Can't Execute Shell Script Called From Java Class
Apr 7, 2014
My java class doesn't execute a shell sript, I had given the java io file permission read and execute over the script shell to the user who execute the java class, also I executed the script shell in the console each RAC server using oracle user session and the srcript shell works. My team DBA told me that " The user server process is oracle". My script shell resides in all RAC server file system the last result looks as follows:
/home/mydir/dir2/mybin/compacta_archivo.sh
No Funcionando!!
java.io.IOException: /home/gi91591/reppostpago/bin/compacta_archivo.sh not found
[Code]....
of course, the script file exist on my file system, it has the suitable permission as the test result i got each time I executed on the console. My Oracle version is 11.2.0.3.0 on Rac ASM.

i am trying to write a coin program:Write a class called Coin which will be used by a program called CountFlips.
1. The class, is an object created from this program. It is composed of data values and methods. It should contain a main method and should output the number of flips done (an integer that will be read from the user), the number of heads and tails that occur.
2. The CountFlip class will flip a coin multiple times and counts the number of ‘heads’ and ‘tails’ that result. This class should have a method called flip() of type void; a method called isHead() of type Boolean and a toString() method that will return the current face of the coin as a string.
So i created 2 classes, one called Coin.java & the other CountFlips.java,
PHP Code: package test;
public class Coin {
private final int heads = 0;
private final int tails = 1;
private int facetype;
private int flips;
[code]....

I have few queries regarding compiling v/s execution of a java program. Suppose I have a Main Class which is referring to class Test which is present in JarA. Now, at compile time, this jar JarA must be present in classpath/buildpath. So, what actually is the action performed by the compiler by referring to this jar?
Now, at runtime also, this jar should be present to execute the Main class. Is this correct? If yes, then what is the action performed by JRE when it refers to this class at runtime? WOn't all the dependencies be resolved at compile time only?

I created my button so it can't be unselected. The problem is I have the button in a Class.java and I want that to close in a period of time. What do you recommend using?

Write an instance method, contains, that has one explicit parameter of type Rectangle. The method should return true if every point of the rectangle determined by the explicit parameter is on or within the rectangle determined by the implicit parameter. It should return false otherwise.
This is what i did so far?
public boolean contains(Rectangle other) {
Rectangle intersect = Rectangle.intersection(this, other);
if ((intersect.left == this.left) && (intersect.bottom == this.bottom) && (intersect.width == this.width)
&& (intersect.height == this.height)) {
return true;
} else {
return false;
}
}

I need to work on this "Dice" program. I've done it twice already. I've also been pouring over examples on here and elsewhere online, but none of them exactly match what I'm doing, as they all say "Pair of Dice".Mine says: "Create a class called Dice to represent a SINGLE cube". It should have a method called roll() that randomly selects a number from 1-6 for the value of the dice."
It has to use java.util.random, not math.java, and it has to have numberShowing:int, roll():int, and main() all in it.The last part reads "Create a test main method for the Dice class that creates a dice and rolls it many times. Can you keep track of how many times a number comes up? Describe how or implement it in the program." I have started at this computer for hours, and read as much info as I can.

I'm trying to make the program read the "Entity.sql" File and then execute it to make it run in phpmyadmin. I did used a mysql connector to link netbeans to mysql and then it should used the Connection for phpmyadmin to execute the Statement (Entity.sql).The Entity.sql file contains as sql Statement:
CREATE DATABASE IF NOT EXISTS Student
The problem is that it's not working and it's giving me this error:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
here is my entire code:
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.*;
import java.io.*;
import java.util.*;
[code]....
I want the program to first
1- Read the Entity.sql file
2- Execute the file into phpmyadmin

So when writing my first "Hello World" app everything seemed to work just fine. I wrote the code, compiled it, and then ran the class file and it worked, I got the return Hello World! But when I tried to write another app which is basically the exact same thing just a different sentence, I keep getting a bunch of error codes saying illegal character. I did everything the exact same. I am using Text Edit on a Mac and using Terminal to execute the Java code.
Here is what I wrote....
public class MyFirstApp
{
public static void main( String[] args )
{
System.out.println(“i rule the world!”);

I am making a program, where the user answers 3 questions and then I add the number of correct answers in to the (int) numberofcorrect variable, then I want to print the results, and no matter how many correct, the program executes first the correct if statement, then the else statement.
Eg: I have 2 correct it will print:
"Grade B, 2 of 3 "
"You failed the test"
Why does it do that? How can I change my code so the else statement dosent print if one of the if statments is allready printed?I want to know how to not execute the else statement, if one of the if statements have allready been executed.Below is my current code for this problem:
if (numberofcorrect == 3){
System.out.println("Grade A, full score");}
if (numberofcorrect == 2){
System.out.println("Grade B, 2 of 3 ");}
if (numberofcorrect ==1) {
System.out.println("Grade C, 1 of 3");}
else {
System.out.println("You failed the test"); }

Here's the code:

}
private static void foo(long a) {
System.out.println("long");
[Code] ....
This code prints long. Why is that? How did compiler decided that it likes long version of foo() method the most. If I had to guess I'd pick int... or possibly Integer as they are most similiar to what was passed. But why long?
