String Split Method - Return Array Of Strings Consisting Of Substrings Splitted By Delimiters

Sep 28, 2014

I am having a problem with the following code. It compiles and runs fine however my output is wrong.

public class SplitString {
public static void main(String[] args) {
String[] string1 = split("ab#12#453", "#");
String[] string2 = split("a?b?gf#e", "[?#]");
for (int i = 0; i < string1.length; i++) {
System.out.print(string1[i] + ",");

[code]....

The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters.public static String[] split(String s, String regex)For example, split("ab#12#453", "#") returns ab, #, 12, #, 453 in an array of String, and split("a?b?gf#e", "[?#]") returns a, b, ?, b, gf, #, and e in an array of String.

Parse Value Of Array Of Object Passed Through A Parameter

Oct 29, 2014

I'm working on a method that would parse the value of the array of object that I passed through a parameter. I would like to ask if making Object as a parameter is doable. Let's say I have a class Student and Teacher. I created a class the would handle the sched and name it class Schedule and extend this class to the Student and Teacher. Now I want to have a function that will accept an array of Schedule from either Student and Teacher, what ever object I will pass in the parameter. I know its easy to just make a method with a separate parameter of my classes but im looking for a more dynamic code.

class Student extends Schedule{
//variables here for student
}
[code]

class Teacher extends Schedule{
//variables here for teacher
}
[/code]

private void parseObject(ArrayList<Object> objct){
Schedule temp = objct.get(0);
//there is no error in this part

}

Now when i will try to use the function and pass a data, it will not accept since my parameter should be an array of object. How would I twist dis one?

ArrayList<Student> temp_student = new Array....
parseObject(temp_student); // it will not accept my parameter, how would i make it as an object

Delimiters In String Split

Jun 10, 2014

I know adjacent delimiters create empty token but is there any exception regarding last pair of delimiters ??

String a[]=":ab::cde :fg::".split(":"); // Creates 5 tokens
String a[]=":ab::cde :fg:: -Space-".split(":"); // Creates 7 tokens

Aug 10, 2014

How can I access the index of one character array and store those indexes into another array? I need this array of indices so as to perform an addition with another array.

Suppose I have a char array that stores all the letters of the alphabet (say alpha) and I have an another char array (say letter) that contains some letters in it. I want to retrieve those letters from the "letter" array and check its index in the "alpha" array and store that index into another integer array.

How To Set Delimiters For Email That Is Saved As A Text File In Java

Jul 23, 2014

I have saved emails that are stored in to text files and I want to retrieve the Sender, Reciever, Subject and the Email Content.I am using From: as a delimiter and To: as a delimiter and Subject as a delimiter and I am not sure what delimiter I should set for the email content.Also, there can be emails that will have comments after the message content and I plan on using the delimiter Comments:.

Any example of what delimiters I should use it would be great. Also I would like to know how check whether or not a delimiter exists so that I can print out the comments if it exists and if the file does not have comments, it prints out nothing.

Checks Whether First String Is A Substring Of Second

Mar 22, 2014

(Check substrings) You can check whether a string is a substring of another string by using the indexOf method in the String class. Write your own method for this function. Write a program that prompts the user to enter two strings, and checks whether the first string is a substring of the second.

What the function should return

public class Ex2 {
public static void main(String[] args) {
System.out.println("Input the first string:");
Scanner input = new Scanner(System.in);
String firstString = input.nextLine();
System.out.println("Input the second string:");
String secondString = input.nextLine();
check(firstString,secondString);

Compare Substring With String?

Apr 22, 2014

Why isn't it working?

Java Code:

if ((line.substring(i,i+2)) == "go")
break; mh_sh_highlight_all('java');

I printed this to check if substring works fine, used this:

Java Code: System.out.println(line.substring(i,i+2) + " : "+ length); mh_sh_highlight_all('java');

So, output:

Er : 1

ra : 2

ag : 3

go : 4

on : 5

n' : 6

'> : 7

Line:

String line = "Eragon'>";

Shouldn't it break loop after printing "go : 4"?

line.substring(i,i+2) prints go here. But if doesn't work.

Using Substring Methods To Format Numbers Between 1,000 And 999,999

Mar 20, 2015

Write a program that reads number between 1,000 and 999,999 from the user and prints it without a comma separating the thousands. Read the input as string. Find the length of the string and use the substring to break it into two pieces. Do not include the comma. You can then concatenate using the + symbol to reassemble without the comma. For example if the number is 123,456. First would equal 123 and second would equal 456. noCommaNumber - 123456.

I do not think it is required to only allow numbers in that range in the code. My question is how to get the first half of the number before the comma in a string to make the last line work. What I think is not doing what I need is the line String first = numberIn.substring(numberIn.indexOf(",", 0)); This is just the last thing I tried.Getting the second half is done using IndexLastOf method in the substring class javaforumquest.jpg

Why Substring Method Subtract Extra 1

Sep 10, 2014

Why does the substring method subtract an extra 1?

For example:

myString = "Programming and Problem Solving";

myString.substring(0, 7) would be "Program" instead of "Program".

It's not explained in the book I'm reading and didn't see it online.

Substring Of String Separated By Commas

Dec 29, 2014

I am trying for a logic that i have some emp ids as a string seperated by commas and i need the substring of emp ids as below. splitting the string as below.

public static void main(String args[]) {                 
String empId = "1,2,3,4,5,6,7,8,9,10";       
int i;
int count = 9;
for (i = 0; i <= count; i = i + 3) {            
System.out.println("Emp IDs are : " +empId);          
}}

Result is:

Emp IDs are : 1,2,3,4,5,6,7,8,9,10
Emp IDs are : 1,2,3,4,5,6,7,8,9,10
Emp IDs are : 1,2,3,4,5,6,7,8,9,10
Emp IDs are : 1,2,3,4,5,6,7,8,9,10
 
But I want the result like:

Substring Method And Singly Linked List

Jul 16, 2014

I'm still working with the singlylinkedlist data structure and trying to return a string of individual characters stored in each node. ( head--('J')---('A')---('V')---('A')---tail ) Hopefully this beautifully executed depiction to the left will clarify.

This is what I came up with after designing the algorithm w/ pen and paper. I know that I'm not accounting for the OutOfBound errors, an empty list, or an index < 0.... I will get to that.

Right now, I'm not sure why my assignment to the character array, ' chars[i] = cursor.getLink(getElement()); ' , is not working. The two methods getLink and getElement, type Node and T, respectively, exist in my Node class which is a private nested class in MySLList. Why would I be getting the following error: "The method getElement() is undefined for the type StringX" ? Is this a good design and implementation of the substring method?

public String substring(int index) {
char[] chars = new char[(getSize() - index)]; //getSize() defines the size of list in MySLList
Node cursor = null;
//Set the cursor to the node = index
if(cursor == head) {

[Code] ....

Write A Program To Create Integer Array Of Size 20

Aug 2, 2014

Write a program to create an integer array of size 20. Then, the program should generate and insert random integers between 1 and 5, inclusive into the array. Next, the program should print the array as output.

A tremor is defined as a point of movement to and fro. To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.

Then, the final array should be printed as output. There is no user input for this program.Your program must include, at least, the following methods:

-insertNumbers, which will take as input one integer array and store the random numbers in it.
-createTremor, which will generate the random number as the location and return it.

A sample run of the program is shown below:

Sample output #1:
Array:1 2 2 3 1 5 4 2 3 4 4 2 1 1 3 2 1 4 3 2 1
Random position: 5
Final Array:1 2 0 0 0 5 0 0 0 4 4 2 1 1 3 2 1 4 3 2 1
