Draw Triangle

Problem Statement:

Draw a triangle for a given size, using given character and pointing toward given direction.

Language:

Java

Platform:

Command Prompt

Command:

[Program] -size [Size] -char [Char] -direction [Direction]

Expected Input:

[Size]: Any positive integer. Error should be printed if non-positive integer or string is given.

[Char]: Any single char. Error should be printed if more then one char is given.

[Direction]: R/L/U/D for Right / Left / Up / Down. Error should be printed if any other input is given.

Note: The order of parameters may change.

Hint: First make programme with fix order of parameter to get a working code. Then attempt to process the command line input for parameter reordering. This approach is known as modular approach for programming.

Expected Output:

Print the triangle of given size in given direction using given character. See example for better understanding.

Example:

Interface:

$ java DrawTriangle -size 5 -char A -direction R

Output:

A

AA

AAA

AAAA

AAAAA

AAAA

AAA

Problem Statement:

Write a program to generate a table of given number from command prompt.

Language:

Java

Platform:

Command Prompt

Command:

[Program] [Input Number]

Expected Input:

[Input Number]: Any Integer (positive or negative)

Expected Output:

Table of given integer from 1 to 10.

Example:

Interface:
