Procedural programming
As a computer program marks coding so
that is calling for Procedural Programming. That means a record of programming
for telling into computer. And this is telling for step-by step. Procedural
programming languages take in JAVA, C, C++, FORTRAN, Pascal, and Basic etc...
Java
A high-level programming language
developed by Sun Microsystems... and having advantage of using this java that
is we can take example of you have Visual Basic and that is taking more space
but java is like MB so that is not taking that much of space. Oak was failed so
in 1995 Sun changed the name to Java and made to order the language.
Java is an object-oriented language
like to C++, but basic to remove language features that reason common
programming errors. Collected Java code can run on most computers because Java
interpreters and runtime environments Java is a common reason programming
language with a number of features Small Java applications are called Java
applets, nowadays this famous computer language.
And java has some principles such as
·
Statement
·
Function
·
Selection
·
Module
·
Subroutine
·
Parameter/Argument
·
Iteration/repetition
·
Variables
·
Procedure/
procedure cal
·
Sequence
·
Loop
·
Algorithms
Statement
Way plus
constructors are runs of statements, next to with variable meanings. The
statements give the sequence of events to be makes when a process or
constructor is call up. They can change the value of variables, make output,
process input, or respond to user input device action.
Here
having some statement such as
·
Looping
statements
·
While
statements
·
Do-While
statements
·
For
statements etc...
On example
for statement
If
(num> 18)
{
System.out.println
(“great Then" + num);
}
Function
Function
mean will go back an only one value after called. And this is use full to
insert functions and it is consist of input parameters. And it is Support for
closures and higher order functions and it is supporting for lazy assessment.
Selection
A Selection means a Selector for use
with a limit or Value anywhere careful link of Parameters and/or Values is
wanted.The principle is one as the character of the Parameter and/or Value to
use in creation a collection. The Selector line identifies the reason symbols.
If/else
selection
• Perform action only when state is right
• do different specific action when
state is false
• It’s like qualified operator
public
static void selectionSort1(int[] x) {
for (int
i=0; i<x.length-1; i++) {
for (int
j=i+1; j<x.length; j++) {
if (x[i]
> x[j]) {
//... Exchange elements
int temp =
x[i];
x[i] =
x[j];
x[j] =
temp;
}
}
}
}
Module
A module
or a modulemeaning can be defined as a logical unit of rest of
files. Income and its needs that can be side put together and organize in the
module store. This is use again by some other function.
And below
is the main divide of a module such as
Name of
the module
List of
introduction modules
List of
classes limited in this module
Public
class Model extends java.util.Observable {
privateint counter; //primitive, automatically initialised to
0
public Model(){
System.out.println("Model()");
Subroutine
It will take us a while mainly of the
part to get from first to last come again? This total means in fact. This is performance
part, of the "black box". This is including interface part. They are
the orders that the computer carry out when the method is called. Subroutines
can control any of the statement.And each declaration can name only one
parameter.
modifiers return-type
subroutine-name ( parameter-list
) {
statements
}
Parameter/Argument
Parameters are the variables that are
programmed as piece of a method declaration. Each parameter must have a single
name and a clear data style. Zero or additional String objects or an array of
them may be agreed as the parameter for that purpose.
Identifying method arguments
When you identify a method, you know
how to pass in order for it to make use of. These real advices are inside
addition following the method name. And before program is shown below, but this
time the arguments in the calls are highlighted.
Iteration/repetition
It is mean
repeating data process
An example for using this we can take
a word, phrase, or clause additionalThen once in a short means of access address
on a point. Iteration is a generalization of cursor. Useless or chance
repetition a tautology or pleonasm is a type of disorder that may divert or
turn off a person who reads.Iteration, similar to friction, is expected to make
heat in its place of development iteration is a single development cycle.
public static void cont (int n) {
while (a> 0) {
System.out.println (n);
a = a-1;
}
System.out.println
("Blastoff!");
}
Variables
A variable is a container that holds
values that are used in a Java program. Every variable have to be declared to
make use of a data type. For example, a variable might be stated to use one of
the eight primitive data types: int, long, float, double, char or Boolean.
String and, every variable must be given a first value before it can be used.
Here has some data type such as
·
Int:
that is Integer that mean it if for number
·
Long:
that is mean of large number
·
Float:
this is using for decimal number like 1.5
·
Double:
this is use for large decimal number like 1322222548788.5
·
Character: this is use for one letter example
BCAS
·
Boolean:
it is mean True or False (1,0)
·
String:
this use for text
Example
Int Arm=1;
Int
arm2=2;
Int
tot=arm+arm2;
}
Procedure/
procedure call
An ordered set of tasks for performing
some action that mean it is checking for one buy one. That one would go after
in order to complete a task. That is step-by-step order of activities or track
of action that must be go behind in the same order to correctly do a task.
Repetitive procedures are called routines
Public
class arm
{
Public
static void main (String args[])
{
Int a = 5;
Int b= 6;
Int c=
a+b;
System.out.println(“answer
is”+c);
}
}
This is
small example for this procedure.
Sequence
Serial agreement in which things
follow in logical arrange or a regular model. Arrange in a sequenceDetermine
the order of constituents inAll programmers are known with writing in order
programs.You've most likely in print a program that displays "Welcome to
java” or sorts a file of names, or computes a list of main numbers. These are
sequential programs. Each has an opening, an end, a sequence, and at any set
time through the runtime of the program there is an only one end of finishing.A
strand is a on its own in order run of control inside a program.
Example…
DefMonth =
["Jan","Feb","Mar","Apr",”May”,”June”,”July”,”Aug”,”Sep”,”Oct”,”Nov”,”Dec”];
Loop
A loop is a method of do again outline
of code more Then once. The block of code limited within the loop will be
meeting all over again and again until the condition needed by the loop is
meeting.
For example, you could set up a loop
to print out the even numbers between 0 and 10. The code that gets complete all
time the loop is run will be the printing out of an even number, the order the
loop is looking to meet is getting 10. Int[] num(1, 2, 3, 4, 5, 6, 7, 8, 9);
Here having some type such as
·
Indeterminate
·
Determinate
Indeterminate
That
meanan unfixed loop does not know how many times it will run.
Determinate
A
determinate loop identifies closely how many times it will loop.
Algorithms
Algorithms the polymorphic algorithms
explain here are pieces of reusable functionality make available by the Java
platform. All of them come from the
group of
class, and all get the type of static way whose first fight is the group on
which the process is to be complete.
publicint[]
selectionSort(int[] data){
intlenD =
data.length;
int j = 0;
inttmp =
0;
for(int
i=0;i<lenD;i++){
j = i;
for(int k
= i;k<lenD;k++){
if(data[j]>data[k]){
j = k;
}
}
tmp =
data[i];
data[i] =
data[j];
data[j] =
tmp;
}
return
data;
}
