In Pseudo-Code

int numberOfRows = 4; //You can change this number to adapt to the size of the triangle
int incrementalNumber = 0;
for (int i = 1; i = numberOfRows; i++) {
for (int j = 0; j < i; j++) { //iterates once the first row, twice the second row, and so on.
incrementalNumber++; //Increase this variable for every iteration
print((incrementalNumber % 2) + " "); //('% 2' = mod 2 = integer remainder after (multiple) division by 2 [0, 1]
//for example 9 % 4 = 1 since (integer division) 9/4 = (integer part) 2 with the remainder 1.
//Since the variable incrementalNumber will alter between odd and even, the remainder part will alter between 0 and 1, which is the number you print out on the screen.
} //print = (Java) System.out.print
println();
}

I think this is what you're asking for, although your image looks somewhat distorted. The code could however easily be modified to work with different distances between the numbers if needed.
If this is indeed schoolwork and you have difficulties then I recommend you brush up on your math, especially the algebra part.

Instead of using the number % 2 like that, if it was just going to be 1s and 0s, I would set a boolean variable to true to start with then in the loop set the boolean variable to not itself. then if else statement to print 1 or 0. Although your way would take fewer lines of code.

Naturally you could use a boolean if you want but since some programming languages don't interpret true = 1 and false = 0, and since I wouldn't want unnecessary if-statements, using modulo is not only a faster but also more beautiful solution.

plz can anybody write down a proper code for this program i desparately need it

Dream.In.Code has a policy by which we prefer to see a good faith effort on your part before providing source code for homework assignments. Please post the code you have written in an effort to resolve the problem, and our members would be happy to provide some guidance. Be sure to include a description of any errors you are encountering as well.

Thank you for helping us helping you.

The Pseudo-code I posted is practically java-code. If you can't translate it into real java code then I don't think you tried your best.
