Stack Overflow Error For Anonymous Class That Extend Interface
Jun 22, 2014
In the following program i have called the anonymous class of dev class.
interface emp {
void desig();
}
public class dev implements emp {
dev e = new dev() //this line is throwing error ...works fine if i use emp instead of dev {
[Code] .....
i am getting stack over flow error as :
Exception in thread "main" java.lang.StackOverflowError
at dev$1.<init>(dev.java:17)
at dev.<init>(dev.java:16)
at dev$1.<init>(dev.java:17)
[Code] .....
Is it because the jvm is not able to decide which of the 2 desigs() it has to load in the memory when its object is created in the main..??
I am getting a stack overflow error for my method that recursively gets the height of an AVL tree. The odd thing is that it returns the height of the tree the first time I call that method, but when I call it again later on, I get that error, which I does not make any sense to me. I have a base case, where it is supposed to stop when the node is null, but it never reaches that. Also, when I print out the values, it alternates b/w three values: 5, 4, and 24. Something else, which I think is important to state, is that if I put the print statement before my base case, the IF, I get a warning stating that my entire IF statement is dead code...but why?
is that everytime I insert/delete a value into the AVL tree I must make sure that it is height balanced (none of the siblings may have a difference in height from each other > 1); if its not height then I rotate certain nodes accordingly. The first 10 items that I input are: 100, 50, 24, 200, 190, 10, 5, 190, 100 and 4. The pre and in order prints of these, from the console are:
I am getting a stack overflow error. I know there's something off about the code but I can't get it....

I have an error using quicksort and this is a project ... The error occurs for numbers such as 7500 and bigger ...
Exception in thread "main" java.lang.StackOverflowError at QuickSort.QuickSort(QuickSort.java:45) at QuickSort.QuickSort(QuickSort.java:46) at QuickSort.QuickSort(QuickSort.java:46) ...
Java Code:
import javax.swing.JOptionPane; public class QuickSort{ public static void main(String[] args){ int p=new Integer(JOptionPane.showInputDialog("Jepni numrin e kufizave: ")); int[] ListaNumrave= new int[p]; //QuickSort Zbrites
I have wriiten a quick sort algorithm. I have used the last element as my pivot. The program is running for all sizes except for 100000 and 1000000 elements when they are sorted and unsorted list .
It shows me the error : Exception in thread "main" java.lang.StackOverflowError
I guess the memory gets out of space and we need to increase the stack size in eclipse. How do I increase the stack size in eclipse.? I tried increasing through run--run configurations-- program arguments and typed---- -Xmx4096m but this didn't work in any way.
I am new to java coding.... When we create anonymous inner class for interface, we get one object for the sublcass of that interface .
In interface there is no constructor then how do we get that object. We know that to create Anonymous inner class we should use one super class constructor.
how to 'implement' an interface and 'extend' a class. Now I want to try and recall the information by memory without using any reference material. Implementing an interface...
Java Code: //This interface will hold information for cell phones//Like saying... you can't BE a cell phone unless you have this information, at the very least
public interface CellInfo { public void model(); public void make(); public void androidVer();
}
//Now I implement the interface for a class called Galaxy, which is a class about a specific phone
public class Galaxy implements CellInfo public void model() { System.out.println("I'm a Galaxy S5."); }
public void make() { System.out.println("I'm made by Samsung.");
I can't figure out this problem that I'm having in my Pong game. It's compiling fine, except when I run it, it gives me an overflow error.
Here's the code:
// Pong import javax.swing.JFrame; import java.awt.Color; import java.awt.Graphics; public class Pong extends JFrame { private static final int WIDTH = 400; private static final int HEIGHT = 400;
[Code] .....
Here's the error:
java.lang.StackOverflowError at sun.awt.AppContext.get(AppContext.java:604) at com.sun.java.swing.SwingUtilities3.getDelegateRepa intManager(SwingUtilities3.java:120) at javax.swing.RepaintManager.getDelegate(RepaintMana ger.java:1625) at javax.swing.RepaintManager.addDirtyRegion(RepaintM anager.java:445)
The error keeps going for a lot of more lines.
The line that gets highlighted is the first bracket of the Pong constructor.
I am using the DJWebbrowser in a Java Swing Application that I am working on
// Browser addon as Panel JPanel browser = new JPanel(); browser = (JPanel) util.BPanel.createContent(); wrapper.add(browser);
and am sending data from a Google Map API , Distance Matrix Query with following code
function callback(response, status) { if (status != google.maps.DistanceMatrixStatus.OK) { alert('Error was: ' + status); } else { var origins = response.originAddresses; var destinations = response.destinationAddresses; var outputDiv = document.getElementById('outputDiv');
[code]...
I haven't found a way to access a class property from the class that invoked the web browser, because the above WebBrowserAdapter is in an anonymous Inner Class.´I would like to have the distance that is sent from the Javascript to the application be passed on to the class member "distance" that in the invoking class.
I want to extend hashCode method in my class. As we know that hashCode is generating with 32 bit. Now I wanna generate 64-bit hashCode for user given Input.. Input may be string or Integer.
Please let me know.. take me out from this problem..
MY code follows like this...
package hash_table; public class Hash_table { private int num; private String data; public boolean equals(Object obj) { if(this == obj)
I am working with a program where I am required to use a JFrame in a child class. The only way that I know how to access a JFrame is to do, example (public class Example extends JFrame), but since it is already extending the parent class, I am kind of stuck. I do not think that you can extend two separate classes, so..... I am stuck.
I am a beginner here at JAVA and I am trying to program a Gratuity Calculator using both interface class and object class but it keeps on compiling with errors saying "cannot find symbol".I tried everything to fix it but it just keeps on stating symbol.
[CODE] public class GratuityCalculator extends JFrame { /* declarations */
// color objects Color black = new Color(0, 0, 0); Color white = new Color(255, 255, 255); Color light_gray = new Color(192, 192, 192);
I want to create java program in which i want to inherit stack and queue from a linked list class and also make infix to postfix inherit from stack and periority queue from queue class.Ho can i make this program.
I know whats the interfaces and abstract class and also know that difference between interface and abstract class,but here my doubt is eventhough abstract class more advantage than the interface,then why should we use interfaces and when?
class Super { static String ID = "QBANK"; } class Sub extends Super{ static { System.out.print("In Sub"); } } public class Test{ public static void main(String[] args){ System.out.println(Sub.ID); } }
According to me output should be "QBANK" In Sub...BECAUSE sub default constructor will call super() constructor.. below is the definition in jls which i am unable to understand ....
A class or interface type T will be initialized at its first active use, which occurs if:
T is a class and a method actually declared in T (rather than inherited from a superclass) is invoked.
T is a class and a constructor for class T is invoked, or T1 is an array with element type T, and an array of type T1 is created.
A non-constant field declared in T (rather than inherited from a superclass or superinterface) is used or assigned. A constant field is one that is (explicitly or implicitly) both final and static, and that is initialized with the value of a compile-time constant expression . Java specifies that a reference to a constant field must be resolved at compile time to a copy of the compile-time constant value, so uses of such a field are never active uses.
All other uses of a type are passive. A reference to a field is an active use of only the class or interface that actually declares it, even though it might be referred to through the name of a subclass, a subinterface, or a class that implements an interface.
I know that we can create an inner class inside an interface but i want to know that why we'll create an inner class inside an interface. I mean what is the use of creating inner class inside an interface and what is the advantage of it.
