One of my most recent assignments was to create a class called Triangle that would - given user input from the main method - take in the input to test if the hypothetical "triangle" is equilateral, isosceles, or scalene and then return that to main. ",triangle.triangleType ()); }//end test @Test public void test3 () { Abstract Class. Anyway, here's my code. Copyright 2022 Student Assignment Help. rev2022.12.9.43105. We recommend reading this tutorial, in the sequence listed in the left menu. In the above code, again we are using K variable to print spaces but this time we are decrementing it by 1,i.e, k= k-1 , after each loop of printing spaces get's over, so basically logic is same as per the 2nd code, but changing it a little bit it generates equivalent triangle. What's the difference? Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content.
