Delimiter Function And Number Of Words In String

Apr 20, 2014

Working on my java skills. The is Delimiter function is suppose to return true if there is a delimiter in the string and false otherwise. The main is suppose to call this function and count the number of words in the string:

Here is what I came up with:

import java.util.*;
 public class NumberOfWordsInString {
public static void main (String[] args){
Scanner in= new Scanner (System.in);
String s;

[Code] ....

Somehow my method isn't being successfully called by my main and the following error msg was received:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:

length cannot be resolved or is not a field

The method isDelimiter(char) in the type NumberOfWordsInString is not applicable for the arguments (char[])

at javaimprovements.NumberOfWordsInString.main(Number OfWordsInString.java:10)

line 10:
char ch [] = new char [s.length];

and the main doesn't call the isDelimiter function

How To Split String When Delimiter Also Is In The String

Mar 25, 2015

I have the the string value similar to the one   which i have to split based on the delimited ","
String SampleString=" 'ab,c', 'xyz', lm,n,o  "
 
I know I can easily call split function which will eventually split the above string. But in my case the delimiter ","  , is also a part of the string. If I call the function SampleString.split(',') I will get the output as listed below
 
ab
c
xyz
lm
n
o
but the expected  output is
abc
xyz
lmno

Finding Divisible Numbers And Replace With String

Jul 13, 2014

My interest in Java leads me to try and print numbers from 1-100. The output should show all numbers from 1-100 and each number that is divisible by by 13 should be replaced with a string "Fuzzy".

public class Fuzzy {
public static void main (String[]args){
for(int i = 0; i < 100; i++)
if(i % 13==0)
System.out.print(i + "fuzzy");
}
}

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.

This is my input from my text file: 1|John Jay Smith|1985-01-10|2010-05-10|2014-03-05|212-222-2233..So, I have to convert 1 to integer. Break John Smith into first name as John and Middle name as Jay Last name as Smith.If no middle name is given then first is John and Last is Smith . Read 1985-01-10 as a date value . 2010-05-10 as another date value which could be null. 2014-03-05 as another date value which could be null. and at last 212-222-2233 as phone number.

Scanner sc = new Scanner (inFile);
sc.nextLine();
while (sc.hasNext()){

String row= sc.nextLine();

I want to read this line of input and assign the value accordingly.

Delimiter - Type In 5 Strings From Java Console And Print Them All Out

Feb 13, 2015

I am testing some stuff here is my code:

public static void main(String[] args) {
String[] a = new String[5];
//String input = JOptionPane.showInputDialog(null, "enter input");
Scanner scanner = new Scanner(System.in);

[Code] ....

I am trying to type in 5 strings from java console and print them all out. I am using a "/" as a delimiter. My problem is that it does not print any output after I type strings separated by "/" like this: hello/gea/cae/eaf/aer and press enter. It works if I use JOptionPane but from the console its not working. I want to use the console instead of JOptionPane for this one.

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

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.
