; this.puzzle[0].length; ++i) { for (int j = 0; j &lt; this.puzzle.length; ++j) { if (this.getWord(i, j, 0, 1) == null) continue; if(this.inDictionary(this.getWord(i,j,0,1))) this.foundWords.add(getWord(i,j,0,1).concat("\n" + this.mapDirection(0))); for(int d = 0; d&lt;8; ++d) { int n = 2; String word = this.getWord(i,j,d,n); while(word !=null) { if(this.inDictionary(word)) this.foundWords.add(word.concat("\n" + this.mapDirection(d))); word = this.getWord(i,j,d,n); n++; } } } } String temp = ""; for(int i= 0; i &lt; foundWords.size(); i++) { temp = temp.concat(foundWords.get(i)); } return temp; } </code></pre> <p>this gets the word..</p> <pre><code>public String getWord(int row, int column, int d, int length) { if (length &lt; 1) return null; d %= 8; StringBuilder rBuild = new StringBuilder(); rBuild.append(this.puzzle[row][column]); length--; while (length &gt;= 0) { if ((d == 3) || (d == 4) || (d == 5)) column--; if ((d == 1) || (d == 0) || (d == 7)) column++; if ((d == 1) || (d == 2) || (d == 3)) row--; if ((d == 5) || (d == 6) || (d == 7)) row++; if ((row &lt; 0) || (row &gt;= this.puzzle.length) || (column &lt; 0) || (column &gt;= this.puzzle[0].length)) return null; rBuild.append(this.puzzle[row][column]); length--; } return rBuild.toString(); } </code></pre> <p>for the direction..</p> <pre><code>public String mapDirection(int direction) { direction %=8; switch(direction) { case 0: return " right"; case 1: return " up and right"; case 2: return " up"; case 3: return " up and left"; case 4: return " left"; case 5: return " down and left"; case 6: return " down and left"; case 7: return " down and right"; } return null; } </code></pre>

    2. COwhen i run a search, nothing happens, no exceptions, no strings are displayed just nothing. if i edit temp and change it to a string i see the string, so this tells me foundWords seems to be empty.

    3. CODoes the development environment not allow you to step through your code line by line?? If it doesn't then add a bunch of logging functions to see where it's going and what it's working on.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
