Learn the basic concepts of Java such as loops, methods, and arrays.

Android Development with Java

This module will be our guide on getting started with Java. We'll start with a simple “Hello World” program and proceed to cover common concepts such as conditional statements, loops, math, and logic in Java. Then, we’ll move to more advanced concepts like inheritance, generics, and array lists, along with much more.
By the time we're done, we'll have enough knowledge to write simple Java programs.

# Problem statement
Implement a Java method that takes an *integer* size as input and **displays** a table that represents a [Pascal's triangle](https://en.wikipedia.org/wiki/Pascal%27s_triangle) using a *two-dimensional* array.  

## Function prototype
```java
void printPascalTri(int size)
```
## Sample input
```java
int size = 5;
```
## Sample output

*Print* Pascal's triangle of the size 5.<br>
Pascal's triangle is filled from the top towards the bottom. In *Pascal's triangle*: 

* **first** and the **second** *rows* are set to **1**. 
* Each *element* of the *triangle* (from the **third** row downward) is the **sum** of the element directly above it and the *element* to the **left** of the *element* directly **above** it. 


>**Note:** In order to move a value to the next line you can use `\n`.

## Pictorial representation
See the example *Pascal triangle*(**size=5**) below:
```java
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
```

In this challenge, you have to implement Pascal's triangle using a two-dimensional Array.
