I have it where it displays the top half of the diamond. But i cannot figure out how to get it to draw the bottom half.

Making Patterns (Diamond Shape) Using Nested Loops
Mar 23, 2015I have to make a pattern that is of a diamond shape such as this:
Java Code:
1
1 2 3
1 2 3 4 5
1 2 3
1
mh_sh_highlight_all('java');
I wrote this (for the variable name, this is just a small part of my program and I'm trying to get the pattern right so I didn't mind my variables at the moment):
Java Code:
public class NewFile{
public static void main(String []args){
int k = 0;
for (int i=1 ; i<=5 ; i++) {
{ for (int h=2 ; h >= i ; h--)
[Code] ....
My output is the following:
Java Code:
1
123
12345
1234567
123456789
mh_sh_highlight_all('java');
I realize I should divide the code into a lower and upper triangle using two loops. However, I don't know how to break the first part. I did find the "trend" but I don't see how to implement it.
I/O / Streams :: Unable To Write Sample Data Into Newly Created File

Another strange thing is that when I tried inserting System.out.println calls for debugging, nothing prints out.

// stuff here
}

String dirString = System.getProperty("user.dir");

Activating Inverse Button On Sample Java Applet
Dec 10, 2014Nearly all of hte sample Java Applet is pre-made by the teacher. I'm running into the issue where, if I use the string arithmetic inverse method provided by the textbook, it refuses to recognize variables such as s1, s2, and i. So I'm now trying to use stringbuilder, and running into a similar issue. It doesn't recognize hte symbol "buffer". Under the "else if ( e.getSource() == inverseStr ) {" is where my code starts. The "Your Code Here" was put there by the teacher, and I'm just using it as an easy way to create blank lines if I delete a method that isn't working for me in the above section.
import javax.swing. * ;
import java.awt. * ;
import java.awt.event. * ;
public class HW07 extends JApplet
{
public void init() {
setSize( 400, 300 );
add( new MyGUI() );
[code]....
When I launch the applet in TextPad, there will be an Inverse button, and when I click that, it should reverse the word provided in the applet window, and show it in the inverse there. I had the StringBuilder working once, but it showed its result in a separate command prompt.

QUESTION: Write a Java program that reads 5 integers, each of which is in the range of 1 and 13 representing a simplified poker card with no suit. Your program should then print the ranking of the hand with card number(s) beside the ranking. The rankings to determine are Four of a Kind(4 of the 5 cards of the same rank), Full House(3 of the 5 cards of the same rank, and 2 cards of another rank), Straight(5 cards of sequential rank), Three of a Kind(only 3 cards of the same rank), Two Pair(2 cards of the same rank, 2 cards of another rank, and no card of either rank), One Pair(only 2 of 5 cards are of the same rank), and High Card(no two cards of the same rank). Some sample runs are:
input: 2, 3, 2, 2, 2; output: Four of a Kind(2)

Write Java Program That Asks User For List Of Names?
May 21, 2015I am trying to write a java program that asks the user for a list of names (one per line) until the user enters a blank line. At that point the program should print out the list of names entered, where each name is listed only once (i.e., uniquely) no matter how many times the user entered the name in the program. I am supposed to use an ArrayList for this problem.
My idea for a solution is to create an ArrayList<String>, read each name, i.e., line, entered and then to see if that name is already in the ArrayList. I created a for loop to check each element in the ArrayList but when I try to assign an element to a string variable I get the error "Type mismatch: cannot convert from Object to String". Not sure why that is happening because the ArrayList is defined as a String list.
Here is the code so far.

Write A Java Program That Reads A Positive / Non-zero Integer As Input
Aug 1, 2011Write a Java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant.
A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.For example, the number 6 is perfect, since 6 = 1 + 2 + 3, the number 8 is deficient, since 8 > 1 + 2 + 4, while the number 12 is abundant, since 12 < 1 + 2 + 3 + 4 + 6.
SAMPLE OUTPUT:
1.)Input N: 5
5 is deficient.
2.)Input N: 6
6 is perfect.
3.)Input N: 18
18 is abundant.
How To Write JAVA Program That Read Whole Number And Tell Decimal Place
Oct 10, 2014Ex. If I type 5943, the program will say
mill = 5
hun = 9
ten = 4

get the picture I had to translate the decimal value names from a different language.
This is what I have tried...,

import java.util.Scanner;//Permite el uso de leer el teclado del usuario
public class DeterminarValorDecimal//Nombra el documento
{
public static void main(String [] args)//Podemos ver la clase
{

But what this does is I have to enter the single digits one by one. I want to be able to type the whole number. Is there a method that reads the length of the whole number and lets me classify each digit so I can do what I want to do?
