Java Programming

I suppose you mean, tracing through your code.

Quite often, the program doesn't work exactly as expected; you may wish to see, step by step, what exactly your program does, to check at what point it works differently than what you had foreseen. Sooner or later, if you write more complicated programs, you will have no choice but to do this kind of follow-up.

No it is because compiled programs are scared so they run like stink.

Plus, uncompiled programs, ie. source programs, do not run at all... neither slowly nor fast.

yes we can define a variable in an interface in java.

I am also finding you can use this: System.out.println("\033");

I have checked it in Eclipse. Please check it in any other compiler/ IDE.

Sorry Doesn't work with my Java 6

Output -

/033

/033 : Your slash is the wrong way around ("\033", not "/033").

A Template in OO system refers to a skeleton or a framework or base pattern based on which further development is taken up.

import java.util.Scanner;

public class Numbers

{

public static void main(String[] args)

{

Scanner scan = new Scanner(System.in);

int max = -100;

int min = 100;

int sum = 0;

System.out.println("Enter ten integers");

for(int i = 0; i < 10; i++)

{

int input = scan.nextInt();

if(input > max)//test if the number entered is larger than any previous number

max = input;

if(input < min)//test if the number entered is smaller than any previous number

min = input;

sum += input;//add the input to the sum

}

System.out.println("The maximum number entered is: " + max +

"\nThe minimum number entered is: " + min +

"\nThe average of the numbers is: " + (sum / 10));//prints out the results

}

}

The keyword public is an access specifier. A variable or a method that is declared public is publicly accessible to any member of the project. Any class or method can freely access other public methods and variables of another class.

In procedural programming the programs are written as a list of instructions (procedures) which are written in a sequence, and where all programming is textual. In contrast, visual programming language uses graphics, animations....to manipulat programs without using texts....VLP is much easier than PP.

Private keys and their associated public-key certificates are stored in password-protected databases called keystores. A keystore can hold the keys of many potential signers. Each key in the keystore can be identified by an alias which is typically the name of the signer who owns the key. The key belonging to Rita Jones might have the alias "rita"

You execute it the same way you would on any other OS. As long as you have the Java Runtime Environment installed and the "java" executable is in your path, from the command line you would simply run: java -cp /path/to/file/here com.some.class.to.run.Here

Generally, a array is fixed in size. With some libraries, however, they are extensible, either by reallocation/copying strategies (C/C++/STL), or by linking/referencing strategies (JAVA).

well it was good that you came on the website but I don't know I was looking for the answer my self

import javax.swing.JOptionPane;

public class Addition

{

public static void main( String args[] )

{

String firstNumber =

JOptionPane.showInputDialog( "Enter first integer" );

String secondNumber =

JOptionPane.showInputDialog( "Enter second integer" );

int number1 = Integer.parseInt( firstNumber );

int number2 = Integer.parseInt( secondNumber );

int sum = number1 + number2;

JOptionPane.showMessageDialog( null, "The sum is " + sum,

"Sum of Two Integers", JOptionPane.PLAIN_MESSAGE );

}

}

Transient keyword is used by java programmers for variables, if the programmer does not want to store them permanently.

In case of serialization, the fields which are kept transient, are not the part of serialization process and not serialized.

Volatile is used along with the variable name, that can change its value without informing the JVM.

The system clock values are stored in Volatile variable.

They do not inform JVM when they change their value.

The term variables imply that those things may be changed or assigned with new value (at numerous places). This make the program harder to debug because it will be difficult to know when and where a global variable being changed and what was the consequence of that value changed.

You cannot invoke abstract methods directly. An abstract method looks like below:

public String getName() {}

It has no code inside it and can do nothing. You cannot invoke it directly. If you want to call this method then - we must extend the class that contains this method inside our class and then provide an implementation for this method and then invoke it:

Ex:

public String getName() {

return "Anand";

}

Once you place this code inside your class, then you can invoke it anytime you want by calling the method "getName()"

The solution to this problem is simple...

You should go to Options > Advance Options (Applications) > BB Key > Edit Permisions > Set to default.

The error will go away, BUT, you will lose your previous app permissionss and they won't have access to specific functions.

An Abstract class is similar to an interface. You cannot instantiate them, but you can extend them. Any class that extends the abstract class has to provide the implementation to the abstract methods. Hence these classes can be used as a skeleton to similar classes where some common functionality may be required. Such functionality can also be embedded into these classes. Unlike interfaces, abstract classes can have method code also. So they are very useful.
