Java Programming

The methods in a class diagram represent the actions that the class can perform. For instance, a method with an add(x,y) method could add two integers while a getName() could return a variable containing the name of a person.

An unhandled exception is an Exception that is thrown by execution but is never caught by the program, which results in a nasty Exception Stack. This could be avoided by catching the exception in a try-catch statement, but it is not always appropriate to catch every possible exception. Sometimes the exception is the result of the client making a mistake rather than something that occurred where it is thrown, therefore the client should be informed of the exception. But most of the time it is user friendly to not propagate exceptions.

The parentheses are used in methods to specify arguments. Some methods don't use arguments; but it would in fact be more confusing, not less, to omit the parentheses in this case - because the parentheses give some kind of consistency.

The parentheses also help make it clear when something written after a dot is a field, and when it is a method. For this reason, in languages that allow you to either write or not write the parentheses for methods without arguments, I would always write them, for clarity and consistency.

JAVA is Group Of Technologies Like Java SE, Java EE, Java ME

and Java FX is a Latest Technology Released From SUN Micro Systems

Sun Developed Java FX as Counterpart to Microsoft's Graphics Libraries and Rich Support of Visual Studio to GUI Classes of .NET Framework.

But in JAVA FX We can Do some advanced Graphics Operations in Programming Apart From AWT & Swing of Java SE and Rich Internet Application Technologies Like Enterprise Java Beans (EJB),JSP Of Java EE.

The below method is written in the assumption that, the n numbers are sent as an ArrayList of Integer values.

public void computeSumAndAvg(ArrayList lst){ Iterator itr = lst.iterator();

int sum = 0;

float average = 0;

int count = 0;

while(itr.hasNext(){ Integer val = (Integer) itr.next();

sum = sum + val.intValue();

count++; }

average = sum/count;

System.out.println("Sum is: " + sum) ;

System.out.println("Average is: " + average) ; }

import java.util.Vector;

public class VectorTest {

/**

*/

public static void main(String[] args) {

//instantiating a vector

Vector vct = new Vector();

//Add objects to a vector

vct.add("One");

//getting values from the vector

String val = (String) vct.get(0);

//vector size

System.out.println("Vector size is: " + vct.size());

//removing elements from a vector

vct.remove(0);

}

In an if statement, the condition must be enclosed in parentheses.

i Would say it because when i used to use it it would run slow and i got a warning from java

Explicit means done by the programmer.

Implicit means done by the JVM or the tool , not the Programmer.

For Example:

Java will provide us default constructor implicitly.Even if the programmer didn't write code for constructor, he can call default constructor.

Explicit is opposite to this , ie. programmer has to write .

class Count

{

public static void main(String args[])

{

int i,c=0;

int n=args.length;

System.out.println("length is"+n);

for(i=0;i<args.length;i++)

{

System.out.println(args[i]);

c++;

}

System.out.println("number of words="+c);

}

Bear says bow string length is 86.125in & buss cable length 31in

One practical example would be an application that would need to compute interest earned on a savings account or multiple savings accounts at the end of the year. Another would be an application that tracks a person's name and age and then sorts them into similar or randomized groups.

the length of the array

#include<stdio.h>

#include<string.h>

int main()

{

char a[80];

int rotated_element_number[80];

int rotation;

int i;

int length;

printf("enter the word: \n");

gets(a);

length = strlen(a);

printf("the reversed string is:\n");

for( rotation=0; rotation<length; rotation++)

{

for( i=0; i<length; i++)

{

rotated_element_number[i] = i + rotation;

while(rotated_element_number[i] > (length-1)) rotated_element_number[i] -= length;

printf("%c", a[rotated_element_number[i]]);

}

printf("\t");

}

getchar();

return 0;

}
