Today due to my personal issues I can able to attend my class. Even thought with help of my friends I got to what was thought today.

Today class is about using datatypes how the programs are been excecuted. Datatypes are int, float, char, long, boolean , string etc. using this I excecute a program today.

firstly int defines number.

float defines decimals

char defines single letter(s)

long defines long number.

string defines words.

Using all this I did a program.

class write{

public static void main(String args[])

{

int a=2;

float b=0.9f;

string c=sobhika;

long d=20000000l;

char e=’d’;

System.out.println(a+” “+b+” “+c+” “+d+” “+e+” “)

}

}

finally after a one week one our class we today we entered into program . We did program in mint and that was very interesting. I personally did 5 mistakes and I corrected it.

Firstly, I put my program in text editor and I run it in terminal. My first mistake was a syntax error. And capital letter error. Once I corrected all my error I just figure it our.

I got with the doubt that what purpose we are using all this syntax . My trainer Arun sir explained it . And finally I got to why we use those.

And here is my cute program:

class helloworld{

public static void main(String args[])

{

System.out.print(“helloworld”)

}

}
