Creating Program That Will Estimate Child Height Based On Height Of Parents
Jun 19, 2014I am trying to create a program that will estimate a child height based on the height of the parents. It should ask the user to enter a String representing the gender, so m or M for a male and f or F for a female. The program must handle both upper or lower case gender entries. I need it to ask the user for the height of both parents in two parts:
1. for Feet and store in an int variable.
2. for inches and store and int variable.
So for example if the father is 6' 2'', the user would enter 6 when asked for feet and 2 when asked for inches. Convert the height of the each parent to inches. hint 12" in one foot.
Apply the following formulas based on gender (must use an if statement(s)):
Hmale_child = ((Hmother * 13/12) + Hfather)/2
Hfemale_child = ((Hfather * 13/12) + Hmother)/2
I cannot figure out what is missing from my code
<import java.util.Scanner;
public class ChildHeight
{
public static void main(String[] args) {
Scanner scannerObject = new Scanner(System.in);
String gender;
String male;
String female;

Finite Element In Java - Computing Stiffness Matrix For ISOTROPIC Case
Apr 2, 2014I build some finite element in java. I try to optimize my running time. I do some double loop and use inside the loop in if else statement and also in switch case .
The loop is very long, sometimes become ~500 X 500.
You think that if i avoid from the if statement and the switch case inside the loop i will improve the time calculation by at least 10%?There is something that i must to avoid ?
// Computing stiffness matrix.
switch (materialType) {
case ISOTROPIC:
// Computing stiffness matrix for ISOTROPIC case.
for (int row = 0, nvfi2 = nvfi * 2, index = 0, fieldsNvf = fields * nvfi; row < fieldsNvf; row++) {
if (row == nvfi) {

Palindrome Program - Java Stack And Queues
Aug 13, 2014I am trying to figure out stacks and queues and was trying to get this Palindrome program working so I could then play with it and use the Java visualizer site but for some reason the program isn't working correctly. It always states that the input is a palindrome no matter what the user input is.
The book that I got the code from is a little old so I changed a couple small things that I thought needed updating like adding scanner. I wanna use one with a custom array based stack and queue class rather than the java.util.Stack and Queue interface, just for understanding stacks and queues better hopefully.
import java.util.Scanner;
import javax.imageio.IIOException;

Numerically Computing Binomial Coefficient
Jan 29, 2015So I was given the program that calculates N!/[R!(N-R)!] and it has an overflow error after it passes N=18 and then starts spiting out incorrect answer. I'm supposed to figure out a way to protect the user from getting erroneous results when computing the formula (i.e. N!/[R!(N-R)!]).
HERE IS THE PROGRAM:
public class Combination {
private static final int defaultNMax = 30;
public Combination() {}
int compute(int N, int R) {
int i;
int numerator;
int denominator;
numerator = 1;

HERE ARE THE RESULTS IF YOU WANT TO SEE THEM:

N=2C(2,1)=2
N=3C(3,1)=3
N=4C(4,2)=6
N=5C(5,2)=10
N=6C(6,3)=20

Computing New String - Memory Out Of Heap Error

String replaceText = "";

replaceText = builder.charAt(i) + "*" + builder.charAt(i+1);
builder = builder.replace(i, i+1, replaceText);
}
}
return builder.toString();
}
}

The problem is, also when I have only one row in my jTable, the size of the jTable is a little more bigger than 40 rows.

I don`t want that the jTable is bigger than the content. For example the picture below:
Error When Trying To Set Changing Height Value From JFrame

The problem arises at the portion of the code that says
private int Y = game.getHeight() - 70;
I am not actually getting any compiler errors, but when I try to run the program, the command prompt pops up with this message:

What I want to do is make it so a GUI object that I created moves with the screen when I change the height. If I change it to private int Y = 330; the program works just fine.
GUI Bars - Increment Height By About 10 Pixels
Nov 12, 2014So I'm trying to make a bar graph, each bar will increment the height by about 10 pixels. To do this, I'm making an array of bars. For some reason, using fillrect I cannot not increase the size more than 10 by 10, if I do, it will only show the 10 by 10. I want the bars to increase in height by 10 each time.

Finding Height Of Binary Search Tree?
Nov 13, 2014So for an assignment I have to write a method that finds that height of this BST. I wrote this:
public int height(Node node)
{
if (node == null)
{
return 0;
}
else
{
return 1 +
Math.max(height(node.left),
height(node.right));
}
}
Which makes sense in my head. However, I added a couple of nodes in and realized I'm not sure how to call this method.
public static void main(String[] args) {
Tree<String, String> tree = new Tree<String, String>();
tree.add("A", "1");//some added stuff
tree.add("B", "2");
tree.add("C", "3");
tree.add("D", "4");
tree.add("E", "5");
tree.add("F", "6");
tree.add("G", "7");
tree.add("H", "8");
System.out.println(tree);
System.out.println(tree.height());
What exactly do I put in the parenthesis after tree.height? If you need to see more of my code I can do that but it is quite lengthy.

JavaFX 2.0 :: How To Dynamically Set Height Of Text Area
Jul 9, 2014I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description
TextArea textArea = new TextArea();
Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT

View Replies View RelatedReturn Height Of Heap Of Sand In Bottom Of Hourglass
Nov 18, 2014I am working on program and have been struggling to get around step 5 and 6 given below.
I have got on with the first couple of points. Where to begin with steps 5 and 6.
Java Code:
class Hourglass {
int height;
int bottomHalf;
public Hourglass (int h) {
height =h;
}
public Hourglass (){
height=3;
}
/*Write a method dropGrain that simulates one grain of sand falling into the bottom half of the Hourglass. If all the sand is already at the bottom before a grain is dropped, this method should cause the hourglass to be flipped, meaning that all the sand will be in the top again. Then, one grain of sand should fall. */
//Hint: this method can be quite short. All you need to do is update one attribute.
public void dropGrain(){
}
/*Write a method getHeapHeight() which returns the height of the heap of sand in the bottom of the hourglass.
Hint: a triangle of height h contains h*h grains (=1+3+5+...+h).
So determining the height when the amount of sand in the bottom half is a square (1,4,9,16,...) is easy. Think about what happens if the amount of sand is not exactly a square.*/
