Aug 1, 2014I was just wondering about the equivalent of c function getchar() in java? I am trying to assign letters to array elements through input stream. A simple code in java that matches this code:

for(i=0; i<10; i++){
array[i] = getchar();
}
for(i=0; i<10; I++){
putchar(array[i]);

How To Get Java Equivalent Of C++ Constant
Jun 10, 2014How to make sure that a variable passed to a method isn't altered by the method? I know in C++ you can do something like
void aMethod(const Object &item) {
........
}
I know that you can stop a variable from being reinitialized in java by doing this
void aMethod(final Object item) {
.........
}
However, that won't stop it from calling a setter on the item or changing something in it. Is there some other keyword out there that can do this? I just found that java DOES recognize the const keyword but that it really is useless.
So, any practical way that const can be further approximated in java beyond using final?

Match RegEx Equivalent Of Contains?
Oct 4, 2014In a code im writing I was curious as to instead of
contains(".")
I wanted to use
matches(" ") method instead but really having issues with the regex
I have tried //. as well as ^[.] but they give me errors.
I am just trying to match a period but was curious as to what the form was. I read a good amount of materials and seemed simple but getting errors.
Integer Variables - Which Three Logical Expressions Are Equivalent To Each Other
Apr 12, 2014Assuming that x, y, and z are integer variables, which of the following three logical expressions are equivalent to each other, that is, have equal values for all possible values of x, y, and z?
(x == y && x != z) || (x != y && x == z)
(x == y || x == z) && (x != y || x != z)
(x == y) != (x == z)
None of the three
A. I and II only
B. II and III only
C. I and III only
D. I, II, and III
I selected B, but got it wrong. I really think I need understanding boolean logic. The correct answer says something else but I don't get the logic. Here is the correct answer:
Answer Key : The following model answer has been provided to you by the grader. Carefully compare your answer with the one provided here.
Expression III is the key to the answer: all three expressions state the fact that exactly one out of two equalities, x == y or x == z, is true. Expression I states that either the first and not the second or the second and not the first is true. Expression II states that one of the two is true and one of the two is false. Expression III simply states that they have different values. All three boil down to the same thing. The answer is E.
In exercise 4, I get the same problem:
The expression !((x <= y) && (y > 5)) is equivalent to which of the following?
A. (x <= y) && (y > 5)
B. (x <= y) || (y > 5)
C. (x >= y) || (y < 5)
D. (x > y) || (y <= 5)
E. (x > y) && (y <= 5)
Exercise 4

Your answer is incorrect.
Answer Key
The following model answer has been provided to you by the grader. Carefully compare your answer with the one provided here. The given expression is pretty long, so if you try to plug in specific numbers you may lose a lot of time. Use De Morgan's Laws instead:
!((x <= y) && (y > 5))
!(x <= y) || !(y > 5)
When ! is distributed,
&& changes into ||, and vice-versa
(x > y) || (y <= 5)
Equivalent Arrays - Comparing 2 User Inputs To Determine If Same
Mar 4, 2015I have been stuck on this for the past 2 hours, basically we have to compare user input, put user input into an array and compare for equivalency. An example of the program:
Array 1: 1 2 3 4 5 6 7 8
Array 2: 1 2 3 4 5 6 7 8
Array 3: 1 2 3 4 5 6 7 8 9
Array 4: 1 2 3 4 5 6 7 8
Array 1 & 2 are equal
Array 1 & 3 are not equal
Array 1 & 4 are not equal.
This cannot be done by importing Java.util.Array at all!! (my research only find this to compare arrays ) which is why I am having trouble starting off. My code thus far:
import java.util.Scanner;
public class Lab07b {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter Integer 1:");
int a = input.nextInt();

GUI Java Program - Hex To Binary Converter
Mar 11, 2014This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.
The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.

Java Binary Tree Code
Apr 5, 2014 I have written a code to get all the nodes below a current Node and it is working but I need to get it to look better if possible. To get the number of nodes below I have created an Array List, which I then go to the first Node below and add all the people to the Array list on the same level till I get to the end of the level, then I go down again until I cannot go down any more. Is there a way I can have my code without having to use an array List? I have put my code below. The brieff about the tree is that you have a parent and below the Parent are children who can have brothers and sisters next to them and after that they also have children below that. The method is trying to find the number of children below any given child
private LinkedList<Node> TempQueue = new LinkedList<Node>();
public int noOfYoungerChildren(Member p1){
Node tmp = find(p1);
return countYoungerChildren(tmp);

Why There Is No Literal Representation For Binary Numbers In C / C++ Or Java

Read Binary Unix File With Java?
Jan 24, 2014I have a unix program that simulates an accident evolving as a function of time and produces two files. I will focus on the first file before getting to the second. This first file has five output variables/vectors (velocity vs time, pressure vs time, etc), which are selected as part of the simulation input. These are the variables I have to put into Excel if I want to view the transient graphically. Where it gets tedious is that, if I want to view a different set of five variables, I have to rerun, extract, put these in Excel to plot. There can be lots of variables needed to properly characterize the accident.
The second file produced is a really large binary file. This file contains all the information that I'd need, precluding the need to rerun to view a different set of output variables. This is the file that seems tailor-made for a Java or something to be able to extract the information. That is, it seems like Java could be used to do this work: extract variable information from the large binary file. Eventually, I would like to plot it too and I know I could use Java there.
I think my steps are:
1) understand the format of my binary file
2) reconfigure the binary file for use with java (is this demuxing?)
3) learn java programming for this application: extracting information to produce something like a .csv file with time on the leftmost column and variable information populating the rest of the columns.

Constructing Expression Trees In Java By Using Binary Search Tree
May 6, 2014I Write a Java program to parse a syntactically correct arithmetical expression and produce an equivalent Expression TREE. Remember, in an expression tree the terminal nodes are variables and constants, and the interior nodes are operators (such as +,-,*,/).
For instance the expression: (1 + 2) * 3 can be represented by the following tree:
INPUT Expression
(1 +2)*3
POSTORDER Expression
1 2 + 3 *
TREE [root=asd.reg.Node@56ddc58]
