First Lab of Software Technology II subject

For the whole first year, we learned C++. This year we learn Java for the subject 'Software Technology II'. Today we had the very first lab session for this subject. I could complete all the lab exercises within the lab session it-self. Special Thanks to the authors of the blog 'අපි Java ඉගෙන ගනිමු'. During my 2 months holiday after the 1st year 2nd semester exam, I went through that blog and learned the basic syntax of Java.

class Exercise1

{

public static void main(String args[])

{

System.out.println();

System.out.println("Hello World !");

System.out.println();

System.out.println("It's been nice knowing you.");

System.out.println();

System.out.println("Goodbye world !");

System.out.println();

}

}

class Exercise2

{

public static void main(String args[])

{

System.out.println("======================================");

System.out.println();

System.out.println("=         Student Information        =");

System.out.println(); 

System.out.println("======================================");

System.out.println();

System.out.println("= Name        :  ARDP Ranasinghe     =");

System.out.println();

System.out.println("= Reg No      :  DIS\\08\\M4\\1234      =");

System.out.println();

System.out.println("= Address     :  Malabe              =");

System.out.println();

System.out.println("======================================");

}

}

class Exercise3

{

public static void main(String args[])

{

System.out.println();

System.out.println();

System.out.println("* * * * *");

System.out.println();

System.out.println("* * * * *");

System.out.println();

System.out.println("* * * * *");

System.out.println();

System.out.println("* * * * *");

System.out.println();

System.out.println();

System.out.println("    *");

System.out.println();

System.out.println("   * *");

System.out.println();

System.out.println("  * * *" );

System.out.println();

System.out.println(" * * * *");

System.out.println();

System.out.println();

}

}

class Exercise4

{

public static void main(String args[])

{

System.out.println();

System.out.println();

System.out.println("* * * * *          *");

System.out.println();

System.out.println("* * * * *         * * ");

System.out.println();

System.out.println("* * * * *        * * *");

System.out.println();

System.out.println("* * * * *      * * * * *");

System.out.println();

System.out.println();

}

}

class Exercis3loops

{

public static void main(String args[])

{

System.out.println();

System.out.println();

for(int row=1; row<=4; row++)

{

for(int i=1; i<=5; i++)

{

System.out.print("* ");

}

System.out.println();

}

System.out.println();

for(int r=1; r<=5; r++)

{

for(int x=6; x>=r; x--)

{

System.out.print(" ");

}

for(int s=1; s<=r; s++)

System.out.print("* ");

System.out.println();

}

System.out.println();

}

}

P.S - Recently I closed the blog as I was continuously receiving bad comments from 'Anonymous' people. But after much thought I decided to continue writing my blog.
