Writing A Program That Searches Array Using Binary Search

Jul 10, 2014

I'm (failing at) writing a program that searches an array using binary search, but I can't get it to work.

My code so far is this:

Java Code:

package sorting;

import java.lang.*;
import java.util.*;
public class sorteh {
public static void main(String [] args){
int[] array=new int [20]; //creates new array
for (int x=0;x<array.length;x++){ //populates array
array[x]=x*3+1;

[code]...

I copied what a website did for the sorting part, but if I have low=0 and high=19, wouldn't mid not be an int?

Inventory Program - Add / Delete / Modify / Search And Save

Feb 15, 2015

The goal was to add a few buttons an add delete modify search and save. I feel like I have the entire need satisfied. I'm having a few symbol problems which I'm not quite sure how to fix.

My full code is:

import javax.swing.*;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.awt.event.*;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;

[Code] ....

which is directing me towards Prodname on the far right of the if statement. I'm not sure what the problem is. I've double checked my spellings several time for each spot and I cant quite get it.

Everyone has told me but I am aware that I made some bad decisions with the variables being capitalized this was my first go at a program and my instructor didn't let me know that thats the normal way to do it.

Ability To Search A Binary Search Tree And Return The Number Of Probes

Sep 1, 2014

I'm trying to build a method that can search a binary search tree for a specific target and then return the number of probes it took to get there. It seems to me that the best way to do this would be a recursive search method and a counter that tracks the number of calls. But I'm struggling with how to implement this. Here's the code I have so far. what works/doesn't work with the method.

// Method to search the tree for a specific name and
// return the number of probes
public T search(BTNode<T> btNode) {

Treemap Partial Key Value Search

Apr 3, 2015

Knowing that a hashmap does not sort the keys, I am thinking of using/converting to treemap which by nature does sort out the keys. I now need to find out if it is possible to search a treemap using partial keys such that for example I would like to search for all entries that have a key starting with "78BOX" whilst the available keys are:

75SQUARE3
76DIAMOND2
78BOX26
78BOX99
78BOX300
79TRIANGLE4

The above list is probably how treemap would sort out the keys however need to extract only those keys that start with "78BOX" - does treemap has this functionality ?

2D Arrays - Word Search?

Dec 14, 2014

Okay, so the assignment was creating a word search for the given array. I've created all the code necessary, but I've ran into trouble. This problem occurs with the Up-Forward, Up-Backward, Down-Forward, and Down-Backward sections. If I only set one of these to run, it works. But if I have all 4 set at the same time, it errors out on the first one that runs.

public class P_WordSearch {
public static void main(String[] args) {
char[][] puzzle = {
{'B','O','O','G','S','R','O','W','I','N','G'},
{'E','B','L','G','N','I','M','M','I','W','S'},
{'L','C','E','A','T','I','P','U','P','I','S'},
{'C','M','I','N','C','A','X','Y','O','S','N'},

Aug 12, 2014

I am inputting a file that has the system output when pinging an ip address. i have gotten it to read the file into an arraylist with readLine. Is there a way to have it input to list using spaces instead of lines?

BufferedReader bf = new BufferedReader(new FileReader(file));
int linecount = 0;
int numberTimes = 0;
String line;
//loop thru file and add contents to an arraylist
while ((line = bf.readLine()) != null) {
inLine.add(line);
}
bf.close();
System.out.println(inLine);

get the arraylist to hold it like this:

(0)Pinging
