Thread: Can't seem to understand how this output came

so I am a new to java and coding and doing some basic stuff please don't be hard on me if i am stupid

public class forloop {
	public static void main(String[] args) {
int N,M;
for (N=6; N>=0; N--) 
{ for (M=1; M<=N-1;M++)
System.out.print("*"); 
System.out.println(""); 
}
}
}

the output is

*****
****
***
**
*

It's supposed to be this way but when I practically tried to calculate the code I wasn't able to get it right
For the 1st run of loop N=6 and M=1 and Prints * (1st line)
2nd run of loop N=5 and M=2 and prints *(1st line)
3rd run of loop N=4 and M=3 and Prints * (1st line)
4th run of loop N=3 and M=4 and it Printsln " " (goes to 2nd line) [as the Value of M needs to be lesser than N to print a new "*" on the same line]
so the output seems to be

***
(and the switches to 2nd line and continues the calculation)

I am having a hard time explaining what I want to convey but if anyone gets it can you please guide me on where I am going wrong while calculating in real life?

One problem with the code is the formatting. Poor formatting makes the code hard to read and understand.
There should not be any code on a line following a { or before a }
The statements controlled by a for statement should be enclosed by {}s

   for(int x=1; x < 4; x++) {
     // some statement(s)
   }

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

The code has lost all its formatting. Logically nested statements should be indented. See the code sample I posted.
The statements should not all start in the first column.
The statements controlled by the for statement are not wrapped in {}s.
There should not be a statement on the same line following a {

Proper formatting makes code much easier to read and understand.

The way to see what the code is doing is to use paper and pencil to write down the values of the variables at the end of the line for each time a line is executed.
Write the values in columns with each column showing the values on one iteration of the loop.
for (M=1; M<=N-1;M++) // N = 6, M = 1 || N = 5, M = 1 etc
Continue for all the source lines.
