Sep 11, 2014

I will like replace this code:

// boucle pour les fractions aleatoires
for (i=0; i<2; i++) {

// Creation des fractions aleatoires
Frac first = new Frac(r,5);

GPA Calculator In Java Using Loops And Switch

Apr 25, 2015

I am trying to make GPA calculator. I decided to use only switch statement and make it as simple as possible. The point is to enter as many classes and students as user wants. I keep getting credit points 0 at the end and also text format is not good too. Here is the code.

import java.util.Scanner;
import java.io.*;
public class SwitchExercise{
public static void main(String[] args) {
String grade = "";
String grades="";
String coursename="";
String headingleft="COURSES";

[code]....

How To Replace Letters

Oct 15, 2014

I can't figure out why my code doesn't work. My task is to replace for example ä=>ae, using this method String.charAt(int index). So here is my code:

public class pich {
public static void main(String[] args) {
String text = "Die süße Hündin Leica läuft in die Höhle des fülligen Bären "+
"Iliyan (ein Übergrößenträger), der sie zum Teekränzchen eingeladen hat."+
" An ihrem Öhrchen trägt sie modisch eine Ähre.";
String textOhneUmlaute = "";

[Code] ....

when I launch my code I get the same String and nothing has changed

Replace Negative Zero With Zero When Printing?

Mar 2, 2015

How do you replace negative zero value with a zero value when Printing results:

I want to remove the minus sign in -0.0000 and instead have 0.0000.

I am Printing coordinates and I do not want to have negative zero.

the coordinates are defined as double.

System.out.format(java.util.Locale.US," %.4f %.4f %.4f %.4f%n"xCur ,yCur,xNext,yNext);

0.0000 1.0000 -0.0000 0.0000

Replace Unless Inside Quotes?

Aug 24, 2014

Basically, I am trying to write a method that will take a string, a target, and a replacement (a replacement function like string.replace). I want it to replace all instances of target with replacement EXCEPT for instances that occur within single or double quotes.

Example input / output:

this "Wont" be " replaced, be"

call: replace(theString, "replaced", "narf") and replace(theString, "be", "rafn")

output:

this "Wont" rafn " replaced, be"

2D Arraylist Replace Specified Elements

May 11, 2015

I have a 2D arraylist, named as adjLists, which contains arraylists, containing values like these. Each two values are a "pair" and each third is a "flag" for the pair.

[278, 106, 0, 397, 36, 0, 59, 208, 0, 366, 221, 0]
[366, 221, 0, 397, 36, 0, 132, 390, 0, 278, 106, 0, 295, 0, 0]

I use code above to search for specified value pairs in these lists. vertexnum is the number of "sub arraylists" in adjLists.

for (int l = 0; l < vertexnum; l++) {
if (adjLists.get(l).get(0) == p.x && adjLists.get(l).get(1) == p.y) {
for (int h = 0; h < adjLists.get(l).size(); h += 3) {
for (int g = 0; g < vertexnum; g++) {
if ((vertexSprite[g].getX() + vertexSprite[g].getWidth() / 2) == adjLists.get(l).get(h)

[Code] ....

This code is to search exact values and replace their flag in every occurences. It can not find all the occurences of the values/pair in the lists, it replaces flag value only a few time. Value of score should be incremented with plus 1 after each found occurence, but this code increments it more than the number of matches.

Replace Correct Number Into Letter?

Mar 8, 2014

I'm trying to figure out the correct way to replace number into letter. In this case, I need two steps.

First, convert letter to number. Second, restore number to word.

Words list: a = 1, b = 2, f = 6 and k = 11.

I have word: "baafk"

So, for first step, it must be: "211611"

Number "211611" must be converted to "baafk".

But, I failed at second step.

Code I've tried:

public class str_number {
public static void main(String[] args){
String word = "baafk";
String number = word.replace("a", "1").replace("b","2").replace("f","6").replace("k","11");
System.out.println(word);

[Code] .....

Result for converting to number: baafk = 211611 But, result for converting above number to letter: 211611 = bkfk

What do I miss here?

How to distinguish if 11 is for "aa" and for "k"? D

How To Replace Author Names With Numbers

1992,C_BURGESS,J_CLINE,M_LUTY
1992,M_DINE,R_LEIGH,P_HUET,A_LINDE,D_LINDE

I want the result to be sth like this:

1992 1,2,3,4
1992 5,67
....

and a table of mappings

M_DINE 1
R_LEIGH 2

....

I give my dataset in csv (or text) format to my program but it says "(The system cannot find the file specified)" even though the file exists.

what should I do?

here is my code:

Java Code: public class ReadCSV {
HashMap<String, Integer> authorList = new HashMap<>();

While Loop - How Result Being Replace If It Only Equals To 1

Jul 6, 2014

I was reading a book and came across this while loop.

public class Powers {
public static void main (String [] args){
int e;
int result;
for(int i = 0; i < 10; i++){

[Code] .....

This loop presents the following (I'm sure it's not necessary):

2 to the 0 power is 1
2 to the 1 power is 2
2 to the 2 power is 4
2 to the 3 power is 8
2 to the 4 power is 16
2 to the 5 power is 32
2 to the 6 power is 64
2 to the 7 power is 128
2 to the 8 power is 256
2 to the 9 power is 512

I am just having a difficult time understand and grasping this concept. My main issue is result *=2; this is making it very difficult to understand. How is result being replace if it only equals to 1.

Built In Find And Replace Method For Strings In API?

Jan 26, 2015

I am wondering if there is something similar to the "Find and Replace" action, that we use in applications like Eclipse and MS Word, that is actually built into the Java API so we can use it in our code, mainly for method names?

For example, right now I have these couple of lines

rotateLeftCounterClockwise(1);
rotateBottomClockwise(1);
rotateLeftClockwise(1);

//and

rotateRightCounterClockwise(1);
rotateBottomCounterClockwise(1);
rotateRightClockwise(1);

that does one operation for a side of Rubik's cube. However, all other sides of the cube can use these same exact code with the exception of the 2nd word, ie the position, in each method.

So for example, another side would do something, like, lets say

rotateFrontCounterClockwise(1);
rotateBottomClockwise(1);
rotateFrontClockwise(1);

//and

rotateBackCounterClockwise(1);
rotateBottomCounterClockwise(1);
rotateBackClockwise(1);

The reason why I ask this is because this would DRASTICALLY shrink the size my code, rather than have to create separate methods for each operation. Now I know there is a Find and Replace feature for Strings, but I am not sure about method names...

Java Regular Expressions - Simple Search And Replace

Mar 1, 2014

I want to do a simple search and replace regular expression of lines. I am very unfamilar with Java regular expressions, and I'm not sure how to do something as simple as what I want to do. I have lines that look like this...

Java Code : access_log /home/%USER%/access_log mh_sh_highlight_all('java');

I want them changed so %USER% changes to a string, such as "cyrus," so they appear like this ...

Java Code: access_log /home/cyrus/access_log mh_sh_highlight_all('java');

The reason I want to use regular expressions is because I want to use the replaceAll method of the java.lang.String object. If I use replace I have to convert my strings into char arrays, and my code becomes bulky.

Replace All Command That Is Found On String Between 2 Double Quotes?

Mar 17, 2014

how to replace all the command that is found on a string between 2 double quotes? for example I have a text file that contains data like as following
 
A,"-16,12","-178,245","-15,506"
B,"-16,12","-178,245","-15,506"
C,0, 0,1
 
I need an output like this:
 
A,"-16.12","-178.245","-15.506"
B,"-16.12","-178.245","-15.506"
C,0, 0,1
 
I did this but without regular expression. It seems to me that a regular expression it's more elegant than to parse every line and replace it.

Can Database Storage And Queries Replace All Collections And Arrays (which Basically Hold Data)

Jan 10, 2014

My friends and me are trying to make online Test taking system. We got a very basic doubt.

We have developed classes and relationship between classes for example : Online Test Taking system will have admin and student class. And Admin will have list of students.. etc.

But question troubled me was: if we use database to store all data for example student details then I can perform all sorts of operations writing sql query and store result in some other database then what is the need of "ArrayList<Student> field in Admin".??

Question is: We can put everything in database and manipulate using database(sql) functions to manipulate it.Then what is the need of Arraylist of anything which is just used to store object details for example student details....??
