Some Java codes

18 Aug
دي باقي الأكواد الي احنا شرحناها و مطبقناش عليها

دا اول واحد عشان نطبع المثلث بال * بطرقة ال for

CODE: تحديد الكل

public class array

{
public static void main(String args[])
{
for(int x =0 ; x<=4 ; x++)
{
for(int y = 4 ; y>=4-x ; y--)
{
System.out.print("*");
}
System.out.println();
}
}
}

Using For

CODE: تحديد الكل

public class Astric
{
public static void main(String args[])
{
for(int x =0 ; x<=4 ; x++)
{
for(int y = 0 ; y<=4-x ; y++)
{
System.out.print("*");
}
System.out.println();
}
}
}

Using While

CODE:

class While

{
public static void main(String args[])
{
int y=1;

while (y<=5)

{

int i =1;

while (i<=(6-y))

{

System.out.print("*");

i++;

} // End Of The While

System.out.println();

y++;

} // End of the First While
}
}

Using Do While

CODE: تحديد الكل

class while
{
public static void main(String args[])
{
int z=1;

do

{

System.out.println();

int i=1;

do {

System.out.print("*");

i++;

} while (i<=(6-z));

z++;

}while (z<=5);
System.out.println();
}
}

Using Switch To Print

CODE: تحديد الكل

import java
.util.Scanner;

class Switch {
public static void main
(String args[]) {

Scanner sc

= new Scanner(System.in);//create object from Scanner class
System.out.println("Enter Month Number :");
int month
= sc.nextInt();//read the number from the user (Like -----console.readeline();)

String season;
switch
(month) {
case 12
:
case 1
:
case 2
:
season
= "Winter";
break
;
case 3
:
case 4
:
case 5
:
season
= "Spring";
break
;
case 6
:
case 7
:
case 8
:
season
= "Summer";
break
;
case 9
:
case 10
:
case 11
:
season
= "Autumn";
break
;
default
:
season
= "Bogus Month";
}
System
.out.println("Month is in the " + season + ".");
}
}

Operator Using Scanner

CODE: تحديد الكل

import java
.util.Scanner;

public class Scanner
{
public static void main(String args[])
{
Scanner sc = new Scanner(System.in);
System.out.println("Enter First Number :");
int x
= sc.nextInt();
System.out.println("Enter Second Number :");
int y
=sc.nextInt();
int z = x*y;
System.out.println("The Result Is :" + z);

}
}

Revers Word

CODE: تحديد الكل

public class Revers
{
public static void main(String[] args){
String s = "Java";
int length = s.length();
System.out.println(length);
for (int i=length-1;i>=0;i--)
System.out.print(s.charAt(i));
System.out.println();
}
}
