Thread: Easy.

I know this is easy to most of you. Even though I will be look stupid if
I will ask help about this simple problem. I'm not fun of using for loop
in my programs, I really don't know how to do it.

Output:

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

public class Ex1
{
  public static void main (String args[])
  {
 
	int x = 0;
	int y = 0;
 
	for(y=0;y<5;y++)
	{
		for(x=0;x<4;x++)
		{	  
		System.out.print("*");	
		}	
		System.out.println("*");
	}

Output:

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

public class Ex2
{
  public static void main (String args[])
  {
 
 
 
	for(int y=0;y<5;y++)
	{
		for(int x=0;x<y;x++)
		{	  
		System.out.print("*");	
		}	
		System.out.println("*");
	}		
 
	}
}

I made those simple codes on the upper. Now my problem is how can I make
an output like this, using for loop not just by simple System.out.print();

............*

........***
......****
....*****

PS: The Periods/dots aren't included in output, I just can't move the
asterisk in those positions.

Using your Ex2 as a base for it, notice how for(int x = 0; x < y; x++) will never be true the first time around, as both x and y would equal 0. This is the cause for you needing to add that extra star after the loop.
A better approach would be to set the outer loop to begin at 1 and test for EQUAL TO and LESS THAN.

As you've already got Ex2 done, i'll give you a rework of it so that you can understand and better solve this next step.

	public static void main(String args[]) {
 
		final int MAX_ROW = 5;
		final String ARROW = "->";
 
		for (int row = 1; row <= MAX_ROW; row++) {
 
			for (int col = 0; col < row; col++) {
				System.out.print("*");
			}
			System.out.println("");
		}
 
	}

Ofcourse the fix will be the same in both templates, I just hope you can try understand your problem better when values etc are clearer.

Using 2 for Loops and 2 SoP it's possible ?

You'll need 3 "SoP"s to complete it.
