Logic used in the program to print Right Triangle pattern: Here we are using nested for loop, the outer loop is for rows, which runs from 0 till numberOfRows (this is 8 in our example), this means that it will print 8 rows of stars. Using For Loop. A right-angled triangle is a triangle with one of its interior angles equal to 90 degrees or any one angle is a right angle. SAMPLE OUTPUT: Enter Right Triangle Side A : 3. This means that the threshold in the close enough thing doesn't need to be that small for it to work. The inner loop is for column that will print one star in first row, two stars in second row and so on. Each iteration of outer loop will print one row of the pattern. This Java hollow right triangle star example uses if condition inside nested for loop to find the outside rows and display the hollow right triangle.
