System.out.print ("Enter a number")
line=1;
x=1;
while (line <=len)
{
while (a <=line)
{
System.out.print (x)
x++;
a=a+1;

Answer 2

You could use a single for loop.

Use a temp variable to keep track of whatever itteration you are on. Create another different variable and set it equal to. When teml reaches the different variable, reset the temp variable to the original value and move to the next line. Then increment the different variable. The different variable will then have a value of 2.
That process will keep repeating because of the loop. So temp will increase till 2, reset, and the different variable will keep increasing. So the different variable is really just how many numbers will be on a row, and the temp is how many we've already placed.

Inside the loop you can print the variable from the for loop. If the different variable is equal to the temp, you do not add a comma at the end of a number.

Answer 3

Just create an array, loop through it, and print each result through each loop through.
