Java Programming

When a thread is created the threads does not require any new resources to execute the thread shares the resources like memory of the process to which they belong to. The benefit of code sharing is that it allows an application to have several different threads of activity all within the same address space. Whereas if a new process creation is very heavyweight because it always requires new address space to be created and even if they share the memory then the inter process communication is expensive when compared to the communication between the threads

Ellipses (...) used to emulate indentation... swap (int *i1, int *i2) { /* only works for integers, i1 != i2 */

... *i1 = *i1 ^ *i2;

... *i2 = *i1 ^ *i2;

... *i1 = *i1 ^ *i2;

}

The main method can be declared as either of the below: public static void main(String[] args)

or public static void main(String args[])

It gives you access to all of the IO file classes, including all of the stream classes and java.io.File.

Business Objects was created in 1990.

Let's use integers as an example.

int elementToFind; // the element we want to search for

int[] elementArray; // the array we want to search through

boolean found = false; //boolean flag to indicate if we found the element or not

for(int i = 0; i < elementArray.length; ++i) {

if(elementArray[i] == elementToFind) {

// we found the element at index i

// do whatever you want to do with this information

found = true;

}

//if found is still false so it means this element is not found

if(!found) {

//the element is not found in the array

}

}

An abstract equation is an equation where it is impossible, with the information given, to find the numeric values of the variables. For example 2X=4Y can be reduced to X=2Y or Y=X/2 or 2=X/Y but you cannot find the numeric values of X or Y.

You are supposed to use the same name for the filename and the class name. I am not entirely sure what happens otherwise; at the very least, I would expect that you would get unnecessary complications.

A string is, by definition, a character array. No conversion is required.

You cannot override a method inside the same class. If you do that, it is called Overloading. Experienced java programmers can clearly identify the difference between overloaded methods and the overridden ones. We just had a detailed look at overridden methods and it is time to take a look at the overloaded ones.

Overloaded methods let you reuse the same method name in a class, but with different arguments (and optionally, a different return type). Overloading a method often means you're being a little nicer to those who call your methods, because your code takes on the burden of coping with different argument types rather than forcing the caller to do conversions prior to invoking your method. The rules are simple:

• Overloaded methods MUST change the argument list.

• Overloaded methods CAN change the return type.

• Overloaded methods CAN change the access modifier.

• Overloaded methods CAN declare new or broader checked exceptions.

• A method can be overloaded in the same class or in a subclass. In other words, if class A defines a doStuff(int i) method, the subclass B could define a doStuff(String s) method without overriding the superclass version that takes an int. So two methods with the same name but in different classes can still be considered overloaded, if the subclass inherits one version of the method and then declares another overloaded version in its class definition.

As I know the search method depends on your(programmer's) logic. In sequential search it will be better to stop the search as soon as search value encounters or if search value is not in the array then it should stop at the end.

Sequential access basically means accessing things one after the other in order. For example reading all the numbers from 1 to 10 by starting at 1, then 2, then 3 etc.

1. #include
2. # include
3. char c1,c2,a[80];
4. void main()
5. {
6. clrscr();
7. find_rep();
8. getch();
9. }
10. void find_rep(void)
11. /* Function to find & replace any text */
12. {
13. char c1,c2;
14. char a[80];
15. int i,j,k;
16. printf("Enter a line of text below:-");
17. printf("Press Enter after line..");
18. printf("You Have Entred:- ");
19. gets(a);
20. printf("Enter the replaceable & replacing letter respectively:- ");
21. scanf("%c %c %c",&c1,' ',&c2); //i have given space & 2nd %c
22. for (j=0;j<80;j++)
23. {
24. if (a[j]==c1)
25. a[j]=c2;
26. }
27. puts(a);
28. printf("Here all %c are replaced by %c.", c1,c2);
29. return;
30. }

It depends on what the tree is being used for. If the tree is being used to store data that is not going to be modified very much, than AVL trees are probably better. In most other cases, I'd say Red-Black trees are better.

There are many different ways to print out a random sequence of letters on the screen. I believe that the shortest possible line of code that does this is:

System.out.println("abcdcba abc cba");

For a program, here is the shortest program that runs on a Java 1.6 compiler:

public class A{public static void main(String... a){System.out.println("abcdcba abc cba"

This is not a question.

Objects are classes... It's the most abstract type of data.

first class first class bigshots will go..Business class business freak junk heads will go..hehehehheheh

,

Strings are not a primitive data type and strings are objects of class String.

They have been built this way primarily because a large number of methods can be implemented for use if string is a class. That way coding regarding strings is much easier.

If you really want to implement it as a primitive data type, go ahead and create an array of characters. but then you wont be able to utilize all the string related methods in JDK
