A Trick which help every new Java programmer and also "FOR" loop program for decrements of numbers, inside this post !!!!!

Hey guys, this time I want to tell you one short key so that you don't have to write down full line for example write down the "syso" and  press Ctrl + Spacebar, now tell me what you got. Of course "System.out.println();" and you can use same keys for other keywords. You don't need to writedown all words, just write starting words and press this keys then you got what you want. Isn't that cool ???? I hope this small trick help you a lot till you become professional Java programmer that is for lifetime.

Now in this post I just present small program of number decrements. And here it is.

________________________________________________


public class SimpleFor {

public static void main(String[]args){

for(int x=1; x<=21; x++){

for(int y = 1; y<=x;y++){

//System.out.print(" ");


System.out.print(x);
}

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

}

Now if you remove that "//" from "syso" from the above code, you know what I mean, then you got following output:

 1 

 2 2 

 3 3 3 

 4 4 4 4 

 5 5 5 5 5 

 6 6 6 6 6 6 

 7 7 7 7 7 7 7 

 8 8 8 8 8 8 8 8 

 9 9 9 9 9 9 9 9 9 

 10 10 10 10 10 10 10 10 10 10 

 11 11 11 11 11 11 11 11 11 11 11 

 12 12 12 12 12 12 12 12 12 12 12 12 

 13 13 13 13 13 13 13 13 13 13 13 13 13 

 14 14 14 14 14 14 14 14 14 14 14 14 14 14 

 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 

 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 

 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 

 18 18 18 18 18 18 18 18 18 18 18 18 18 18 18 18 18 18 

 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 

 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20

Now you can see the difference that is space matters a lot. Right guys???
