How To Concat Multiple Strings To A String Array

Dec 28, 2014

I am trying to update a Rubik's cubes side by adding each of the 9 squares of the Rubik's cube's side.

So for example:

cube.front.squares = cube.fronts.squares[1] + cube.front.square[2] + cube.left.sqaures[8] ... //until 9 sqaures are added, where squares is a String array of size 9. However, when I try doing this I get an error stating "change 'square' to 'String'". I know I can go in an individually change the values like:

cube.front.squares[0] = "whatever"
cube.front.squares[1] = "something else"

but I know there is a better way to do this...

I also just tried to use String[] concat= ArrayUtils.addAll(first, second) but that only takes in two arrays at most according to the API: [URL]...

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.

Create Separate String Objects As Strings Are Immutable

Jan 28, 2015

I want to clarify it whether this below code, when running this loop, will it create separate string objects as strings are immutable or else, will it keep the same reference(as each time inside loop, we use the same name 'rslt') and assign new string value for this?

while(inc < numberOfColumns){
String rslt=rs.getString(inc+1);
rowArr[inc] = rslt;
inc++;

Nested For Loops And Strings - Take A String As Parameter And Store It In S

Oct 11, 2014

Question: 1. Declare and implement a class named Substrings. The class will contain the following data members and methods:

Data members:
string S

Methods:
setS() take a string as a parameter and store it in S
printSub1(), printSub2(), printSub3(), printSub4() print all substrings of S. If S = "abcd",

printSub1() will print "a", "ab", "abc", "abcd", "b", "bc", "bcd", "c", "cd", "d",
printSub2() will print "abcd", "bcd", "cd", "d", "abc", "bc", "c", "ab", "b", "a",
printSub3() will print "a", "b", "c", "d", "ab", "bc", "cd", "abc", "bcd", "abcd", and
printSub4() will print "abcd", "abc", "bcd", "ab", "bc", "cd", "a", "b", "c", "d".

Alright so after doing some googling and watching tutorials I managed to put together the first two but I still don't exactly understand how nested for loops work, however just a single loop I do understand.

Secondly, the 3rd and 4th prints are completely destroying my brain using for loops, which we are supposed to use. Check out my code below, also keep in mind the 3rd is giving errors and the 4th i had to revert back to the same as the first print temporarily because my code because so messed up. How to understand nested for loops better.

[code=Java]

import java.util.Scanner;
class subString {
String S;
void setSubstring(String SS) {
S = SS;

[Code] .....

Compiling: error for myS.printSub3 and myS.printSub4 is the same as 1 because i had to revert it after ruining the code.

Compare 2 Strings - Generate New String With Matching Characters

Jul 3, 2014

I'm attempting a small program as I'm teaching myself the ropes. In it, I need to compare one string (the base) to another which is just the base string that's had it's characters shuffled.

Java Code:

String base = "ABCDEFG"
String shuffled = "CDAFBEG" mh_sh_highlight_all('java');

What I need to do is run a loop that shuffles the base string each time, but compares and saves any characters that match in the correct location. For example, if shuffled = "CDAFBEG", then the G would be "locked" in place and the rest of the characters shuffled and looped back to the comparison.

I have all the code I need for shuffling the string, but I'm not sure how I would go about comparing each character and then also locking it in place. I get the basics, I think, of needed to use several variables.

How To Get Average Of Strings Using Array

Apr 21, 2014

I'm trying to calculate the average of grades that a user puts in. Here is my code so far:

public static void main(String[] args) {
Scanner input = new Scanner (System.in); 
System.out.println("Please enter an array of grades seperated bt a comma.");
input.nextLine();
String arrayOfGrades = "100,50,100";
String[] grades = arrayOfGrades.split(",");
 
[Code] .....

I think I'm on the right track, the only big error I'm really getting is the line: sum += grades[i]. It's saying string can not be converted into a double.

Sorting Array Of Objects With Strings?

Feb 14, 2015

An array has objects with String firstName, String lastName, int ID, char examType('M' or 'F'), and int score. Every object has both Midterm('M') and Final('F'). The array has to be sorted by the first Midterm- 'M' and immediately followed by the Final ('F') of the same person (object). Im having troubles with coming up with a proper algorithm with gettin the Final- 'F' after Midterm for the same person.

Java Code: public static Exam[] collateExams(Exam[] exams) {
Exam [] r = new Exam[10];
r = exams;
int[] position = new int[10];
int index = 0;
for(int i = 0; i < exams.length; i++)

Sorting Array Of Strings From User Input

Apr 3, 2015

I am working on an assignment where I initially have to take as input a number. That number will be the number of strings the user is going to type. As they are typed, they are to be sorted alphabetically, then printed. It took me a while to get this far, and I am stuck on how to properly invoke the other methods in main. There has to be at least three methods: main, one to do the sorting, and one to print the new array. I'm quite sure there are mistakes in my code, but this is definitely a challenge for me. Here is the code. Keep in mind that the methods being invoked are blank on purpose.

I am not allowed to use the Arrays, Arraylist or Collection class. This is basically to test my ingenuity and to see how arrays actually work.

import java.util.*;
public class Sort_as_Inserted {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter number of elements to be sorted: ");
String element_number = input.nextLine();

Return Array Containing All Strings That Start With Letter A

May 13, 2014

Write a method that accepts an array of Strings.  The method must return an array containing all strings that start with the letter 'A'.  

There must be no 'null' values in the resulting array.  The resulting array may be of size zero.

I don't think I am returning ALL the strings that start with A, just the last one of the for loop. Does this look somewhat correct?

public String[] startsWithA(String[] strings) {
String startsWithA = strings[0];
for(int i = 0; i < strings.length; i++) {
if(strings[i].charAt(0) == 'A') {
startsWithA = strings[i];
}
return startsWithA;
}
}

I know you can use the split method, but I am not really sure how that wold work to perform math with them?

On a side note: for this application, how could you make the program accept a variety of different lengths of strings to perform math with them?

String Characters Display First Three Multiple Times

Sep 26, 2014

I am trying below challenge to display first three characters three times if the size of the string is greater than 3.

Say if i send hello i should get helhelhel

if i send xyz i should get xyzxyzxyz

I wrote as below

public String front3(String str) {
if(str.length()==3){
return str+str+str;
}
if(str.length()>3){
String str2=new String(new char[]{str.charAt(0),str.charAt(1),str.charAt(2)});
return str2;
}
}

I am getting error as below

Error:public String front3(String str) {
^^^^^^^^^^^^^^^^^^
This method must return a result of type String

Possible problem: the if-statement structure may theoretically allow a run to reach the end of the method without calling return. Consider adding a last line in the method return some_value; so a value is always returned.

How To Find Multiple Instances Of Same Letter In A Single String

I have got a pretty good framework working for my hangman game so far, however I am quite stumped on how to find multiple instances of the same letter in a single string.
